Primitive neuroectodermal tumor transformation of testicular teratoma

Abstract

Malignant transformation of teratoma develops in a small subset of testis cancer patients. Primitive neuroectodermal tumor represents a highly malignant component of testicular germ cell tumors. It is a rare clinical entity which is characterized by a high risk of disease progression and death. Surgical resection plus chemotherapy appears to be the therapy of choice.
