Plasma cell sclerosis of bone: a spectrum of disease.

We describe the clinical, radiographic, and pathologic manifestations of a group of disorders characterized by osteosclerosis in association with plasmacytic infiltration of bone marrow. These conditions include multiple myeloma, plasma cell granuloma, sternocostoclavicular hyperostosis, the POEMS syndrome (plasma cell dyscrasia with polyneuropathy, organomegaly, endocrinopathy, M-protein, and skin changes), and chronic symmetric plasma cell osteomyelitis of childhood. Although clinically unrelated in many respects, features shared by these diseases support the existence of a specific factor linking the plasma cell to local osteogenesis.
