Acute scrotum due to arterial bleeding mimicking non-seminomatous germ cell tumor.

Men with testicular tumors usually present with painless increase in testis size incidentally noticed by the patient. We report a case of a young patient presenting as an emergency with acute onset of massive right-sided testicular pain without previous injury. After physical examination testicular torsion could not be excluded. Ultrasound examination of the testis was suspicious for testicular tumor. Surgical exploration of the right testis by inguinal approach was performed revealing subcapsular arterial bleeding due to a small nonseminomatous germ cell tumor non-palpable on clinical examination.
