Mycosis fungoides of the larynx. Report of two cases and review of the literature.

Involvement of the larynx by mycosis fungoides is extremely rare with only three reported clinical cases in the English-language literature. We present two patients with laryngeal mycosis fungoides, one of whom presented with vocal cord paresis (progressing to paralysis) as the initial clinical manifestation of laryngeal involvement. Our clinical findings and the observations from the three previous case reports suggest that laryngeal mycosis fungoides has a predilection for the arytenoids, aryepiglottic folds, and the laryngeal surface of the epiglottis. Laryngeal involvement, like other forms of visceral dissemination, appears to manifest clinically in the terminal stages of the disease. The natural history, clinical features, histopathology, and treatment of mycosis fungoides are reviewed and the etiopathology of the vocal cord paralysis is described.
