Snapshot

The essentials in ~60 seconds — every line is drawn from the cited sources below.

What it is
Mesonephric-like adenocarcinoma (MLA) is a rare gynecologic cancer recognized recently that can arise in the endometrium, ovaries, adnexa and other extrauterine sites and is often associated with endometriosis; classic mesonephric carcinoma is thought to derive from Wolffian/mesonephric remnants and most commonly occurs in the lateral uterine cervix but can arise elsewhere in the uterine corpus. [1][2][3][4][5][6]
Survival
Reported median overall survival in one institutional series was 15 months (95% CI: 2.2-27.8 months), and the literature suggests an overall poor prognosis with the majority presenting at advanced stages. [7]
Standard treatment
Initial management in reported series has been upfront surgical resection with most patients recommended to receive adjuvant therapy; when tumors involve the uterine myometrium, treatment has been similar to that for endometrial cancer. [7][5]
Key test
HER2 testing by immunohistochemistry can change therapy selection because NCCN recommends Trastuzumab Deruxtecan (T-Dxd) for recurrent HER2 (2-3+) endometrial carcinoma, and HER2 expression has been reported in MA/MLA. [8]
Biggest challenge
The main clinical problems are advanced-stage presentation and overall poor prognosis, together with diagnostic confusion (frequent misclassification, e.g. as clear cell carcinoma) due to overlapping morphology and marker expression. [7][9][1]

Key numbers & factors

Risk factors

  • ▲ increases riskEndometriosis — MLA is often associated with endometriosis. [1][2]
  • ▲ increases riskAtypical mesonephric hyperplasia — Described as a potential premalignant lesion. [10]

Biomarkers

  • PAX8 · Diagnostic: MLAs typically show diffuse strong PAX8 positivity. [11][12]
  • Estrogen receptor (ER) · Diagnostic: MLAs are typically ER negative. [11][12]
  • GATA3 · Diagnostic: high sensitivity and specificity for identifying mesonephric and mesonephric-like carcinomas. [13]
  • TTF1 · Diagnostic: often positive in mesonephric-like carcinomas and may help when GATA3 is negative. [14][13]
  • CD10 · Diagnostic: often positive in MLAs. [11][13]
  • c‑KIT (CD117) protein expression · Observed in the majority of mesonephric carcinomas (10/12; 83%) but no KIT mutations detected in that series; correlation with KIT-activating mutations is unresolved. [3]
  • KRAS mutations · Molecular: KRAS somatic mutations reported in some uterine and urinary-tract mesonephric(-like) cases. [15][16][10]
  • ARID1A / ARID1B / SMARCA4 · Molecular: mutations in chromatin remodeling genes present in 62% of mesonephric carcinomas. [2]
  • 1q gain (copy number alteration) · Genomic: most common copy number alteration, found in 12 (75%) mesonephric carcinomas. [2]
  • Tumor mutational burden (TMB) / MSI · MLCS cases had low tumor mutational burden and were microsatellite stable. [17]
  • HER2ActionableTherapeutic biomarker: HER2 expression was present in 14/21 MA/MLA tumors and HER2 (2-3+) status can guide use of Trastuzumab Deruxtecan per NCCN in recurrent endometrial carcinoma. [8]
  • FOLR1ActionableTherapeutic biomarker: met current MIRV treatment criteria in one case and showed variable expression in others, supporting exploration of MIRV-based approaches. [8]
  • Napsin‑A · Diagnostic: positive in a subset (17/48, 35.4%) of MA/MLA and can contribute to misclassification as clear cell carcinoma. [18][9]
  • p53 · Immunohistochemistry: reported wild-type staining in all tumors in one series. [14]
  • Mismatch repair proteins (MMR) · All endocervical adenocarcinomas examined were proficient in all four MMR proteins. [19]
  • PIK3CA / PTEN · Genomic: one series reported occasional PIK3CA mutations (1/13) while another reported all mesonephric carcinomas lacked PIK3CA and PTEN mutations (reports vary across series). [3][2]

9 sections — tap any heading to expand its cited detail. Key points are above.

