Ewing's sarcoma of the lung: A rare case.

The Ewing's sarcoma family of tumors (ESFT) incorporates both the wellrecognized primary bone and the extraskeletal soft tissue sarcomas. Primitive neuroectodermal tumors (PNET) and ESFT have a similar neural phenotype and can be considered in the same entity. Here, we will present 28 years old patient with Ewing Sarcoma. Patient was admited chest pain. Chest radiograph showed a suspicious lesion in the left paracardiac area. Computed tomography (CT) scan and positron emission tomography (PET)/CT result were compatible with malignant tumor. The patient was underwent surgical resection as the bronchoscopic result couldn't a malignant finding and pathological finding was detected as Ewing's sarcoma. Ewing's sarcoma should be considered in patients who are very fast growing in the lungs, are properly confined and suspected of malignancy in FDG-PET/CT.
