Abstract
A few cases of multiple myeloma associated with myelofibrosis has been reported. In Japan, such cases have been less reported. We report a case of IgD-myeloma with remarkable marrow fibrosis. A 44-year-old female was admitted to our hospital because of back pain. On admission her peripheral blood revealed anemia and leukopenia. Serum immunoelectrophoresis revealed M-protein of IgD and serum IgD level remarkably increased to 5420 mg/dl. Bone marrow aspiration resulted in dry tap every three times and its biopsy at iliac bone showed remarkable infiltration of myeloma cell and remarkable increase of reticulin fiber with marked decrease of normal hematopoietic cells. Her liver and spleen were not palpable and tear drop cells of erythrocytes were not shown in peripheral blood. We could not find view of myelofibrosis with chronic myeloproliferative disorders. Multiple myeloma associated with myelofibrosis is a interesting syndrome as clinical signs and course. So further investigation must be needed.
