Exophytic endobronchial epidermoid carcinoma.

Exophytic endobronchial epidermoïd carcinoma is a rare clinical entity. The authors describe and systematically analyzed 34 cases, collected during 35 years. There was a preponderance of male patients; the mean age at presentation was 58 years. The tumors were nearly always at the T1N0 stage, and their prognosis was not better than that for other Stage I bronchogenic carcinomas. The findings suggest that they are a special subvariety of bronchogenic carcinoma, rather than tumor detected at an early stage.
