RESUMO
ABSTRACT: Primary adenocarcinoma of the seminal vesicles is a rare tumor. Congenital seminal vesicle cysts are often associated with unilateral renal dysgenesis or agenesis (Zinner syndrome). Zinner syndrome is a rare congenital malformation represented by a group of characteristics: ipsilateral renal agenesis, ejaculatory duct obstruction, and seminal vesicle cyst. There have been 214 cases in the literature with abdominal pain and lower urinary tract symptoms as the most common presentation. Most cases are diagnosed incidentally. We report a case of a 39-year-old male presenting with recurrent hematuria for 12 years, diagnosed as metastatic primary clear cell adenocarcinoma of seminal vesicle with Zinner syndrome. He was managed symptomatically with radiation therapy, hormonal therapy, and palliative chemotherapy. He is living with a well-controlled disease at present.
