Juvenile granulosa cell tumor of the testis in a 3-month-old infant

Abstract

Juvenile granulosa cell tumor (JGCT) is a rarely diagnosed subset of benign sex cordstromal testis tumors. Although it accounts for only 1.2% of all prepubertal testis tumors, the JGCT is one of the most common congenital and infantile testicular neoplasms. In contrast to other sex cord-stromal tumors in boys and to the ovarian homologue of the JGCT, there are no clinically evident endocrine manifestations. In this article we report a case of juvenile granulosa cell tumor of the left testis in a 3- month-old infant.
