Primary non-Hodgkin's lymphoma of bone (PLB) is rare, and generally presents as a single extensive and destructive bone lesion. Histopathologically, most cases present as diffuse large B-cell lymphoma, and T-cell lymphoma is rare. By contrast, multiple myeloma is a disease defined as the neoplastic proliferation of a single clone of plasma cells producing a monoclonal immunoglobulin. We report a case of multiple myeloma that developed during treatment of PLB in a type of T-cell. A 48-yr-old man was diagnosed as T-cell PLB, stage IE, 18 months ago. The patient received the chemoradiotherapy and salvage chemotherapy for PLB. However, the lymphoma progressed with generalized bone pain, and laboratory findings showed bicytopenia and acute renal failure. On bone marrow biopsy, the patient was diagnosed as having multiple myeloma newly developed with primary T-cell lymphoma of bone. In spite of chemotherapy, the patient died of renal failure.

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.
