A Case of Mycosis Fungoides in the Larynx and Pharynx

Abstract

Mycosis fungoides (MF) is the most common type of cutaneous malignant T-cell lymphoma, but reports of MF in the head and neck region are rare. We report herein on a case we experienced in which MF invaded the larynx and pharynx. An 80-year-old man, who was seeing his dermatologist, visited a local hospital complaining of dysphagia, where a lesion in the epiglottis on the right aryepiglottic folds was discovered, and the patient was referred to our hospital for further examination. A biopsy of the area of interest confirmed the presence of MF and the patient was immediately sent for radiation therapy. Three months thereafter, an elevated MF lesion appeared on the posterior part of the tongue, so the patient underwent additional radiation therapy of the entire pharynx. Since no recurrence was seen 12 months after the end of the treatment regimen in our department, radiotherapy for potentially malignant lesions of the larynx and pharynx is suggested as a valid approach.
