We present the case of a 51-year-old male with Zinner syndrome, which is a rare disease, resulting from an abnormal evolution of the mesonephric (Wolffian) duct. It consists in cystic dilations of one seminal vesicle and/or ejaculatory duct and ipsilateral renal agenesis. It leads to symptoms related to urination, ejaculation, even infertility, and to low-abdomen and perineal pain. The diagnosis is set by ultrasonography, CT scan and, mainly, MRI. Usually it is treated conservatively, but certain cases require surgery, nowadays minimally invasive.

Mesonephric-like adenocarcinoma is a new class of rare subtypes of the female reproductive system. Its clinical symptoms are similar to other types of ovarian tumors. The diagnosis is based on pathological and immunohistochemical methods. The main treatment option is surgery combined with chemotherapy. Few cases have been reported at home and abroad. We reported a case of a 45-year-old woman with a cystic solid mass in the left adnexa. The postoperative pathological diagnosis was mesonephric-like adenocarcinoma of the left ovary and mature cystic teratoma (partial infiltration of the small intestine). This case had no specific clinical symptoms. Immunohistochemical findings showed positive results of GATA3, TTF1, CD10, ER, and PR. Paclitaxel and carboplatin chemotherapy were given after the operation. Currently, no specific criteria are available for diagnosis and treatment of the disease. This article aims to improve the understanding of clinicians in this disease and create a basis for clinical diagnosis and treatment.

Review
BACKGROUND
Mesonephric adenocarcinoma (MA) of the vagina is a rare tumor that arises from mesonephric remnants (Wolffian) in the female genital tract. It is a neoplasm with no significant evidence about its diagnosis, treatment, follow-up and prognosis.
METHODS
Systematic research of the literature was conducted in Scopus, PubMed/MEDLINE, ScienceDirect and the Cochrane Library, including observational prospective and retrospective studies, case series and case reports. We collected data regarding studies related to diagnosis and treatment options evaluating the following aspects: study design, population, treatment type, rate of surgical complications and fertility outcome. We further included a case report of laparoscopic management of MA with pictorial assays.
RESULTS
Thirteen cases of MA of the vagina are available in the literature, including our case report. The median age at diagnosis was 52 years old; the majority of patients reported vaginal bleeding as a symptom (38%); and ultrasound, followed by a magnetic resonance and CT scan were the diagnostic tools most used. In 54% of the cases, a surgical biopsy was performed, and 92% of the patients underwent upfront surgery with an open access or vaginal resection except one case fully managed by minimally invasive surgery. Most of the patients (68%) received adjuvant treatment with chemotherapy or radiotherapy or a combination of them. The mean follow-up period was 6 years.
CONCLUSIONS
Despite the rarity of this cancer and bizarre location, a minimally invasive approach seems feasible after multidisciplinary evaluation. According to the rarity of this tumor, any future case and follow-up data must be reported in the literature in order to enlarge the knowledge about it.

Herlyn-Werner-Wunderlich syndrome is a rare complex congenital anomaly of the urogenital tract involving Mullerian ducts and mesonephric ducts. It is also called OHVIRA syndrome (Obstructed Hemivagina and Ipsilateral Renal agenesis). It is characterized by a triad of uterus didelphys, obstructed hemivagina and ipsilateral renal agenesis. Patients usually present after menarche with pelvic pain, dysmenorrhea, mass, and rarely with primary infertility in later years. We report a case of a multiparous female who presented to the hospital with pain in lower abdomen for the past 2 months and acute retention of urine for 1 day. This is an atypical presentation in a multiparous female that has been described in a single case report so far. Intravenous pyelogram and MRI of the patient revealed uterine didelphys, obstructed right hemivagina causing hematohemicolpos and right renal agenesis. Thorough knowledge of imaging features can enable a radiologist to make a correct diagnosis even in an atypical presentation.

Mesonephric-like adenocarcinoma (MLA) arising in the ovary is a rare malignant tumor of the female genital tract. Although the clinicopathological and molecular characteristics of uterine MLA have been accumulated, those of ovarian MLA have not been firmly clarified. In this study, we investigated the clinicopathological, immunohistochemical, and genetic features of five ovarian MLAs. A review of electronic medical records and pathology slides, immunostaining, and targeted sequencing was performed. On imaging, ovarian MLA presented as either a mixed solid and cystic mass or a purely solid mass. One, three, and one patient were diagnosed as having FIGO stage IA, IC, and II MLA, respectively. Four patients with stage IC-II tumor underwent post-operative adjuvant chemotherapy. Three of the four patients whose follow-up information was available did not experience recurrence. In contrast, the remaining patient with stage IA tumor who did not receive any adjuvant treatment developed multiple metastatic recurrences at post-operative 13 months. Histologically, ovarian MLAs characteristically displayed architectural diversity, compactly aggregated small tubules, and eosinophilic intraluminal secretions. Four tumors were found to be associated with endometriotic cysts. Two cases showed some areas of high-grade nuclear atypia, brisk mitotic activity, and necrosis. Immunohistochemically, all cases showed positive immunoreactivities for at least three of the four examined mesonephric markers (GATA3, PAX2, TTF1, and CD10), lack of WT1 expression, non-diffuse p16 immunoreactivity, and wild-type p53 immunostaining pattern. Targeted sequencing analysis revealed that all four examined cases harbored pathogenic mutations: p.G12V (2/4); p.G12D (1/4); and p.G12C (1/4). In addition, we reviewed the previous literature reporting 60 cases of ovarian MLA. Our findings corroborate those of the previous data regarding the clinical presentation, histological features, immunophenotypes, and molecular alterations. Our observations should encourage pathologists to recognize and accurately diagnose this rare but distinct entity.

