We report a case of malignant epiglottic natural killer (NK)/T cell lymphoma. A 33-year-old man seen 1-month period for throat pain was found in endoscopic larynx examination to have inflammation with plaques and redness epiglottic. The 4 month period, right epiglottic inflammation showed progressive necrosis. The diagnosis of malignant lymphoma was confirmed by 3 biopsies. Laryngomicrosurgery specimens histologicalily showed moderate leukocytic infiltration mainly of atypical lymphocytes. Neoplastic cells were UHCL1+, CD3+, L26-, CD79a, and EBER-ISHW. Despite 4 units of DeVIC chemotherapy and regional irradiation, the man died of metastatis 1 year and 9 months after initial treatment.
