[Typical, atypical and malignant bronchial carcinoid].

A series of 54 bronchial carcinoids operated in the course of 12 yr is presented. There were three histological types: typical, atypical and malignant. A parallel was also apparent between histological appearance and clinical pattern. Correct prognosis, however, demands the examination of other parameters, such the tendency of the neoplasia to infiltrate, and the presence of metastatic lymph nodes.
