SURGICAL MANAGEMENT OF A RARE CASE OF GORHAM’S DISEASE OF MANDIBLE: A CASE REPORT WITH REVIEW OF LITERATURE. Narayan dutt pandey, PGT Department of Oral & Maxillofacial Surgery, G.N.I.D.S.R ,Kolkata ABSTRACT Gorham’s disease is a rare disorder characterized by proliferation of vascular channels that results in destruction and resorption of osseous matrix. Since the initial description of the disease by Gorham and colleagues (1954) and by Gorham and Stout (1955), the precise etiology of Gorham’s disease remains poorly understood and largely unknown. There is no evidence of a malignant, neuropathic, or infectious component involved in the causation of this disorder. The mechanism of bone resorption is unclear. The first facial case of GD was described by Römer in 1928. Since this description nearly 40 or more maxillofacial cases have been reported. Jaw is the main location in the reported maxillofacial cases. In the present case report a 55 yr old female patient has been successfully managed surgically with encouraging early postoperative results.
