Abstract
Mesonephric lesions in the female genital tract are uncommon, with those arising from the upper tract being much less frequent than those developing in the lower tract (mesonephric hyperplasia and carcinoma). The most common upper tract lesions include rete cyst/cystadenoma and female adnexal tumour of Wolffian origin (FATWO). The integration of morphological, immunohistochemical and molecular studies on FATWOs has enabled recognition of a novel entity, the STK11 adnexal tumour, which is often associated with Peutz-Jeghers syndrome (~50%) and frequently has a salivary gland morphology but an unknown origin. Similarly, 'mesonephric-like' adenocarcinoma, an entity with striking similarities to mesonephric carcinoma but currently favoured to be of Müllerian derivation based on its association with other Müllerian tumours and molecular findings, has also been recently described, and may histologically mimic both FATWOs and STK11 adnexal tumours. In this review, we provide a historical overview of upper female genital tract mesonephric proliferations and discuss mesonephric lesions, STK11 adnexal tumour, mesonephric-like adenocarcinoma, and mimickers, the most common being endometrioid carcinoma.

Abstract
RATIONALE Female adnexal tumors of probable Wolffian origin (FATWOs) are rare gynecologic neoplasms arising from the mesonephric duct remnants. Less than 90 cases have been reported in the English literature. Although most cases of FATWO are considered benign, recurrence and metastasis may occur in very few cases during the course of the disease. Due to the small number of recurrent and metastatic FATWO cases, there are no clear recommendations regarding optimal treatment. PATIENT CONCERNS A 75-year-old postmenopausal woman, who underwent a mass excision of the right broad ligament three years ago, was found to have a right adnexal mass during a regular postoperative physical examination. DIAGNOSES Vaginal ultrasound examination revealed a cystic and solid mass approximately 3.6 × 4.4 × 3.8 cm on the right side of the uterus. Three years ago, the mass of the right broad ligament was diagnosed with FATWO in the local hospital. Following extensive immunohistochemistry analysis and after reviewing the histology slides from the primary tumor, the final diagnosis of the mass on the right side of the uterus was recurrent and metastatic FATWO. INTERVENTIONS The patient underwent laparoscopic mass excision, hysterectomy and resection of the metastatic lesion in the small intestine, and then she received 6 cycles of docetaxel and carboplatin-based chemotherapy. OUTCOMES The disease has recurred three years after the first surgery in the local hospital. After the second surgery followed by systemic chemotherapy, there is no evidence of recurrence with 24 months of follow-up till now. LESSONS FATWO is considered a benign entity. However, a few FATWOs have been shown to behave aggressively. Due to only a few reported cases, there are no comprehensive recommendations regarding the optimal clinical management of recurrent and metastatic FATWOs. Complete surgical resection followed by combination chemotherapy is considered to be the most effective therapy for recurrent and metastatic FATWOs. Chemotherapy with docetaxel plus carboplatin, which is most commonly used in malignant cases, may be effective in the treatment of recurrent and metastatic FATWOs.

Female adnexal tumors of probable Wolffian origin: morphological, immunohistochemical, and molecular analysis of 15 cases. Mod Pathol 2020; 33:734-747.