Overview8 points
  • Mesonephric carcinoma is a rare gynecologic malignancy thought to derive from Wolffian/mesonephric remnants. [3][5][2]3 sources
  • MLA arises in the endometrium, ovaries, and other extrauterine sites and is often associated with endometriosis; an analogous tumor occurs in the adnexa (female adnexal tumor of probable Wolffian origin). [1][2]
  • This tumor usually occurs in the lateral wall of the uterine cervix. [4][2]
  • Mesonephric carcinoma can, in exceptional cases, arise in the uterine fundus or elsewhere in the uterine corpus. [4][5]
  • Mesonephric-like adenocarcinoma (MLA) is a rare gynecologic malignancy that has only been recognized in the last decade. [1]
  • Mesonephric-like neoplasms exhibit a relatively constant morphological appearance with an admixture of architectural patterns dominated by small glands or tubules, some containing luminal eosinophilic colloid-like material. [14]
  • The authors recommend these tumours be termed "mesonephric-like adenocarcinomas" until their histogenesis is firmly established. [14]
  • Immunohistochemistry is necessary in relatively few cases; knowledge of the potential immunoreactivity of the antibodies used is required for immunohistochemical studies. [20]
Epidemiology3 points
  • Mesonephric adenocarcinoma (MLA) is a rare gynecologic malignancy primarily arising in the uterine corpus and ovaries. [6]
  • The current study presents two cases of uterine corpus mesonephric carcinoma with sarcomatous components that occurred in postmenopausal women. [5]
  • Mesonephric adenocarcinomas and mesonephric-like adenocarcinomas can arise in the urinary tract, including the urinary bladder, the perirenal region, and the ureter. [16]
Key biomarkers20 points
  • Immunohistochemically, mesonephric proliferations/tumours are diffusely and strongly positive for PAX8, are negative for ER (and PR is typically negative), and show patchy cytoplasmic staining for p16; recent data also report diffuse PAX2 expression in mesonephric remnants and hyperplasias. [12][14][21]3 sources
  • Sources describe MLAs as typically showing diffuse strong PAX8 positivity and ER negativity; they are often positive for TTF-1, CD10, and GATA3, and show negative or only focal weak/moderate SOX17 staining. [11][22]
  • Across series, TTF1 nuclear staining was frequent in mesonephric-like carcinomas and infrequent in mesonephric carcinomas: in one series all except one tumour showed often-diffuse TTF1 nuclear staining; in another, TTF1 was positive in 5/5 mesonephric-like carcinomas and 1/8 mesonephric carcinomas. [14][13]
  • KRAS somatic mutation was reported in both uterine mesonephric adenocarcinoma cases studied; a KRAS G12C somatic mutation was detected in one urinary-tract mesonephric-like adenocarcinoma case, while hotspot mutations in KRAS, NRAS, and PIK3CA were not present in other tested cases. [15][16]
  • HPV DNA was not detected in the unusual endocervical adenocarcinoma subtypes studied (except a single serous case), and authors noted that mesonephric adenocarcinoma may be identified by negative CEA, ER, and PR stains; CEA was consistently negative in clear cell carcinomas and in a single mesonephric adenocarcinoma in the reported series. [21][14]
  • Mutations in chromatin remodeling genes (ARID1A, ARID1B, or SMARCA4) were present in 62% of mesonephric carcinomas. [2]
  • All mesonephric carcinomas lacked mutations in PIK3CA and PTEN. [2]
  • The most common copy number alteration was 1q gain, found in 12 (75%) mesonephric carcinomas. [2]
  • Mesonephric carcinoma is characterized by molecular alterations that differ from those of more common variants of cervical and endometrial adenocarcinoma, which harbor KRAS/NRAS mutations in 7% and 25% of cases, respectively. [2]
  • c-KIT immunohistochemical expression was observed in the majority of mesonephric carcinomas (10/12; 83%), but no KIT mutations were detected in that series. [3]
  • Mesonephric carcinoma and clear cell carcinoma can both be negative for estrogen receptor and p16, contributing to diagnostic difficulty; Napsin-A and AMACR expression is significantly higher in clear cell carcinomas than in mesonephric carcinomas and is helpful in distinguishing them. [9]
  • Additional mutations reported in one series included CTNNB1 (2/13, 15%), TP53 (2/13, 15%), and PIK3CA (1/13, 8%). [3]
  • HER2 expression was present in 14/21 MA/MLA tumours; HER2 (2+) was seen in two cases by both criteria, with no HER2 (3+) identified. [8]
  • FOLR1 met current MIRV treatment criteria in one case, while ten others showed expression ranging from 5% to 70%. [8]
  • Napsin-A staining was positive in 17 of 48 cases (35.4%) of MA/MLA, with focal granular cytoplasmic expression ranging from 1% to 40%. [18]
  • MLCS cases had low tumor mutational burden and were microsatellite stable. [17]
  • GATA3 had the highest sensitivity and specificity (91% and 94%) compared with TTF1 (45% and 99%), CD10 (73% and 83%), and calretinin (36% and 89%) for identifying mesonephric and mesonephric-like carcinomas. [13]
  • An inverse staining pattern between GATA3 and TTF1 was observed, and it was suggested that TTF1 may be useful when GATA3 is negative in small biopsies where mesonephric or mesonephric-like carcinoma is suspected. [13]
  • All tumours in a reported series exhibited wild-type staining with p53. [14]
  • All endocervical adenocarcinomas including variants and lower uterine segment tumours were proficient in all four mismatch repair proteins in the examined series. [19]
Biology & pathways2 points
  • MLA shows morphologic, immunohistochemical, and molecular homology with cervical mesonephric adenocarcinoma. [1]
  • Atypical mesonephric hyperplasia (MNH) has been reported to harbor pathogenic KRAS mutations and gain of chromosome 1q, suggesting these alterations play an important role in early mesonephric carcinogenesis. [10]
Standard management7 points
  • No targeted molecular therapeutic options have been identified for mesonephric carcinoma to date; targeted therapy with Imatinib has been attempted in tumors thought related to Wolffian-origin lesions, with mixed success. [3]
  • When tumors are located in the uterine myometrium, treatment has been similar to that for endometrial cancer. [5]
  • The National Comprehensive Cancer Network (NCCN) recommends Trastuzumab Deruxtecan (T-Dxd) as second-line therapy for recurrent HER2 (2-3+) endometrial carcinoma. [8]
  • Although most tumors did not meet current biomarker thresholds for Trastuzumab or MIRV monotherapy, detectable expression supports exploring anti-HER2 T-Dxd and MIRV combination treatments in selected MA/MLA cases. [8]
  • Cytology proved to be extremely helpful in supporting the clinical impression of an apparent advanced ovarian cancer; when the cytologic diagnosis does not match the clinical impression, communication between the cytologist or pathologist and the clinician is essential. [23]
Show 2 lab & early-research findings
  • In a reported case of uterine fundus mesonephric adenocarcinoma, the patient underwent hysterectomy with bilateral salpingo-oophorectomy and pelvic lymph node dissection, had no lymph node or distant metastasis, and remained free of relapse after 20 months of surveillance without adjuvant therapy. [4]
  • In a case series, all patients underwent upfront surgical resection and were recommended adjuvant therapy after surgery. [7]
Treatments & compounds studied8 treatments

