Endobronchial Sarcomatoid Carcinoma of the Lung: A Case Report

ABSTRACT

Sarcomatoid carcinomas of the lung are rare malignant biphasic tumors composed of carcinomatous and sarcomatous components. We report a case of endobronchial sarcomatoid carcinoma in a 56-year-old man with a history of smoking, in whom the tumor was an endobronchial mass arising from the superior segmental bronchus of the left lower lobe and protruding against the main bronchus without parenchymal invasion. The patient underwent left pneumonectomy but four months later died of mesenteric sarcomatous metastasis.
