Malignant endobronchial lesions of adolescence.

Rare primary endobronchial malignancies were diagnosed in four adolescents: atypical bronchial carcinoid, mucoepidermoid carcinoma, bronchogenic (squamous cell) carcinoma, and non-Hodgkin's lymphoma. Metastatic disease was evident in each case. Three of the four patients died within one year of diagnosis. This paper describes each of these entities, illustrates their plain film and CT abnormalities (bronchial "cut-off", hilar mass, local congestive edema, lobar collapse, hyperinflation), and discusses the utility of CT in their diagnosis.
