ABSTRACT
A case of an 82-year-old female with primary laryngeal cryptococcosis who had undergone long-term corticosteroid therapy for chronic obstructive pulmonary disease and rheumatoid arthritis is reported. She complained hoarseness with swallowing pain and irritability of the larynx for over a month. Endoscopic examination revealed a white, exudative irregular region on right arytenoid that mimicked a laryngeal carcinoma. Histological examination showed pseudoepitheliomatous hyperplasia and severe submucosal inflammation with ovoid budding yeasts by Grocott's stain. A serological study indicated a high titer of cryptococcal antigen. After treating with oral fluconazole for 3 months, her primary lesion of larynx turned to be clear. We implicate a long-term use of steroids as the significant risk factor in developing cryptococcosis of the larynx.
