A rare ovarian hilus cell tumour accompanying bilateral serous cystadenomas: report of a case

Abstract

Abstract Background Hilus cell tumours is considered an uncommon branch of androgen producing neoplasms that accounts for < 5% of all ovarian tumours. They are mostly benign and have characteristic gross and microscopic features. Here we present the first case of a hilus cell tumour in association with bilateral serous cystadenomas. Case presentation A 65-year-old lady with no symptoms of virilization, presented with postmenopausal dysfunctional uterine bleeding and radiological investigations revealing bilateral ovarian cysts that required a total abdominal hysterectomy with bilateral salpingo-oophorectomy. Gross and microscopic evaluation confirmed the diagnosis of hilus cell tumour associated with bilateral serous cystadenomas. Conclusions This was the first case of hilus cell tumour in association with bilateral serous cystadenomas of the ovaries. Although, majority of hilus cell tumours that have been reported in the literature were benign, further studies are required to determine the behavior of the disease.
