title: [Testicular mature teratoma with onset during childhood and removed 40 years later: a case report].
abstract: A 56-year-old man presented with a painless mass in the left scrotum. The mass was first noticed when he was a junior high school student,and it had been left for about 40 years. The intrascrotal tumor of 7 cm in diameter was elastic soft and smooth. The serum levels of α -fetoprotein, β -human chorionic gonadotropin and lactate dehydrogenase were within each individual normal range. He was diagnosed as having a left testicular tumor (cT1N0M0) and underwent left high orchiectomy. Histopathological diagnosis was mature teratoma without any malignant germ cell components. No evidence of recurrence has been observed for 4 years after the operation.
