Scrotal Peripheral Primitive Neuroectodermal Tumor.

The peripheral primitive neuroectodermal tumor (pPNET) is a rare malignant tumor originating from neuroectoderm that usually occurs in children or adolescent and is frequently located in the extremities, chest cavity, pelvic cavity and chest wall. We present a rare case of an 84-year-old man with a history of pPNET in the scrotal sac, to our knowledge not previously published in the literature. The presence of a large irreducible mass in the inguinal sac forced to exclude a tumor.