Chemotherapy

  • platinum-based neoadjuvant chemotherapy: Neoadjuvant (before surgery)Pretreatment cytology slides were available from patients treated with platinum-based neoadjuvant chemotherapy who were believed to have ovarian cancer based on clinical findings. [23]

Targeted therapy

  • RAS/MAPK pathway inhibitors: Inhibitors of the RAS/MAPK pathway have been proposed as a potential therapeutic approach for mesonephric carcinoma. [2]
  • Trastuzumab Deruxtecan (T-Dxd): biomarker-selectedThe DESTINY-PanTumor02 study reported strong responses to Trastuzumab Deruxtecan (T-Dxd), an antibody-drug conjugate targeting HER2, in multiple HER2+ chemoresistant tumors including gynecologic carcinomas. [8]
  • Mirvetuximab soravtansine (MIRV): Recurrent or later-line · platinum-resistant · biomarker-selectedMirvetuximab soravtansine (MIRV), which targets folate receptor-1 (FOLR1), is FDA-approved for platinum-resistant tubo-ovarian cancers with ≥75% moderate/strong staining, and studies report meaningful responses to MIRV combination therapy even at lower FOLR1 expression.

    • “After 20 months of surveillance without adjuvant therapy, she remains free of relapse.”

Other

  • adjuvant therapy: Adjuvant (after surgery)Patients in the same series were recommended adjuvant therapy after surgery. [7]
Staging & risk3 points
  • In one institutional series there were 6 uterine, 5 ovarian, and 2 cervical MNAC/MLA cases. [7]
  • In that series, at presentation 7 patients were diagnosed at stage I, 2 at stage II, 3 at stage III, and 1 at stage IV. [7]
  • In a separate series, MLCS patients were diagnosed at FIGO stage I (n=3), stage II (n=2), stage III (n=2), and stage IV (n=1). [17]
Prognosis6 points
  • Median overall survival in one institutional series was 15 months (95% CI: 2.2-27.8 months). [7]
  • Current literature suggests an overall poor prognosis for MNACs/MLAs with the majority presenting at advanced stages. [7]
  • In that series, 9 of 13 patients had completed treatment and had no evidence of disease. [7]
  • Mesonephric carcinoma is commonly mistaken for clear cell carcinoma because of overlapping morphologic features. [9]
  • Atypical mesonephric hyperplasia is described as a potential premalignant lesion. [10]
  • Although the follow-up period was short in the current cases, no metastatic disease was identified in the second case. [5]
What we don't know yet7 points
  • There is controversy about the morphologic, immunohistochemical, and molecular criteria that should be used to establish a diagnosis of mesonephric adenocarcinoma (MLA). [1]
  • It remains unresolved whether MLA originates from mesonephric (Wolffian) remnants or from Müllerian duct-derived tissue. [6]
  • It is unclear whether c-KIT immunohistochemical expression in mesonephric carcinoma correlates with KIT-activating mutations. [3]
  • The molecular relationship between female adnexal tumor of probable Wolffian origin (FATWO) and mesonephric carcinoma is uncertain because FATWO lacks KRAS/NRAS mutations that are characteristic of mesonephric carcinoma. [24]
  • The pathogenesis and the key molecular events in mesonephric carcinoma are not known. [2]
  • HER2 and FOLR1 biomarkers have not been adequately evaluated in mesonephric and mesonephric-like adenocarcinomas. [8]
  • Napsin-A expression is present in a subset of mesonephric-like and mesonephric adenocarcinomas and may contribute to misclassification as clear cell carcinoma; pathologists should use a panel of markers rather than relying on a single marker. [18]

