• Primary Ewing sarcoma of the respiratory system (trachea, bronchus and the pulmonary parenchyma) are rare tumors. • Bronchial Ewing sarcoma may be managed safely with sleeve resection and lung preservation. • Adjuvant therapy may not be needed if the tumor can be resected safely with negative margins. Primary bronchial Ewing sarcoma (ES) is a rare endobronchial tumor. A 65-year-old male presented with six-month history of progressive shortness of breath. Flexible bronchoscopy showed an endobronchial polypoid tumor in the left main stem bronchus about 2 cm from the carina. The tumor was resected by a left bronchial sleeve resection using a right postero-lateral thoracotomy approach. Pathology showed complete tumor resection with negative margins. The morphological and immune-phenotypical features of the resected specimen were compatible with ES. He had an uneventful post-operative recovery. He did not receive adjuvant radiation or chemotherapy and remains disease free at 9 months follow up. A review of the literature identified six other cases of primary bronchial ES. In addition, there were three reported cases of primary ES involving the trachea and thirteen involving the lung parenchyma. Bronchial ES appeared to have a relatively better prognosis than ES involving the trachea or the lung. Our case demonstrates that primary bronchial ES may be treated safely with limited resection, lung preservation and without the need for adjuvant therapy if negative margins can be achieved. Sleeve resection without adjuvant therapy may be a safe treatment option for primary bronchial ES. [ABSTRACT FROM AUTHOR] |
