Extranodal NK/T-cell lymphoma, nasal type (ENKL) is a rare lymphoid neoplasm that in the past has been grouped with a variety of granulomatous diseases. ENKL occurs in all age groups. However, it seems to occur more often in people in their 50s and affects more men than women. It is strongly linked to the Epstein-Barr virus (EBV), especially in people of Asian countries. Because this type of lymphoma occurs in organs or tissues other than lymph nodes, it is called ENKL. This is a case report of a 25-year-old female patient who presented with a nonhealing ulcer at the right nasal ala involving the upper lip and cheek for the last 2 months, which had been treated with antitubercular treatment without success. After biopsy and immunohistochemical (IHC) analysis, the patient had been diagnosed a case of extranodal T-cell lymphoma.
