Peripubertal Presentation of Metastatic Testicular Mixed, Nonseminomatous Germ Cell Tumor.

Testicular tumors are relatively rare in children and those in prepubertal children tend to present with different histological types and behaviors than their postpubertal counterparts. The majority of these pre- and peripubertal testicular tumors tend to be benign and those that are malignant, tend to present at low stages, not generally requiring systemic treatment. Here we present a rare case of a peri-pubertal, mixed nonseminomatous germ cell tumor of the testes which was found to be widely metastatic at presentation, classifying as poor risk disease.
