Abstract:
A 59-year-old man was referred to our hospital for the evaluation of pain on exertion of the right arm. X-ray examination showed a humeral tumor, and a tumorectomy was subsequently performed. The histological analysis showed necrotic tissue with no malignant cells. Serum protein electrophoresis yielded a small amount of M proteins without monoclonality of immunoglobulins. The bone survey in the whole body showed lucency of the right humerus, vertebra, ribs, left femur, skull, and right scapla. During outpatient clinic observation, a computed tomography scan of the pelvis showed a painless large tumor in the gluteus, appearing as an amyloidoma. Soft tissue amyloidoma occur very rarely, and so we here report a case of a soft tissue amyloidoma in the gluteus with review of the literatures.
