Gorham-Stout disease (GSD) is a rare disease of massive osteolysis associated with proliferation and dilation of lymphatic vessels. GSD may affect any bone in the body and can be monostotic or polyostotic. Symptoms at presentation are dependent upon the location(s) of the disease; the most common symptom is localized pain. The disease may be discovered after a pathological fracture.
