Extranodal natural killer (NK)/T‐cell lymphoma, nasal type, is a rare lymphoma that occurs predominantly in Asian adults. In this report, we describe the clinical and pathologic features of an unusual aggressive lymphoid neoplasm in a child and review the literature on NK/T‐cell lymphoma in children. The patient was a 4‐year‐old Native American male with facial swelling, lymphadenopathy, and fevers. Biopsy demonstrated neoplastic lymphoid cells that expressed CD3, CD8, TIA‐1, and EBV‐encoded RNA without CD56. The patient failed multiagent chemotherapy and died of therapy‐related complications. This case represents an extranodal NK/T‐cell lymphoma, nasal type, with an unusual lack of CD56. Pediatr Blood Cancer 2010;55:186–189. © 2010 Wiley‐Liss, Inc.
