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.
外生性支气管表皮样癌是一种罕见的临床实体。作者描述并系统分析了35年间收集的34例病例。男性患者居多；就诊时的平均年龄为58岁。肿瘤几乎总是处于T1N0期，其预后并不优于其他I期支气管源性癌。研究结果表明，它们是支气管源性癌的一种特殊亚型，而非早期发现的肿瘤。
