title: Friedrich's disease: a case report.
abstract: An eight-year-old girl was presented with painful swelling of the sternoclavicular joint. Radiological and scintigraphic examinations lead to a diagnosis of Friedrich's disease, aseptic necrosis of the sternal end of the clavicle. It is a rare condition which is to be differentiated from osteomyelitis, arthritis, or tumor. Because it is a self-resolving, benign condition, awareness of this disease will save the patient from unnecessary surgery.
