Amyloidosis complicating multiple myeloma is an uncommon but well-recognized phenomenon. Multiple bone amyloidomas are rare as the initial presenting feature of myeloma. Solitary bone amyloidomas share common features with those of patients who have solitary plasmacytomas and progression to disseminated myeloma is common. We report a case of an elderly man who presented with extensive amyloid deposition in multiple plasmacytoma sites as well as evidence of amyloid in a fat pad aspirate but with none of the usual organ damage associated with systemic amyloidosis. This presentation is similar to a subset of patients said to have macrofocal myeloma. These patients are typically aged < 40 years, have no bone marrow involvement, and have a good prognosis. This report may represent the first description of macrofocal myeloma associated with amyloid deposition in an older individual.

D009101 Multiple Myeloma A malignancy of mature PLASMA CELLS engaging in monoclonal immunoglobulin production. It is characterized by hyperglobulinemia, excess Bence-Jones proteins (free monoclonal IMMUNOGLOBULIN LIGHT CHAINS) in the urine, skeletal destruction, bone pain, and fractures. Other features include ANEMIA; HYPERCALCEMIA; and RENAL INSUFFICIENCY.

D000686 Amyloidosis A group of sporadic, familial and/or inherited, degenerative, and infectious disease processes, linked by the common theme of abnormal protein folding and deposition of AMYLOID. As the amyloid deposits enlarge they displace normal tissue structures, causing disruption of function. Various signs and symptoms depend on the location and size of the deposits. Amyloidoses
D018450 Disease Progression The worsening and general progression of a disease over time. This concept is most often used for chronic and incurable diseases where the stage of the disease is an important determinant of therapy and prognosis.