Abstract
Female adnexal tumors of probable Wolffian origin are rare and present a diagnostic challenge due to their morphological and immunohistochemical overlap with more common ovarian and broad ligament entities. We evaluated the morphological, immunohistochemical, and molecular features of 15 tumors of probable Wolffian origin. Patients ranged from 32 to 69 (mean 47) years and tumors from 1.8 to 30 (mean 10) cm. All except one arose in para-adnexal soft tissues. Follow-up was available for six patients, five of whom were alive and well, while the sixth, who had extra-adnexal disease at diagnosis, died from unrelated causes. The following patterns were noted: tubular (all tumors), solid 11/15 (73%), sieve-like 7/15 (47%), and reticular 1/15 (7%). A myxoid background was present in 3/15 (20%) of tumors and eosinophilic luminal secretions in 11/15 (73%). Most tumors (12/15, 80%) had low-grade nuclear atypia, while three showed foci with scattered high-grade atypia. Mitotic index ranged from 0 to 17 (mean 4) per ten high-power fields. Tumors were positive for pankeratin and negative for TTF-1. EMA, GATA3, and PAX8 were positive in 2/10 (20%; focal), 3/15 (20%; focal), and 1/15 (7%; focal) of tumors, respectively. CD10, SF-1, calretinin, inhibin, ER, PR, cytokeratin 7, and WT1 were variably expressed. Pathogenic mutations were rare and included STK11 (n = 3), APC (n = 1), and MBD4 (n = 1). Copy number variations were detected in the three tumors with STK11 mutations and a myxoid background. These data demonstrate that female adnexal tumors of probable Wolffian origin are morphologically and immunohistochemically diverse, but infrequently harbor pathogenic mutations. However, their lack of mutations in contrast to their mimickers may be a valuable tool in diagnostically difficult cases.

Abstract
Endometrioid carcinoma is known for its diverse morphology and may pose a diagnostic dilemma when it presents with a spindle cell component. We present a case of a 65-year-old woman with postmenopausal bleeding. Physical examination showed a mass protruding from the external cervical os. The patient underwent biopsy followed by hysterectomy. Pathologic examination showed an endometrioid endometrial carcinoma with spindle cell differentiation arising in an endometrial polyp, which raised a variety of differential diagnoses. Prior reports of this tumor type showed nonaberrant immunohistochemical expression of p16 and p53. However, this case showed p16 and p53 overexpression indicating that there is a spectrum of these tumors.

Abstract
The mesonephric (Wolffian) duct regresses in females during embryological development. Remnants of this duct may persist typically along the lateral walls of the cervix, vagina, adnexa, and uterine corpus. These mesonephric epithelia may expand into hyperplastic proliferations and rarely form neoplasms. The spectrum of morphology, immunophenotype, clinical presentation, and molecular characteristics of mesonephric lesions is reviewed, with attention to distinction from entities in the differential diagnosis.

Abstract
In view of the small number of recurrent and metastatic cases of female adnexal tumors of probable Wolffian origin (FATWO), there is a distinct lack of evidence to support recommendations regarding treatment. In the present study, a 37-year-old female was diagnosed with a left adnexal tumor and underwent a left salpingo-oophorectomy (SO). The tumor was found to arise from the left tubal fimbria and extend to the posterior leaf of the broad ligament. Pathological examination identified a number of solid, tubular and cystic architectures, with areas of hyalinization, hemorrhage and necrosis. Immunohistochemistry detected that the tumor cells were positive for cytokeratin (CK)7, vimentin, inhibin and calretinin, and negative for CK20, epithelial membrane antigen, and the estrogen and progesterone receptors. Thus, the patient was diagnosed with FATWO. Following 15 months, the patient developed recurrent tumors and subsequently underwent a total abdominal hysterectomy, a right SO and extirpation of the disseminated tumors, but with incomplete debulking. The tumor cells were immunoreactive for KIT. As there are a limited number of treatment options and few reported cases, limiting the therapy recommendations, imatinib mesylate was administered for 6 months and the tumors were temporarily stabilized for 4 months until the disease progressed. The patient underwent a further debulking surgery that did not achieve complete debulking and was subsequently administered a combination chemotherapy of paclitaxel and carboplatin. This regimen resulted in an almost complete response after 10 cycles. The tumors continued to decrease in size, and the tumors in the left side of the Douglas pouch and the right para-colic gutter were no longer detectable. To the best of our knowledge, the current study is the first to report carboplatin and paclitaxel combination therapy demonstrating a response of this degree to recurrent FATWO following the failure of imatinib treatment. However, surgical debulking remains the most effective treatment for FATWO when is it is possible. The precise role of chemotherapy, radiotherapy and molecular-targeting therapy in the treatment of recurrent or metastatic FATWO remains to be elucidated, and therefore, novel strategies to overcome this disease must be prioritized.