Mesonephric-like Adenocarcinoma of the Female Genital Tract: A Comprehensive Review of Clinicopathological, Immunophenotypic, Molecular Features, and Clinical Management

International journal of surgical pathology · Jun 2026 · comprehensive review

mesonephric-like adenocarcinoma (MLA)mesonephric adenocarcinoma (MA)female genital tractuterine cervix

This is a comprehensive review summarizing clinicopathologic, immunophenotypic, and molecular features of mesonephric-like adenocarcinoma (MLA) of the female genital tract. The authors report that MLA shows diverse histologic patterns, is typically negative or only focally positive for ER, is positive for TTF-1, CD10, and GATA3 immunostains, and often harbors KRAS mutations. They note that MLA resembles mesonephric adenocarcinoma histologically and molecularly but, unlike MA, is not associated with mesonephric remnants. The review aims to improve clinicians' and pathologists' recognition of this rare tumor type.

Key findings
  • MLA is a recently recognized rare malignancy of the female genital tract with histomorphology, immunohistochemistry, and molecular characteristics similar to mesonephric adenocarcinoma but not associated with mesonephric remnants.
  • Histologic patterns described for MLA include tubule-like, glandular, papillary, solid, sex cord-like, trabecular, retiform, cribriform, glomeruloid, and spindle cell patterns.
  • Immunohistochemically, most MLAs show negative or focal weak expression for ER and are positive for TTF-1, CD10, and GATA3.
  • Molecularly, these tumors often harbor KRAS gene mutations.
Limitations: This is a narrative review rather than primary original data.; No systematic review or meta-analytic methods are described in the abstract.; MLA is a rare tumor, so primary evidence summarized may be limited in quantity and quality.; The abstract does not report treatment or clinical outcome data..

Provides a clinicopathologic, immunophenotypic, and molecular summary intended to help pathologists and clinicians recognize and diagnose mesonephric-like adenocarcinoma.

HER2 and FOLR1 Expression in Mesonephric and Mesonephric-Like Adenocarcinomas in the Gynecologic Tract

International journal of gynecological pathology : official journal of the International Society of Gynecological Pathologists · May 2026

Trastuzumab-deruxtecan-t-dxdmesonephric adenocarcinoma (cervix)mesonephric-like adenocarcinoma (endometrium)mesonephric-like adenocarcinoma (ovary)

The authors measured HER2 and FOLR1 protein expression by immunohistochemistry in 21 mesonephric and mesonephric-like gynecologic adenocarcinomas (13 endometrial, 5 ovarian, 3 cervical). HER2 was detectable in 14 of 21 tumors (two cases scored 2+ and many scored 1+, with no 3+ cases), while FOLR1 met MIRV eligibility in one case and ten additional tumors had 5–70% expression. Most tumors did not meet current thresholds for HER2- or FOLR1-targeted monotherapy, but the authors suggest detectable expression could justify exploring T-Dxd and MIRV combinations in selected cases.

Reported effects: Total cases assessed 21 · endometrial cases 13, n=21 · +9 more

Studied with: trastuzumab deruxtecan + mirvetuximab soravtansine.

Key findings
  • HER2 expression was present in 14/21 tumors.
  • HER2 (2+) was seen in two cases by both EC and GaC criteria; no HER2 (3+) was identified.
  • Twelve other cases showed HER2 (1+) by endometrial cancer (EC) criteria; only four met 1+ by GaC criteria.
  • FOLR1 met current MIRV treatment criteria in one case; ten other cases showed FOLR1 expression ranging from 5% to 70%.
  • Most tumors did not meet current biomarker thresholds for trastuzumab (HER2) or MIRV monotherapy.
Limitations: Small sample size (21 cases).; Observational immunohistochemical study of archival tumors only — no treatment or clinical outcome data provided.; Heterogeneous primary sites (cervix, endometrium, ovary) which may affect biomarker distribution.; Use of different scoring criteria (EC vs GaC) produced discordant HER2 categorization, which may limit generalizability..

