Abstract
Pediatric testis tumors are relatively rare compared with testis tumors occurring postpubertally and with other pediatric urologic tumors, such as Wilms’ tumor. The incidence of testis tumors in children is 0.5–2.0 per 100,000 children, accounting for only 1–2 % of all pediatric tumors. Testis tumors are classified by the putative cell of origin. Those arising from germ cells include yolk sac tumors (YSTs), teratomas, and epidermoid cysts. Stromal tumors include juvenile granulosa cell tumors, Leydig cell tumors, Sertoli cell tumors, and mixed or undifferentiated stromal tumors. Gonadoblastomas contain both germ cell and stromal elements. Secondary tumors rarely affect the testis, although testicular involvement with acute lymphoblastic/lymphocytic leukemia (ALL) is an important exception. By far the most common testis tumors in children are teratomas which are benign and YSTs which are malignant.