Abstract
Female adnexal tumors of probable Wolffian origin (FATWO) are rare tumors, which are mostly localized in the broad ligament or the mesosalpinx. They show high intratumor and intertumor variability of histological patterns (e.g. solid, tubular, cribriform and cystic) with usually unremarkable cellular and nuclear morphology and a lower mitotic rate. In general, they behave in a benign fashion but there are rare cases with malignant transformation, so that careful examination and surveillance are necessary. Differential diagnoses include Sertoli-Leydig cell tumors, metastasized endometrioid carcinoma and the FATWO-like variant of the endometrioid carcinoma of the fallopian tubes. The FATWOs express pancytokeratin, CD10, vimentin, calretinin and inhibin A. Estrogen and progesterone receptors are expressed in a minority of cases, whereas epithelial membrane antigen (EMA) is not detectable.

Abstract
This is the case report of a 38-year-old woman who presented with a mass of the right broad ligament that was diagnosed as a female adnexal tumor of probable Wollfian origin (FATWO). The patient was treated with a simple mass excision. Three years after the excision, the patient presented with uterine bleeding. A total abdominal hysterectomy was advised. Intraoperative histologic consultation showed a poorly differentiated tumor on the surface of the left ovary. After extensive immunohistochemistry analysis and after reviewing the histology slides from the primary tumor, the final diagnosis was concluded to be recurrent FATWO on the surface of the ovary. C-kit immunohistochemistry was found to be strongly positive. Polymerase chain reaction amplification of C-kit genes on exons 9, 11, 13, and 17 and of PDGFR gene on exons 12 and 18 showed no mutational changes. Owing to the limited options in treating recurrent disease and the lack of prognostic factors for recurrence or metastasis, the patient was started on 400 mg of imatinib mesylate therapy for 6 months. In addition, the patient is undergoing continuous follow-up by computed tomographic imaging every 6 months. As chemotherapy and radiation therapy for recurrent or metastatic FATWO are most often unsuccessful, a molecular targeted therapy, such as tyrosine kinase inhibitor, could be considered. However, collective data are needed from multiple centers to determine its effectiveness in these patients.

Abstract
Male adnexal tumours of Wolffian duct origin are very rare. They have variable malignant potential and surgical excision is recommended. We report the case of a 56-year-old male who presented with a swelling in the perineum thought to be a haematoma as the result of a complication of a laparoscopic inguinal hernia repair. It recurred after incision and two attempts at drainage and was then completely excised. Histology revealed the lesion to be an adnexal tumour of probable Wolffian duct origin. To our knowledge there have only been two previous cases of male adnexal tumour of Wolffian duct origin reported in the literature.

Abstract
An 87-year-old woman underwent total abdominal hysterectomy and bilateral salpingo-oophorectomy for endometrioid adenocarcinoma. At operation, a 4.5-cm partially solid and partially cystic right ovarian mass was identified. Frozen section showed a cytologically bland spindle cell proliferation reminiscent of cellular fibroma. Extensive sampling of the ovarian mass revealed a focus with the classic sieve-like pattern of a Wolffian adnexal tumor that merged with the fibroma-like appearance. The uterus showed well-differentiated, superficially invasive endometrioid adenocarcinoma arising in a background of atypical complex hyperplasia. Given the recent reports implying a therapeutic value for Gleevec (Novartis, Stein, Switzerland) (STI-571) in the treatment of Wolffian tumor of the ovary, paraffin immunostain for CD117 (c-kit) was performed that yielded negative results. Without further therapy, the patient was alive without disease 7 months after surgery. This case demonstrates the heterogeneity of Wolffian tumor of the ovary and shows how crucial sampling is in arriving at the correct diagnosis.

