Gorham's Disease

Gorham’s disease (pronounced GOR-amz) is a very rare skeletal condition of uncertain etiology, characterized by the uncontrolled proliferation of distended, thin-walled vascular or lymphatic channels within bone, which leads to resorption and replacement of bone with angiomas and/or fibrosis. Because of the loss of the affected bone, the condition has been referred to as disappearing bone disease, vanishing bone disease, and massive osteolysis. In medical terminology osteolysis means: bone (osteo) breaking down or destruction (lysis).
