A Rare Ovarian Alliance: A Case Report on Coexistence of Benign Brenner Tumour and Mucinous Cystadenoma of the Ovary

Abstract

Brenner tumour of the ovary is a rare epithelial neoplasm accounting for approximately 2% of all ovarian tumours, most commonly seen in postmenopausal women and generally benign in nature. The coexistence of Brenner tumour with mucinous cystadenoma is distinctly uncommon, posing diagnostic and therapeutic challenges. We present the case of a 53-year-old postmenopausal woman with abdominal pain and altered bowel habits, ultimately diagnosed with a benign Brenner tumour coexisting with mucinous cystadenoma following surgical excision. This case highlights the enigmatic relationship between these tumours and underlines the importance of comprehensive histopathological evaluation and tailored surgical management.
