Extranodal non-Hodgkin lymphoma is uncommonly occurred in larynx, accounting for less than 1% of all laryngeal neoplasm. In general, the laryngeal lymphoma is appeared submucosal mass without mucosal ulceration and is most commonly found in supraglottic area. The primary laryngeal lymphoma constitute a diagnostic challenge because they are characterized by absence of clinical and gross differential criteria, compared with SCC (squamous cell carcinoma). We encountered a 74-year-old man with hoarseness and lump sensation in the throat. On direct laryngoscope, multiple ulcerative and exudative mass in glottis and supraglottic areas were observed. The patient was finally diagnosed as lymphoma through laryngeal microsurgery. He received radiation therapy and so far, there is no evidence of recurrence. Surgeons should take into account a primary laryngeal lymphoma with SCC, even though the mass has superficial mucosal change.
