A case of IgD "nonsecretory" multiple myeloma in a 46-yr-old woman is reported. Despite the presence of disseminated osteolytic lesions, both serum protein electrophoresis and serum and urine immunoelectrophoresis were normal. In addition, bone scintigraphic study was normal. Bone marrow biopsy and aspirate obtained from the left femur lytic lesion showed only myelomatous proplasmocytes; when examined by immunofluorescence with monospecifc antisera, the cytoplasm showed only the presence of delta and kappa chains, suggesting that the neoplastic plasma cells might belong to a single clone. Lymphocyte studies indicated the presence of a normal amount of both B and T cells.
