Abstract

Sarcomatoid carcinomas of the lung are rare malignant biphasic tumors, which contain both a malignant epithelial component and a sarcomatoid component. The majority of patients are men and the mean age of onset is 60 years at the time of diagnosis. A metastasis to the regional lymph nodes and to distant organs is common. The clinical course of patients with this neoplasm is aggressive, with an overall 5-year survival rate approximating 20%. A sarcomatoid carcinoma of the lung is often observed in the large bronchi and peripheral lung field than in the trachea, and the clinical manifestations are related to their specific location. We report a case of sarcomatoid carcinoma of the lung in a 79-year-old man who presented with dyspnea on exertion.

Key Words: Sarcomatoid carcinoma, Lung malignancy, Biphasic tumor
