Angioleiomyoma of the larynx. Report of a case and review of the literature.

A rare case of angioleiomyoma in a 76-year-old man is presented. The main symptoms were hoarseness and dyspnea. The tumor originated in the subglottic surface of the right vocal cord and there was only 3 mm of the laryngeal inlet free of the tumor. Histopathologically it was well circumscribed and composed of proliferating smooth muscle fibers and dilated blood vessels. The tumor was partially removed endoscopically, and subsequent cryotherapy was instituted. After two courses of cryotherapy the tumor had completely disappeared. Laryngeal function was restored to normal, and no signs of recurrence were observed after follow-up of 8 months.
