title: Rare presentation of peripheral primitive neuroectodermal tumor in the maxilla and mandible: A report of two cases.
abstract: Peripheral primitive neuroectodermal tumor (pPNET) is a rare and highly malignant undifferentiated tumor, which presents in infants and young adults. pPNETs in the head and neck region are uncommon and have a varying incidence of occurrence. Peripheral PNETs of the maxilla and mandible are particularly rare. At present, only 16 cases of pPNET of the maxilla and 13 cases of pPNET of the mandible have been reported. The present study describes a case of pPNET of the maxilla in a 16-year-old male and a case of pPNET of the mandible in another 16-year-old male. The present study reports the radiological findings and the clinical courses of the two patients.
