[Waldenström's macroglobulinemia and peripheral amyloid neuropathy (author's transl)]

A 77-year-old man was diagnosed as having Waldenström's macroglobulinemia sex years after developing a sensory-motor neuropathy of the four limbs. The amyloid nature of the neuropathy was confirmed after biopsy of a peripheral nerve. The pathogenesis of the amyloidosis occurring during the course of dysglobulinemias is discussed, and those dysglobulinemias associated with non-amyloid neuropathies briefly described.
