Ewing sarcoma/primitive neuroectodermal tumor arising in the adrenal gland.
Ewing sarcoma (ES)/primitive neuroectodermal tumor (PNET) is a malignant small round blue cell neoplasm of presumed neuroectodermal origin that affects bones and soft tissue in children and young adults. Nearly 80% of the patients are younger than 20 years. The tumor cells characteristically express CD99 (MIC2 antigen), a glycoprotein localized on cell membrane. The defining feature of ES/PNET ...
متن کاملPeripheral Primitive Neuroectodermal Tumor of the Pelvis
The primitive neuroectodermal tumor (PNET) belongs to a group of highly malignant tumors and is composed of small round cells of a neuroectodermal origin. Categorized in the same tumor family as Ewing sarcoma, the PNET is most likely to occur in bones and soft tissues. However, a small number of PNET cases arising in the pelvis have been reported as well. We present three cases of pelvic PNET: ...
متن کاملEwing sarcoma/peripheral primitive neuroectodermal tumor of the kidney: report of two cases
Ewing sarcoma/peripheral primitive neuroectodermal tumor (ES/pPNET) arising in the kidney is very rare, and only a few cases have been reported. Here we present two cases of renal ES/pPNET with different prognosis. Both patients underwent radical nephrectomy. One patient had complex EWSR1 gene chromosome translocation, high Ki-67 proliferative index and died of metastatic disease 2 months after...
متن کاملPrimitive Neuroectodermal Tumor/Ewing Sarcoma Presenting with Pulmonary Nodular Lesions
Primitive neuroectodermal tumors (PNETs) and Ewing sarcoma (EWS) belong to the same family of malignant, small, round cell neoplasms of soft tissue or bone origin. EWS-PNETs that arise in the lung parenchyma involvement are extremely rare in adults. A case of a 32-year-old male presenting with chest pain and diffuse pulmonary nodules on chest X-ray and diagnosed with Ewing sarcoma-PNETs will be...
متن کاملPrimary Ewing Sarcoma/Primitive Neuroectodermal Tumor of the Stomach
Ewing sarcoma/primitive neuroectodermal tumor (ES/PNET) is a tumor of small round cells arising in skeletal tissues. These tumors rarely arise in the stomach. We present a 31-year-old healthy female patient who was admitted to our surgical ward due to upper gastrointestinal hemorrhage. Upper endoscopy revealed a large ulcerated bleeding mass originating from the lesser curvature. Biopsy reveale...
