Brenner tumor of the testis: A case report and review of the literature

Brenner tumor is a rare type tumor, which mainly develops in the ovaries and rarely in the adnexal region and urinary system. To the best of our knowledge, only 5 cases of testicular Brenner tumor have been reported to date. In this report, we present the case of a 55-year-old patient who noted a swelling of the right scrotum for ~20 days. The clinical suspicion was an epididymal cyst. However, following surgical resection and subsequent pathological examination, the mass was diagnosed as a testicular Brenner tumor. A supplementary review of previously published cases and literature is also presented. The aim of this report is to help elucidate this disease and reduce the rate of clinical and pathological misdiagnosis.
