[Spontaneous idiopathic osteolysis (Gorham syndrome). A case report]

The spontaneous idiopathic osteolysis is know as a slow progressive absorbtion process of the bone with unknown causes. It is supposed that in the "Gorham-Syndrom" a hämangiomatosis of the bone exists. In some cases of spontaneous osteolysis there wasn't any vascular proliferation noted. One case with spontaneous osteolysis will be discussed. The histological picture of this patient is described as a chronic uspecific osteoarthritis. Another case could be documented radiologically at the left distal ulna. The attribution of these cases to the "Gorham-Syndrom" is discussed.
