We report the case of a 69-year-old man with NK/T cell lymphoma who developed a recurrent lesion in the larynx after radiotherapy. He presented with the chief complaint of hoarseness, and endoscopic examination revealed inflammation with plaques in the right subglottic area. The diagnosis of extranodal NK/T cell lymphoma was confirmed by biopsy of the laryngeal lesion, and the tumor was treated by radiotherapy. At the 1-year follow-up, endoscopic examination of the larynx revealed that it was tumor-free, and FDG-PET showed no evidence of recurrence. Laryngeal NK/T cell lymphoma is very rare, and a definitive histopathological diagnosis is often difficult due to the location of the tumor and the perilesional inflammation and necrosis.
