At autopsy, severe osteosclerosis and localized plasmacytomas were found. Osteosclerosis is an unusual accompaniment of the plasma cell dyscrasias, and the finding of it tends to discredit the diagnosis of myeloma. Recent studies, however, support the contention that osteosclerosis may occur in myeloma. We postulate that the osteosclerosis may well be a reflection of a myeloproliferative process involving various marrow elements at different times.

The peripheral smear revealed the presence of teardrop forms, ovalocytes, and nucleated red blood
