Female Adnexal Tumour of Wolffian Origin: A Rare Case Report

Abstract

Female Adnexal Tumour of Wolffian Origin (FATWO) is a rare tumour occurring in adnexal region, arising from the remnants of the mesonephric duct, in places like the broad ligament, fallopian tube, ovarian hilum, peritoneum. Here the authors have reported a case of FATWO in a 47-year-old woman occurring in the wall of fallopian tube and confirmed with immunohistochemistry. Most of these tumours behave in a benign fashion but certain histological features like hypercellularity, cellular pleomorphism and nuclear atypia cause significant confusion in histopathological diagnosis. Multiple differential diagnoses were considered. After careful histopathological examination and thorough investigation with multiple immunohistochemical stains, the diagnosis was ultimately established.
