Extranodal NK/T-cell lymphoma, nasal type (ENKTL-NT) is a rare form of non-Hodgkin’s malignant lymphoma, accounting for 1.4% of all lymphomas [1]. It is highly invasive and has a predilection for the nasal cavities, nasopharynx, and paranasal sinuses. It often affects middle-aged men and is strongly associated with Epstein- Barr virus (EBV). The incidence of ENKTL varies greatly from region to region, being highest in East Asia and Latin America where EBV infection in young children is widespread. We report two cases of extranodal NK/T-cell lymphoma of the nasal type diagnosed at a localized stage.
