A 51-year-old @entity1 had suffered from massive @entity1143 due to invasion of malignant cells. The analysis of bone marrow aspiration showed the proliferation of myeloperoxidase-positive blasts. The surface marker analysis of the blasts revealed the positivities for @entity4587 and @entity1075 as well as @entity10793 , @entity1116 and @entity2280 , while the karyotypes of 20 cells were normal. Therefore, @entity4587 positive @entity3052 was diagnosed. The @entity1 was treated with araC and @entity5699 as a remission induction therapy. Peripheral blood stem cells were harvested by leukapheresis after first and second consolidation therapies. Then, 3 x 10(4) cells/kg of CFU-GM were infused. Complete remission has been maintained for 8 months after autologous blood stem cell transplantation. Pleural involvement as an initial manifestation is rare in @entity3052 . Extramedullary growth of @entity3052 cells may be related to their immaturity, indicated by the expression of the cell surface antigens.
