[Intermittent claudication disclosing amyloidosis in a chronically hemodialysed patient with light-chain myeloma]

The occurrence of amyloid deposits in skeletal muscle and its vessels has been noted from a long date in amyloidosis. However, their clinical manifestations have been seldom noticed. The authors report the case of a patient with light-chain myeloma in which an arterial intermittent claudication led to the discovery of muscle vascular amyloid deposits. Muscle signs and symptoms due to amyloidosis and their mechanisms are reviewed.
