Female Adnexal Tumor of Wolffian Origin Presenting as Paratubal / Broad Ligament Masses: A Case Report

Introduction: A female adnexal tumor of probable Wolffian origin (FATWO) is a rare type of gynecological tumor that is difficult to diagnose based on laboratory and radiologic studies. Although FATWO is considered a benign tumor, recurrence and metastasis have been reported. Currently, there is no best surgical and surveillance approach for FATWO. We presented two Wolffian tumors as paratubal / broad ligament masses.Case Presentation: This is a report of a 32-year-old woman with vaginal discharge and incidentally pelvic mass diagnosis who underwent conservative surgery with a frozen section based on the Wolffian duct tumor. Immunohistochemically, the results confirmed FATWO. The patient was free of recurrence 20 months after conservative surgery.Conclusions: Although FATWO has benign behavior, some types of this tumor have malignant features, and there is no clear recommendation regarding optimal treatment and surveillance of FATWO. Therefore, based on the literature, pathologists are recommended to utilize a wide array of immunohistochemical stainings to offer appropriate diagnosis and optimal surgery to patients. Moreover, patients should be followed up for a long-term period until we have enough knowledge in the field.
