Adult soft tissue Ewing sarcoma or primitive neuroectodermal tumors: predictors of survival?
BACKGROUND Ewing sarcoma (ES) is the second most common primary osseous malignancy in childhood and adolescence. The improvement in survival is primarily associated with the combination of surgery and chemotherapy. HYPOTHESIS Little is known about the outcome of adults with soft tissue ES or primitive neuroectodermal tumors (PNET). Certain prognostic factors from soft tissue sarcomas (tumor s...
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 کاملMalignant Peripheral Nerve Sheath Tumors Masking as Ewing Sarcoma/Primitive Neuroectodermal Tumors
Malignant peripheral nerve tumors, a small subset of soft tissue sarcomas, provide a unique diagnostic challenge. Although they may arise from peripheral nerves or from cells associated with nerve sheaths, malignant peripheral nerve tumors often present with diverse immunohistochemical features similar to those of other tumors. These features make MPNSTs difficult to diagnose and classify. We p...
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...
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...
