睾丸腫瘍(胎児癌)における原発巣自然退縮と考えられる1例

Abstract

An autopsy case of burned out testicular germ cell tumor in a 27-year-old man was reported. The patient complained of severe abdominal pain on the left side. Clinical examination and laparotomy established the diagnosis of retroperitoneal germ cell tumor. The testes were normal on palpation up to his death. At autopsy, however, a small red focus was found on the tunica albuginea of his left testis. Careful histological examination showed small fibrous scar containing hyalinized seminiferous tubules, hemosiderin deposits and peculiar hematoxylin-staining substances. This finding strongly suggests the spontaneous regression of the primary germ cell tumor in the testis.
