Solitary bronchial mucosal neuroma.

A 68-year-old man who had had cough and sputum for ten months was referred to our hospital because sputum cytologic findings were suggestive of lung cancer. Fiberoptic bronchoscopy and biopsy revealed mucosal neuroma of the bronchi. There were no signs suggesting pheochromocytoma or medullary thyroid carcinoma. To our knowledge, this is the first case of solitary mucosal neuroma of the bronchi to be reported.
