BENIGN OVARIAN BRENNER TUMOR

A CASE REPORT

Abstract

Brenner’s tumors arise from the ovarian epithelium and are classified by the Word Health organization (WHO) as benign, malignant and borderline. They are characterized by a nest of transitional cells, which resemble urothelial cells, surrounded by a fibrous stroma. They usually present themselves in patients between the fifth and seventh decade of life. Most of them are asymptomatic and discovered accidentally, through the detection of a pelvic mass on physical examination, imaging exams, laparotomy, or even in the pathological study of an oophorectomy performed for other types of tumors, with cystadenomas being more common.
