[Pulmonary sarcomatoid carcinoma: Clinical and prognostic characteristics, a case report].

Sarcomatoid carcinoma is a rare malignancy in the family of non-small-cell lung cancer. They belong to a mixed group of poorly differenciated neoplasia, including sarcomatous cells or sarcomatoid-like cells with giant or spindle cells. We report the case of a 69-year-old man with sarcomatoid carcinoma. We describe the main characteristics of these tumors. Diagnosis is frequently delayed and lesions are locally advanced. The prognostic is poorer than other non-small-cell lung cancer. Chemotherapy is often not efficient.