Abstract
Female adnexal tumors of probable wolffian origin (FATWO) are rare neoplasms believed to originate from mesonephric (wolffian) remnants. Rarity and variable location of FATWO make the diagnosis difficult. Although most cases follow a benign clinical course, approximately 10% of them either recur or metastasize and are thought to be resistant to chemoradiation therapy. In 2004, imatinib therapy, a tyrosine kinase inhibitor known to be effective against gastrointestinal stromal tumors, was reported to be effective also in a case of KIT-positive FATWO. However, c-kit gene mutations in FATWO have never been studied. Herein is reported the case of a 50-year-old Japanese woman with FATWO arising in the right paratubal site. The tumor had typical characteristics of FATWO in both morphology and immunohistochemistry. KIT protein was diffusely and weakly expressed, but DNA analysis revealed no mutational change in exon 9 or 11 of the c-kit gene. It is believed that accumulation of such genetic data of FATWO are essential from a therapeutic standpoint, although the present case had no mutation. In addition, the cytological features of this rare tumor are presented, which have not been described previously.

Abstract
BACKGROUND Female adnexal tumors of probable wolffian origin (FATWO) represent a rare gynecologic tumor and display in the majority of cases a benign behavior. CASE A 27-year-old woman underwent a laparotomy for a left adnexal mass. Pathologic examination showed a FATWO. Three years later, 1 month after a vaginal delivery, a recurrence of the disease was observed. Immunohistochemistry revealed the presence of progesterone receptors that may explain recurrence after pregnancy. CONCLUSION In light of this case, hormone dependency of FATWO may be suggested.

Abstract
Female adnexal tumors of probable wolffian origin (FATWOs) are rare tumors arising in the broad ligament from the remnants of the mesonephric duct. We report a case of recurrent disease. A 15-year-old girl who presented with a painful pelvic mass underwent a laparotomy with tumor resection. Pathology findings confirmed a FATWO. The tumor recurred within 2 years and was treated with multiple chemotherapy regimens, including a platinum-based drug, and surgery for progressive disease. The tumor was positive for c-kit oncogene (CD 117). Gleevac therapy, a tyrosine kinase inhibitor, was prescribed, and she developed severe persistent lower abdominal pain 2 months later. She underwent a hysterectomy and debulking of retroperitoneal masses. Pathology showed evidence of tumor necrosis, suggesting a possible beneficial effect, and she was recommenced on Gleevac in an effort to prevent recurrences. She is currently asymptomatic, without evidence of disease 10 months after surgery, continuing on Gleevac therapy. FATWOs are very rare tumors. Most cases are benign but have the potential to recur and metastasize. There is limited knowledge about the optimal treatment for this neoplasm. Our patient's favorable response to Gleevac therapy supports the concept of targeted molecular therapy in patients with c-kit-positive FATWO tumors.

Abstract
BACKGROUND Female adnexal tumors of probable wolffian origin are a distinctive epithelial neoplasm arising from the remnants of the mesonephric duct. Although generally considered a tumor of low malignant potential, these tumors can recur. Two cases are reported here. CASES (1) A 38-year-old G(6)P(6) Latin American woman presented with lower abdominal pain and a pelvic mass. She had a history of a total abdominal hysterectomy and bilateral salpingo-oophorectomy with a paratubal nodule found incidentally 3 years prior. The pathologic findings were consistent with a female adnexal tumor of probable wolffian origin. Imaging studies revealed significant metastatic disease throughout her abdomen and pelvis. The recurrence was confirmed at laparotomy and tumor debulking was performed. Four months later the patient suffered a second recurrence and is currently undergoing treatment with systemic therapy. (2) A 71-year-old Caucasian woman who had undergone exploratory laparotomy and tumor reductive surgery for a female adnexal tumor of probable wolffian duct origin was seen for routine evaluation 1 year after her surgery. Her computed tomography scan revealed possible evidence of recurrence. CONCLUSION Most female adnexal tumors of wolffian origin behave in a benign fashion. However, there is a potential risk of recurrence. Surgical excision by total abdominal hysterectomy and bilateral salpingo-oophorectomy at the time of diagnosis may be the best recommended mode of therapy. The role of adjuvant radiation therapy or chemotherapy remains questionable.
