Radiation-Induced Supratentorial Primitive Neuroectodermal Tumor after Treatment for Non-Hodgkin's Lymphoma.

Secondary, radiation-induced, supratentorial primitive neuroectodermal tumors (PNETs) are extremely rare entities which may present in survivors of childhood cancers after central nervous system radiation. These lesions have been described after a number of pediatric cancers and demonstrate unique treatment problems and an accelerated clinical course compared to primary PNETs. We present a case of a sixteen year old male with a history of non-Hodgkin's lymphoma who presented with a radiation-induced PNET, and describe our treatment for this lesion. These secondary, radiation-induced tumors increase in significance as the survival of childhood malignancy increases in West Virginia.
