[Renal teratoma, case report and review of the literature].

We report a case of intrarenal teratoma in a 39-year-old female patient. The clinical course after three years of follow-up has been satisfactory, finding the patient totally asymptomatic. Extragonadal teratoma occurs predominantly along the median line of the body. Intrarenal teratoma is extremely rare; however, it should be distinguished from other cystic lesions.
