Abstract:

Ovarian borderline Brenner tumor is a rare tumor of the ovary. The clinical symptoms and auxiliary examination usually have no special manifestation. Postoperative histopathology combined with immunohistochemistry is needed to confirm the diagnosis. A 46-year-old female patient was diagnosed as ovarian borderline Brenner tumor by postoperative pathological examination after surgery due to a 1-week left adnexal mass found in physical examination. The clinical features, diagnosis, differential diagnosis, treatment and prognosis were analyzed. The data of this case, combined with literature review, can help us to increase the understanding and to reduce the misdiagnosis rate of ovarian borderline Brenner tumor.
