Peripheral Primitive Neuroectodermal Tumors of the Head and Neck

Archives of Otolaryngology - Head and Neck Surgery, 1995
Primitive neuroectodermal tumor is a malignant small round cell tumor of neuroectodermal origin. The occurrence of these tumors in the head and neck is rare. Our objective is to document the frequency of presentation, methods of diagnosis, and forms of treatment used to combat primitive neuroectodermal tumors in the head and neck.Retrospective chart ...

The American Journal of the Medical Sciences, 2019
Ewing sarcoma/peripheral primitive neuroectodermal tumors (ES/pPNET), a member of the Ewing sarcoma family of tumors, is a malignant soft tissue tumor with small undifferentiated neuroectodermal cells. Primary trachea-bronchial ES/pPNET is very rare. The most common pulmonary ES is due to a metastasis. We describe a case of ES/pPNET which originated in

Malignant peripheral primitive neuroectodermal tumor (PNET) of the kidney

Medical and Pediatric Oncology, 1994
AbstractWe describe a 61‐year‐old patient with primitive neuroectodermal tumor (PNET) arising from the kidney. Despite intensive treatment including surgery, combination chemotherapy and radiotherapy, rapid progression of the tumor was encountered and the patient died within six months with widespread disease.
