An incidental finding of benign Brenner tumor in mucinous cystadenoma of ovary: a case report

Abstract

Ovarian tumors are common neoplasia in women. Ovarian carcinoma accounts for the 7 cause of mortality and morbidity in females. Surface epithelial tumors are the most common type of ovarian tumor. Mucinous tumors comprise 20% to 25% of the ovarian neoplasms. Brenner tumor of the ovary consist of 1-2% of all ovarian neoplasms and is usually benign. About 30% of Brenner tumors coexist with an ovarian mucinous neoplasm, a well-recognized combination that has been rarely reported. Accurate diagnosis and exclusion of malignancy are essential in large ovarian tumors, especially in tumors with solid components. We describe a case of an incidentally diagnosed Brenner tumor in a sizeable mucinous cystadenoma of the ovary to inform the clinicians about the co-occurrence of such a tumor so they remain vigilant in ruling out malignancy for better management as well as prognostication.
