Crystalglobulinemia syndrome. A manifestation of multiple myeloma.

Abstract

Crystalglobulinemia syndrome (CS) is a rare vasculopathy that may arise as a complication of multiple myeloma (MM). A patient with multiple myeloma in whom crystalglobulinemia syndrome was the initial manifestation with polyarthralgias, cutaneous ulceration, and lower limb ischemia requiring bilateral amputations is reported. The rare syndrome of crystalglobulinemia may be associated with multiple myeloma, so it is important that clinicians be aware of this syndrome and its clinical and morphologic features.
