• An unusual case of cryptococcosis of the larynx initially developed as an acute upper airway obstruction that necessitated tracheostomy. Concomitant findings were tracheobronchial ulcerations and edema with severe mainstem bronchial constriction on the left side.

Budding "yeast-like organisms" that were consistent with Cryptococcus neoformans appeared in tissue specimens. Epithelial changes that were consistent with pseudoepitheliomatous hyperplasia occurred in areas in the immediate vicinity of the organisms.

Sputum and bronchial washing cultures grew nonmycelial, mucinous, encapsulated forms that were positive to staining with mucicarmine and Alcian blue.

Treatment with amphotericin B resulted in resolution of the laryngeal obstruction, permitting decannulation. Follow-up direct laryngoscopy and biopsy three months after completion of therapy revealed only mild edema of the false vocal folds. No organisms were found in the tissue, and the pseudoepitheliomatous hyperplastic mucosal changes had resolved.
