Extranodal NK/T cell lymphoma is a relatively uncommon type of non-Hodgkin's lymphoma, which is prevalently distributed in Asia and South America, and is highly associated with Epstein-Barr virus (EBV) infection. Due to its highly aggressive course and poor response to treatment because of its multi-drug resistance, for the timebeing there is not yet a definite treatment strategy. The clinical manifestation, pathological diagnosis and the progress of treatment methods of ENTNKCL are reviewed below.
