Background: Female adnexal tumour of Wolffian origin (FATWO), a rare neoplasm arising from the female adnexa, is typically benign in nature, although recurrences and metastasis have been reported infrequently. First identified and reported in the early 1970s, less than 100 cases have been reported thus far. Case Presentation: We present a case of a 16-year-old girl with a left adnexal tumour of Wolffian origin who presented with excessive bleeding during mensuration. With no overt clinical signs, ultrasound revealed a left ovarian neoplasm which was confirmed by CT scan as a solid enhancing lesion in the left adnexa measuring 6.2 x 5 x 4.5 cm. A broad ligament mass was excised, and cytology of peritoneal fluid wash revealed no malignancy. Histomorphological examination and immunohistochemistry confirmed the diagnosis of FATWO. The postoperative course was uneventful; however, the patient was lost to follow-up. Conclusion: Due to the rarity of occurrence, asymptomatic presentation, its variable location, and its morphological diversity, the diagnosis of FATWO may present a challenge especially when the tumour arises in an ovarian location.