The authors performed Napsin-A immunohistochemistry on whole-slide sections from 48 mesonephric and mesonephric-like adenocarcinomas and carcinosarcomas. Napsin-A was positive in 17/48 cases (35.4%), with focal granular cytoplasmic staining in 1–40% of cells; positivity occurred in 13/32 MLAs, 2/13 MAs, and 2/3 carcinosarcomas. The study concludes that Napsin-A is expressed in a substantial subset of these tumors and that reliance on a single marker could lead to misclassification as clear cell carcinoma.

Reported effects: Napsin-A positive overall 35.4%, n=48 · Range of focal granular cytoplasmic expression · +3 more

Key findings
  • Napsin-A staining was positive in 17 of 48 cases (35.4%), with focal granular cytoplasmic expression ranging from 1% to 40%.
  • 13/32 (40.6%) mesonephric-like adenocarcinomas (MLAs) were Napsin-A positive.
  • 2/13 (15.4%) mesonephric adenocarcinomas (MAs) were Napsin-A positive.
  • 2/3 (66.7%) mesonephric or mesonephric-like carcinosarcomas were Napsin-A positive.
  • Because of morphologic and immunohistochemical overlap, Napsin-A expression in MA/MLA may contribute to misclassification as clear cell carcinoma.
Limitations: Observational pathology series without reported clinical outcome correlation; Relatively small overall sample size and very small subgroup sizes (e.g., n=3 carcinosarcomas); Findings are based solely on immunohistochemistry on tissue sections; no clinical or molecular correlation reported in the abstract.

The Clinical Characteristics and Treatment Outcomes of Mesonephric Tumours of the Uterine Cervix: A Systematic Review and Proposal of Embryologically-Oriented Surgical Resection

Journal of clinical medicine · Dec 2024 · systematic review of case reports and case series

mesonephric adenocarcinoma of the uterine cervixcervical mesonephric adenocarcinoma (MNAC)

This systematic review pooled 49 publications describing 91 cases of cervical mesonephric adenocarcinoma. Most reported cases were stage I and hysterectomy was the most common surgical procedure; median follow-up was 29 months. Disease recurrence occurred in about one-third of cases (35.2%) with a median disease-free survival of 24 months; at follow-up 64.8% were in remission and 27.4% died of disease progression. The authors propose an embryologically oriented surgical approach based on their appraisal of existing surgical and adjuvant therapies.

Reported effects: included_publications 49, n=49 · cases_included 91, n=91 · +7 more

Key findings
  • 49 publications were included in the analysis, describing 91 MNAC cases.
  • Most patients had stage I disease (70.8%) (n = 51).
  • Hysterectomy was performed in 77 patients.
  • The median follow-up was 29 months (range 1-199 months).
  • Disease recurrence was observed in 35.2% (n = 25) of the cases.
  • Median disease-free survival (DFS) was 24 months (range 1-199).
  • At follow-up, 64.8% (n = 46) of patients remained in remission irrespective of the treatment modality.
  • 27.4% (n = 20) died due to disease progression.
Limitations: Evidence derives from case reports and case series rather than controlled trials.; Relatively small total number of cases (91) for pooled inference.; Heterogeneous and retrospectively reported treatments and outcomes across included publications.; Potential publication and selection bias inherent to systematic reviews of case reports/series.; Follow-up duration was variable (range 1–199 months) which may affect comparability of outcomes.; No randomized or controlled data available to support the proposed surgical approach..

Diagnosis, Treatment and Prognosis of Mesonephric Adenocarcinoma of the Vagina: A Literature Review and a Case Report

Journal of clinical medicine · Jul 2023 · systematic literature review of case reports/series plus a single case report

mesonephric adenocarcinoma of the vagina

The authors performed a systematic review of the literature and report one additional laparoscopic case, assembling 13 published cases of vaginal mesonephric adenocarcinoma. They summarize patient features (median age 52), diagnostic methods, that most patients underwent upfront surgery and many received adjuvant therapy, and report a mean follow-up of 6 years. The authors state that a minimally invasive approach may be feasible after multidisciplinary evaluation. Because the review is limited to a small number of case reports and series, conclusions about optimal management remain uncertain.

Reported effects: number_of_cases 13 · median_age 52, n=13 · +5 more

Key findings
  • Thirteen cases of mesonephric adenocarcinoma (MA) of the vagina were identified in the literature, including the authors' case report.
  • Median age at diagnosis was 52 years.
  • The majority of patients reported vaginal bleeding as a symptom (38%).
  • Ultrasound, followed by MRI and CT, were the most used diagnostic tools.
  • In 54% of cases a surgical biopsy was performed.
  • 92% of patients underwent upfront surgery (open access or vaginal resection); one case was managed fully by minimally invasive surgery.
  • 68% of patients received adjuvant treatment with chemotherapy, radiotherapy, or both.
  • Mean follow-up period reported was 6 years.
  • Authors conclude a minimally invasive approach seems feasible after multidisciplinary evaluation, but call for reporting future cases and follow-up data.
Limitations: Very small total sample (13 cases) drawn from case reports and case series.; Included evidence consists of uncontrolled observational reports and a single case report, preventing comparative conclusions.; Likely heterogeneity in diagnostic and treatment approaches across reported cases.; Potential publication and reporting bias inherent to case-report literature.; Abstract does not report systematic review methods details (search dates, eligibility criteria, risk-of-bias assessment) limiting appraisal..

