title: [A case of infantile Sertoli cell tumor].
abstract: A case of infantile Sertoli cell tumor of the testis is presented. A 2-year-old child visited our hospital with the complaint of painless swelling of the left scrotal content. A solid tumor was demonstrated in the left testis by scrotal echography. Physical and laboratory examinations were within normal limits and alpha-fetoprotein and beta-HCG were not elevated. The left testis was removed. The tumor sized 3.0 x 3.0 x 2.2 cm and weighted 14.5 g. Pathohistological diagnosis was benign Sertoli cell tumor. Tumor cells were vimentin positive and TM-1 reactive antigen positive and revealed electronmicroscopically some features of Sertoli cells such as intermediated microfilament, rich lysosomes and interdigitation between adjacent cells. The patient was well with no evidence of diseases one and a half years after the operation.
