title: Bone lesions in primary amyloidosis.
abstract: Amyloidosis primarily involving bone is described in a 59-year-old male pateint. Well circumscribed lytic lesions of the skeleton raised the possibility of myelomatosis. The prolonged insidious course of the disease was uncomplicated by hypercalcemia, pathological fracture, or hematologic abnormalities. The clinical course, together with histological findings and strongly positive bone scan, were the distinguishing features. The osseous manifestations without plasma cell tumor appears to be a rare occurrence in amyloidosis.
