A nasal-type extranodal natural killer/T-cell lymphoma is considered an aggressive form of non-Hodgkin's lymphoma, with approximately half of all patients relapsing during the follow-up period, and most relapses occurring within the first 2 years of remission. Here we report an unusual case of a 42-year-old man who experienced recurrence in single pleura after 8 years of remission.
