Vascular amyloid in a patient with multiple myeloma.
A patient developed nodules on the scalp in the distribution of blood vessels and was found to have multiple myeloma. Biopsy of a nodule and of muscle demonstrated amyloid in the vasculature. Clinical manifestations of vascular amyloid are discussed. Cutaneous nodules along the course of vessels and symptoms of peripheral vascular disease may be presenting signs of systemic amyloidosis.
