Pure Sertoli cell tumor of the right ovary managed with fertility-sparing surgery: a case report.

Sertoli cell tumors (SCTs) of the ovary are rare sex cord-stromal neoplasms. We describe a 37-year-old Ethiopian woman (G2P2) with six months of progressive lower abdominal pain but no virilization. Ultrasound revealed a solid 11 cm right adnexal mass. Hormonal profile was normal. An open fertility-sparing right salpingo-oophorectomy was performed. Histopathology confirmed a FIGO Stage IA well-differentiated pure SCT. Postoperative surveillance was conducted via clinical pelvic examinations and abdominal/pelvic ultrasounds every three months. At 12-month follow-up, there was no recurrence. This case highlights that SCTs may be hormonally inactive; histopathologic evaluation remains decisive, and fertility-preserving surgery is a safe option in early-stage lesions.