Mesonephric Adenocarcinoma and Mesonephric-like Adenocarcinoma of the Urinary Tract

Modern pathology : an official journal of the United States and Canadian Academy of Pathology, Inc · Jan 2023 · case series

mesonephric adenocarcinomamesonephric-like adenocarcinomaurinary tracturinary bladderperirenal regionureteruterine cervixovaryendometrium

This study reports a case series of six mesonephric (MA) or mesonephric-like (MLA) adenocarcinomas arising in the urinary tract and describes their morphology, immunophenotype, and limited molecular findings. All six tumors were Pax8-positive and showed a luminal pattern of CD10 staining (CD10 unavailable in one case); a KRAS G12C mutation was found in one case, and other tested hotspot mutations were absent. The authors propose classifying urinary-tract tumors with mesonephric remnants as MA and those associated with Müllerian-type precursors as MLA.

Reported effects: MA in urinary bladder cases 4, n=6 · MA in perirenal region cases 1, n=6 · +4 more

Key findings
  • Characterized 4 cases of MA in the urinary bladder (1 woman and 3 men), 1 case of MA in the perirenal region (woman), and 1 case of MLA in the ureter (woman).
  • All cases (6/6) were diffusely positive for Pax8.
  • All displayed a luminal pattern of CD10 staining, except case 4 for which CD10 immunostain was not available for review.
  • GATA3 expression was variable: focally positive in cases 1, 2, and 6; negative in case 3; diffusely positive in case 5.
  • TTF-1 was diffusely expressed in cases 1 and 3 and negative in cases 2, 5, and 6.
  • A KRAS G12C somatic mutation was detected in case 6; hotspot mutations in KRAS, NRAS, and PIK3CA were not present in other tested cases.
  • Authors conclude urinary-tract MAs and MLAs share morphology and immunophenotype with their counterparts in the female genital tract and propose a classification based on origin (mesonephric remnants/Wolffian vs Müllerian-type precursors).
Limitations: Very small number of cases (n=6).; Retrospective case series without systematic clinical outcome or follow-up data reported.; Molecular testing appears limited (hotspot testing reported) and not uniformly applied to all cases.; One case lacked CD10 immunostain availability, limiting uniform immunophenotypic assessment..

The complex and often confusing history, histology and histogenesis of mesonephric, STK11 adnexal tumour and mesonephric-like neoplasms of the upper female genital tract (including broad ligament)

Histopathology · Sep 2022

mesonephric hyperplasiamesonephric carcinomarete cyst/cystadenomafemale adnexal tumour of Wolffian origin (FATWO)STK11 adnexal tumourmesonephric-like adenocarcinomaendometrioid carcinomaupper female genital tractbroad ligament

This narrative review summarizes the history, histology and histogenesis of mesonephric and mesonephric-like lesions of the upper female genital tract (including the broad ligament). It describes common upper-tract lesions (rete cyst/cystadenoma and FATWO), introduces the recently recognized STK11 adnexal tumour (often associated with Peutz-Jeghers syndrome, ~50%), and discusses mesonephric-like adenocarcinoma, which resembles mesonephric carcinoma but is currently favoured to be of Müllerian derivation and can mimic other entities such as endometrioid carcinoma.

Key findings
  • Mesonephric lesions in the female genital tract are uncommon, and upper tract lesions are much less frequent than lower tract mesonephric proliferations.
  • The most common upper tract lesions include rete cyst/cystadenoma and female adnexal tumour of Wolffian origin (FATWO).
  • Integration of morphological, immunohistochemical and molecular studies on FATWOs has enabled recognition of a novel entity, the STK11 adnexal tumour.
  • The STK11 adnexal tumour is often associated with Peutz-Jeghers syndrome (~50%) and frequently has a salivary gland morphology but an unknown origin.
  • 'Mesonephric-like' adenocarcinoma has striking similarities to mesonephric carcinoma but is currently favoured to be of Müllerian derivation based on its association with other Müllerian tumours and molecular findings.
  • Mesonephric-like adenocarcinoma may histologically mimic both FATWOs and STK11 adnexal tumours; the most common mimicker is endometrioid carcinoma.
Limitations: Narrative review without new primary data or quantitative synthesis.; Upper-tract mesonephric lesions are rare, so source data are likely limited to small case series and reports.; Origins of some entities remain uncertain (e.g., STK11 adnexal tumour described as of unknown origin; mesonephric-like adenocarcinoma is 'favoured' to be Müllerian but not definitively proven)..

