Carcinoid tumor of the larynx.
A patient had a primary carcinoid tumor of the larynx. This is the second case reported in the American or British literature and the only one confirmed by a positive argyrophilic reaction and by the demonstration of neurosecretory-type granules by electron microscopy. The patient's clinical course was similar to that seen in most cases of tracheal and bronchial carcinoids.
