Crystalglobulinemia syndrome. A manifestation of multiple myeloma.

ABSTRACT

BACKGROUND: Crystalglobulinemia syndrome (CS) is a rare vasculopathy that may arise as a complication of multiple myeloma (MM). METHODS AND RESULTS: 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. CONCLUSION: 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.