Leydig cells (LCs) are the major androgen-producing cells in the testis. They arise from steroidogenic progenitors (SPs), whose origins, maintenance, and differentiation dynamics remain largely unknown. Single-cell transcriptomics reveal that the mouse steroidogenic lineage is specified as early as embryonic day 12.5 (E12.5) and has a dual mesonephric and coelomic origin. SPs specifically express the Wnt5a gene and evolve rapidly. At E12.5 and E13.5, they give rise first to an intermediate population of pre-LCs, and finally to fetal LCs. At E16.5, SPs possess the characteristics of the dormant progenitors at the origin of adult LCs and are also transcriptionally closely related to peritubular myoid cells (PMCs). In agreement with our in silico analysis, in vivo lineage tracing indicates that Wnt5a-expressing cells are bona fide progenitors of PMCs as well as fetal and adult LCs, contributing to most of the LCs present in the fetal and adult testis.

Review
OBJECTIVES
Endometriosis originating in mesonephric cyst is unusual and with unknown prevalence. Endometriotic lesion in vestigial remnant of wolffian duct (mesonephric cyst) is exceptional. In the extended literature review only three cases have been reported in animal studies, and our case reported here is the first in human beings. We present a case of mesonephric cyst endometrioma in a 37-year-old patient who was referred for severe dysmenorrhea, long duration pelvic and back pain, subfertility, severe dyspareunia, and groin discomfort. The patient underwent laparoscopic removal and we performed a literature review to gain insight about the origin and surgical management of an atypical site endometriosis.
METHODS AND PROCEDURES
Case report presentation rests on information obtained from the patient database. We performed the literature review using a Medline search with the keywords: mesonephric cyst endometriosis, atypical location of endometriosis in vestigial remnant in wolffian duct, and Gartner duct cyst endometrioma.
RESULTS
On physical examination, fullness and tenderness in left adnexa and lateral vaginal wall fullness on left side with restricted mobility of uterus was noted. Based on the examination and imaging the left ovarian cyst and mesonephric cyst were suspected. Surgical exploration revealed the left hemorrhagic cyst with deep infiltrating endometriosis involving left ureter and left uterosacral ligament with mesonephric cyst endometriosis. The review of literature revealed three cases where ectopic endometrial tissue in mesonephric cyst remnant was found in female dogs.
CONCLUSION
Mesonephric cyst endometrioma, although rare, can be a representative of extensive endometriosis. This case highlights an importance of careful clinical examination, correlation of patient symptoms with examination and imaging, and successful laparoscopic management of an atypical location endometriotic lesions. We completed the literature review on successful surgical management of such cases.

Archives of Pathology & Laboratory... Jan 2022Female adnexal tumor of probable Wolffian origin (FATWO) often is a diagnostic challenge given its rarity, histologic heterogeneity, and lack of specific immunoprofile.
CONTEXT.—
Female adnexal tumor of probable Wolffian origin (FATWO) often is a diagnostic challenge given its rarity, histologic heterogeneity, and lack of specific immunoprofile.
OBJECTIVE.—
To further understand the clinicopathologic and immunohistochemical features of this rare entity.
DESIGN.—
We studied the clinical, morphologic, and immunohistochemical features of a cohort of 11 FATWO cases from our institute.
RESULTS.—
Patients' age ranged from 25 to 76 years (mean, 55 years). Tumor size ranged from 0.5 to 18 cm (mean, 2.7 cm). Histopathologically, most tumors presented with low-grade cytologic features with low mitotic activity and lack of necrosis. Three main growth patterns were appreciated: solid, tubular, and sievelike patterns. Higher-grade nuclear atypia, increased mitotic activity, and focal necrosis were seen in 2 cases. These 2 cases were clinically considered malignant FATWO mainly because of their extra-adnexal involvement. Immunohistochemical studies found that tumor cells were positive for CD10 (11 of 11, 100%), AE1/3 (8 of 8, 100%), CAM 5.2 (4 of 5, 80%), and cytokeratin 7 (CK7; 7 of 10, 70%), and focally positive for calretinin (4 of 10, 40%), inhibin (4 of 10, 40%), epithelial membrane antigen (EMA; 3 of 9, 33%), and steroidogenic factor-1 (SF-1; 2 of 8, 25%). Lack of immunoreactivity to PAX8 and GATA3 in almost all cases indicates that FATWO is different from the tumors derived from the Müllerian or mesonephric origins. All patients with available follow-up had favorable prognosis.
CONCLUSION.—
The broad spectrum of clinical presentation, various morphologic features, and overlapping immunophenotype suggest that FATWO is a diagnosis of exclusion until it is further defined at the molecular and immunohistochemical levels.
