title: [Hemorrhagic cyst of the cavum tunica vaginalis testis: a case report].
abstract: The patient, an eight-year-old boy, visited our clinic with the chief complaint of right painful scrotal swelling persisting for two days. A scrotal puncture yielded 9 ml of bloody fluid. Afterwards a small cystic mass was detected near the epididymal head on palpation and by ultrasonography. Laboratory test results including bleeding tendency were normal. A pedunculated red cystic mass originating from the parietal lamina of the tunica vaginalis testis was found on emergency operation. Histological examinations revealed hemorrhagic cyst of the tunica vaginalis testis with no malignancy.