A rare case of primary ovarian mesonephric adenocarcinoma and a review of the literature

Annali italiani di chirurgia · Mar 2022 · case report

ovarian mesonephric adenocarcinomaovarian carcinomamesonephric carcinoma

This paper reports a single case of mesonephric carcinoma occurring in the ovary of a 58-year-old woman and includes a brief review of the literature. The frozen section of the left adnexal mass was reported as malignant. The authors emphasize that ovarian mesonephric carcinoma is very rare, shows diverse morphological patterns, and that combined immunohistochemical and morphological evaluation is important for diagnosis. They note that correct diagnosis could alter treatment approaches and enable development of targeted therapies.

Key findings
  • Reported a single case of primary mesonephric carcinoma located in the ovary (left adnexal mass) in a 58-year-old patient.
  • Frozen section histology of the left adnexal mass indicated a malignant lesion.
  • Ovarian mesonephric carcinoma is very rare and exhibits varied morphological patterns.
  • Authors recommend evaluating immunohistochemical and morphological findings together when pathology does not fit common ovarian carcinomas.
  • Authors state that correct diagnosis of these tumors, which have different molecular developmental pathways, could change treatment schemes and promote development of targeted therapies.
Limitations: Single-patient case report — findings are not generalizable.; No detailed clinical course, treatment, or outcome/follow-up data are reported in the abstract.; No molecular characterization or systematic comparison with other ovarian carcinomas is provided in the abstract.; No controlled data or statistical analysis — descriptive only..

Mesonephric Adenocarcinoma of the Vagina Harboring TP53 Mutation

Diagnostics (Basel, Switzerland) · Jan 2022 · case report

vaginal mesonephric adenocarcinomamesonephric adenocarcinoma

This is a case report of a 52-year-old woman with a 2.5-cm vaginal mesonephric adenocarcinoma. Pathology and immunostaining confirmed mesonephric differentiation, and targeted sequencing identified activating KRAS p.G12D and truncating TP53 p.E286* mutations with absent p53 immunoreactivity. The authors note that TP53 mutations are very uncommon in mesonephric lesions based on their literature review.

Key findings
  • Presented a 52-year-old woman with a 2.5-cm mass of the left upper vagina; biopsy showed poorly differentiated adenocarcinoma and she underwent radical surgical resection.
  • Histology showed diverse architectural patterns typical of mesonephric adenocarcinoma with hyaline-like intraluminal secretions and prominent desmoplastic stroma.
  • Immunostaining was positive for mesonephric markers GATA3, TTF1, and PAX2; estrogen receptor was very focally and weakly positive; progesterone receptor was negative; p53 immunoreactivity was completely absent.
  • Targeted sequencing revealed KRAS p.G12D (activating) and TP53 p.E286* (truncating) mutations, indicating a pathogenic TP53 alteration in this tumor.
  • Literature review reported that TP53 mutations are uncommon in mesonephric lesions (reported as 4.5% of vaginal/cervical MAs and 0.9% of uterine/ovarian mesonephric-like adenocarcinomas in the reviewed series).
Limitations: Single-patient case report limits generalizability.; No functional studies reported to show the biological impact of the TP53 truncating mutation in this tumor.; Literature prevalence figures are based on a review and are not from a systematic meta-analysis; potential selection or publication bias.; No treatment outcome, follow-up duration, or clinical course provided in the abstract..

Post hysterectomy mesonephric carcinoma: A case report and literature review

Journal of cancer research and therapeutics · Jan 2022 · Case report and literature review

mesonephric carcinomavaginal vault (post-hysterectomy)

This paper reports a single case of mesonephric carcinoma occurring at the post-hysterectomy vaginal vault in a 40-year-old woman who presented with a nodular vault growth and bleeding. Routine microscopy did not show the tumor's typical morphology, and immunohistochemistry was essential to reach the diagnosis. The authors state they could not find prior reports of mesonephric carcinoma arising in the post-hysterectomy vault.

Key findings
  • Mesonephric carcinoma is a rare carcinoma of the female genital tract arising from mesonephric remnants at various pelvic sites.
  • The reported case is a 40-year-old woman, previously hysterectomised, presenting with a nodular growth on the vault and bleeding per vaginum.
  • Microscopy did not show typical morphology of mesonephric carcinoma in this case.
  • Immunohistochemistry played a vital role in making the diagnosis.
  • Authors did not find previous literature reporting mesonephric carcinoma at the post-hysterectomy vault.
Limitations: Single case report (n=1).; Abstract provides no treatment, follow-up, or outcome data.; No molecular or genetic testing results reported in the abstract.; Details and methodology of the literature review are not provided in the abstract..

