A case of fungal infection of the larynx requiring differential diagnosis from laryngeal carcinoma is reported. A 75-year-old male was referred to our clinic with a complaint of hoarseness, and a mass lesion was detected on the left vocal cord. Biopsy under laryngeal fiberscopy was performed on suspicion of laryngeal carcinoma. Resection and vaporization of the lesion was carried out using a KTP laser, because the intraoperative histopathological diagnosis was dysplasia. The final histopathological diagnosis was revised to dysplasia with an infection of Aspergillus. Additional therapy for the fungal infection was not performed, but no reccurence was seen for 3 years after surgery. The post-vaporization lesion on the vocal cord was covered with intact mucosa. KTP laser was found to be effective in this case.
Key words : fungal infection, larynx, KTP laser, dysplasia
