Primary 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...
متن کاملEwing 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 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 کاملMultiple Ewing Sarcoma/Primitive Neuroectodermal Tumors in the Mediastinum
Ewing sarcoma/primitive neuroectodermal tumors (ES/PNET) are high-grade malignant neoplasms. These malignancies present very rare tumors of thoracopulmonary area and even rarer in the mediastinum. In our knowledge, ES/PNET presented with multiple mediastinal masses has not been reported previously. We experienced a case of a 42-year-old man presented with gradual onset of left-side pleuritic ch...
متن کاملCytokeratin immunoreactivity in Ewing sarcoma/ primitive neuroectodermal tumour.
Ewing sarcoma (ES)/ primitive neuroectodermal tumour (PNET) is an aggressive malignant neoplasm affecting mainly children and young adults. The tumour is included with other primitive neoplasms under the category of small round cell tumour. Cytokeratin expression in ES/PNET has been described in sporadic case reports as well as a few systemic series. We studied this feature in Malaysian patient...