Clinicopathologic Characteristics of Mesonephric Adenocarcinomas and Mesonephric-like Adenocarcinomas in the Gynecologic Tract: A Multi-institutional Study

The American journal of surgical pathology · Apr 2021 · multi-institutional case series

mesonephric adenocarcinoma (uterine cervix)mesonephric-like adenocarcinoma (endometrium)mesonephric-like adenocarcinoma (ovary)

This multi-institutional study reviewed 99 well-defined cases of mesonephric and mesonephric-like adenocarcinomas of the gynecologic tract and described clinicopathologic features. Most tumors presented at an advanced stage and over half developed recurrences, which were most often distant. Five-year disease-specific survival was 74% for cervical MA, 72% for endometrial MLA, and 71% for ovarian MLA.

Reported effects: advanced stage (II to IV) presentation, MA of the cervix 60%, n=25 · advanced stage (II to IV) presentation, MLA of the endometrium 58%, n=43 · +11 more

Key findings
  • Majority presented at advanced stage (II to IV): 15/25 (60%) MA of the cervix, 25/43 (58%) MLA of the endometrium, and 7/18 (39%) MLA of the ovary.
  • Overall recurrence occurred in 46/89 (52%) of cases.
  • Recurrence rates by site: 12/24 (50%) MA of the cervix, 24/41 (59%) MLA of the endometrium, and 10/24 (42%) MLA of the ovary.
  • When recurrence occurred, it was most commonly distant: 9/12 (75%) MA of the cervix, 22/24 (92%) MLA of the endometrium, and 5/9 (56%) MLA of the ovary.
  • Five-year disease-specific survival was 74% (n=26) for MA of the cervix, 72% (n=43) for MLA of the endometrium, and 71% (n=23) for MLA of the ovary.
  • The authors conclude mesonephric neoplasms are a clinically aggressive group with a predilection for pulmonary recurrence.
Limitations: Observational case series design with potential selection bias inherent to retrospective multi-institutional cohorts.; Subgroup sample sizes are small for some analyses (for example ovarian MLA denominators of 18-24 cases), limiting precision.; Abstract does not report treatment details, follow-up duration, or statistical analyses.; No control or comparator group reported..

What the research shows for Mesonephric Adenocarcinoma

A plain-language summary of the reviewed studies OncoForge tracks for Mesonephric Adenocarcinoma. It reports what those studies described, not a claim that any compound or therapy helps or harms Mesonephric Adenocarcinoma. Most of this evidence is early, and findings often conflict.

  • These studies are descriptive analyses of human tumor samples and case series rather than therapeutic trials.
  • A multi‑institutional review of 99 well‑defined mesonephric and mesonephric‑like gynecologic adenocarcinomas reported that most tumors presented at advanced stage and that over half of patients developed recurrences.
  • Immunohistochemical profiling in a study of 48 mesonephric and mesonephric‑like tumors found Napsin‑A positivity in about 35% of cases, typically focal and involving a minority of tumor cells.
  • A small case series (six tumors) arising in the urinary tract reported consistent PAX8 expression and a luminal pattern of CD10 staining and provided limited molecular characterization.
  • Overall, biomarker expression patterns varied across cases and studies, and findings are based on small series and retrospective pathology cohorts.

Supportive & alternative options discussed

  • Exercise / prehabilitation: Also discussed as a supportive option for people with gynecologic cancers to help maintain fitness and quality of life; these studies did not evaluate exercise.
  • Mind–body (MBSR / CBT): Also discussed as a supportive option (stress reduction, coping) in gynecologic oncology care; these studies did not examine mind–body interventions.
  • Acupuncture: Also discussed as a supportive option for symptom control (e.g., pain, nausea) in gynecologic cancers; these pathology- and biomarker-focused studies did not assess acupuncture.
  • Mistletoe (VAE): Also discussed in some regions as a complementary therapy in cancer care, but these studies did not address mistletoe or similar complementary treatments.

What we don’t know yet

  • These studies do not establish effective systemic or local therapies for mesonephric or mesonephric‑like adenocarcinomas.
  • The prognostic significance and therapeutic relevance of reported biomarkers (e.g., Napsin‑A, PAX8, CD10) remain unclear.
  • There are no prospective clinical trials reported here to define standard treatment approaches, optimal sequencing, or response rates.
  • Optimal staging, surveillance strategies, and factors predicting recurrence or long‑term survival are not defined by these reports.
  • Molecular drivers that could be targeted therapeutically and the prevalence of actionable mutations were not comprehensively characterized in these studies.
The evidence consists of retrospective case series and pathology/biomarker studies on human tumor samples; it is descriptive and early, and does not provide data on treatment efficacy or clinical outcomes from interventions.
