The Teaching Point

Carcinosarcoma is a malignant tumor having a mixture of carcinoma and sarcoma, presenting as a solitary mass with the location and features of the epithelial component. The endobronchial proliferation of this tumor creates the appearance of "finger-in-glove" in chest radiograph. Although the CT characteristics are suggested by the epithelial component, definitive anatomopathologic diagnosis is needed for appropriate treatment.

Abstract
Carcinosarcoma is an uncommon mixed tumor of the lung. We present the case of a 65 year-old-male with cough and a right lower lobe radio-opacity who underwent resection, showing a large endobronchial tumor with an epithelial component of non-small cell carcinoma and malignant mesenchymal elements. The radiologic and histopathologic features are reviewed with reference to relevant literature.
