Amyloidoma primarily involving bone and lymph node is described in a 60-year-old male patient. The patient had pathologic fractures of both hips through a deposit of amyloid in the neck of the femur. The prolonged insidious course of the disease was uncomplicated by hypercalcemia, hematologic abnormalities, or renal failure so characteristic of untreated myeloma. The bone marrow contained less than 10 percent plasma cells in different stages of maturity. Radionuclide bone scanning demonstrated other osseous amyloid lesions that were not detected by routine radiologic examination. This is the first reported case of pathologic fractures of both hips secondary to amyloidoma.
