Paratesticular rhabdomyosarcoma.

Two cases of paratesticular rhabdomyosarcoma were reported. One was a 53-year-old male, who was admitted to the Hospital because of swelling of the scrotum, hemosputa, and complete left hemiplegia. Clinical diagnosis was testicular tumor with remote metastases to lung, brain, liver, and para-aortic lymph nodes. At operation, tumor of 340 g of the paratesticular appendage was removed. Pathological findings of the tumor revealed rhabdomyosarcoma of mixed pleomorphic and embryonal types. The other was a 32-year-old male, who was admitted to the Hospital because of left inguinal and scrotal masses. The patient had a history of bruise at the left inguinal region about 5 years prior to admission. An orchiectomy and an excision of the inguinal tumor were performed. Histologically, the tumor was rhabdomyosarcoma of pleomorphic type. Clinical and pathological features of this rare tumor were discussed with a review of literature.
