Abstract

Carcinosarcoma is an uncommon malignant biphasic tumor that accounts for less than 1% of all lung cancers. It is defined by coexisting histologic elements of carcinomatous and sarcomatous components. We report two cases of carcinosarcoma in a 68-year-old patient and a 78-year-old patient explored for lung masses. Macroscopically, the resected tumors were 7 and 10 cm in diameter. Histologically, they consisted in adenosquamous carcinoma with osteosarcoma in one case and adenocarcinoma with chondrosarcoma in the other case.
