[Testicular cavernous hemangioma associated with intrascrotal testicular torsion: a case report].

A 22-year-old man consulted our hospital with a left intrascrotal mass and a six-day history of dull pain in the left lower abdomen. Serum levels of tumor markers were normal. Testicular ultrasonography demonstrated a heterogeneous isoechoic mass in the left testis. Computed tomography revealed a left testicular mass with high density. A diagnosis of probable testicular malignancy was made, and left radical orchiectomy was performed. Intraoperative findings indicated torsion of the left testis. The testis was necrotic and the mass including the testis was extirpated. The histopathological diagnosis was testicular cavernous hemangioma. To our knowledge, only 20 cases of cavernous hemangioma of the testis have been reported to date, and this is the first report of testicular hemangioma presenting with torsion of the testis.
