PRIMITIVE BLASTOMA PERIPHERAL PRIMITIVE NEUROECTODERMAL TUMOR OF THE MANDIBLE
INTERNATIONAL JOURNAL OF SCIENTIFIC RESEARCH, 2022Peripheral primitive neuroectodermal tumors (pPNET) are high-grade malignant tumors seen in the early age group {5-25 year}, primarily affecting long bones of extremities afterwards the pelvis, ribs and vertebrae. pPNET in the mandible (head & neck) accounts for only 2% of the reported cases.

Peripheral Primitive Neuroectodermal Tumor After Radiotherapy
Clinical Orthopaedics & Related Research, 2003A 41-year-old man had a peripheral neuroectodermal tumor develop at the distal third of the fibula 4 years after radiotherapy for relapsed villonodular synovitis. This type of sarcoma usually is classified into the heterogeneic group of small round-cell bone tumors as a subdivision of Ewing's sarcomas.

Peripheral Primitive Neuroectodermal Tumors of the Head and Neck
Archives of Otolaryngology - Head and Neck Surgery, 1995Primitive 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 ...

Ewingʼs sarcoma and peripheral primitive neuroectodermal tumor
Current Opinion in Oncology, 1994Disease-free survival for patients with small sarcomas of bone has been impressively improved with the use of intensive combination chemotherapy and safe local control with surgery or radiation. The ability of monoclonal antibodies to recognize different antigens has allowed new insights into the histogenesis and has distinguished a neural variant now ...

Strahlentherapie und Onkologie, 2013
Intracranial peripheral primitive neuroectodermal tumors (P-PNET) are extremely rare. They can be easily misdiagnosed as central nervous system primitive neuroectodermal tumors (CNS-PNET) or meningiomas. Little is known about the optimal treatment and prognosis of these tumors.We evaluated the treatment and outcome of 17 patients with intracranial ...

Unusual Presentation of Peripheral Primitive Neuroectodermal Tumor of the Maxilla
Journal of Craniofacial Surgery, 2010The peripheral primitive neuroectodermal tumor (pPNET) is a rare and highly malignant soft tissue neoplasm in children and young adults. Fewer than 10 reported cases of pPNET of maxilla are available in the English literature. A 28-year-old woman was presented with the pPNET of the maxilla and metastasis.

Ewing's Sarcoma/Peripheral Primitive Neuroectodermal Tumors in Bronchus
The American Journal of the Medical Sciences, 2019Ewing 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

Peripheral Primitive Neuroectodermal Tumor: Challenge for Multimodal Treatment
World Journal of Surgery, 2001The primitive neuroectodermal tumor (PNET) is an extremely aggressive soft tissue neoplasm that occurs in children and adolescents. We retrospectively reviewed our therapeutic experience with a multidisciplinary approach, combining surgery, chemotherapy, and radiation therapy.
