Primary bronchial tumors in childhood. A clinicopathologic study of six cases.

A primary bronchial tumor was diagnosed in six children younger than age 12 years. These cases include four bronchial carcinoids, a low-grade mucoepidermoid carcinoma, and a granular cell tumor ("myoblastoma"). Lobar or segmental resection was performed in each case and remains the treatment of choice. The most common bronchial tumors in childhood are carcinoids with 17 other evaluable cases in the English Literature. This series includes the youngest child to be reported with bilateral choroidal metastases leading to blindness; in addition, there were clinical manifestations of gigantism and acromegaly possibly related to ectopic hormone production. Low-grade mucoepidermoid carcinomas rank second in frequency to carcinoids and have an excellent prognosis. Judging from the childhood bronchial tumors reported to date, proved examples of bronchogenic carcinoma are vanishingly rare.
