Type IV osteolysis or Gorham-Stout syndrome is a rare condition characterized by recurrent vascular tumors that disrupt normal anatomical architecture. Gorham-Stout syndrome is most commonly associated with the skeletal system with resulting replacement of bone with scar tissue following tumor regression. The loss of entire bones has given Gorham-Stout syndrome the moniker vanishing bone diseas...

RATIONALE Gorham-Stout disease (GSD) is characterized by aggressive bone resorption, proliferation of vascular or lymphatic vessels, and soft-tissue swelling. Bones that initially appear normal start to resorb, partially or completely. However, the etiology of GSD is unknown. PATIENT CONCERNS A 29-year-old man with a chief complaint of toothache and mobility in the lower right mandible for th...

Gorham-Stout syndrome is a rare disorder that leads to extensive lymphangiomatosis in bones with resorption of adjacent bone matrix. As a result, the disease is also known as massive osteolysis or “vanishing bone disease.” Although the disease primarily occurs in bone, it may also involve adjacent soft tissues. We report a case of Gorham-Stout syndrome presented with chylotamponade as a result ...

Gorham-Stout disease is a rare disease characterized by anarchic lymphovascular proliferation causing resorption of bone sometimes leading to disastrous complications. Bone tissue is progressively replaced by angiomatic and lymphangiomatic tissue and finally by fibrous tissue. This disease is known to be ubiquitous and of complex etiology. We present a case of Gorham-Stout disease of the proxim...

Gorham-Stout syndrome (GSS), also known as Gorham-Stout disease, massive osteolysis, disappearing bone disease or phantom bone, is a rare disorder of the musculo-skeletal system. It most commonly involves the skull, shoulder and pelvic girdle. Histological examination reveals a progressive osteolysis always associated with an angiomatosis of blood vessels and sometimes of lymphatics, which seem...
