Gorham disease in the maxilla.

Gorham disease is a rare condition that is characterized by the proliferation of thin-walled vascular channels associated with regional osteolysis. The exact etiology of Gorham disease is unknown. The diagnosis of Gorham disease is based on clinical, radiological, and histological features after excluding osteolysis, which is secondary to other pathologic processes. Those pathologic processes include congenital, metabolic, neoplastic, and immunologic etiologies and infections. The appearance of the disease in the craniofacial region often involves the mandible. In the reported literature (English language only), there is 1 reported case of the disease located in the maxilla alone. In this study, we present another case of Gorham disease that presents in the maxilla of a 37-year-old man.
