FIBROUS DYSPLASIA OF MAXILLARY BONE- A CASE REPORT
Sonam Bhalla, Poonam Goel, Sneha Sethi

Fibrous dysplasia is a rare benign intramedullary fibroosseous lesion. It is a genetic noninherited condition caused by mutation in the GNAS1 gene, characterized by abnormal proliferation of fibrous tissue interspersed with normal or immature bone. It occurs in equal proportions in males and females, most often during the first two decades of life. Long bones, skull bones and ribs are the most commonly affected bones. The radiological picture is somewhat variable, including a ground-glass appearance, expansion of the bone and sclerosis surrounding  the lesion. Histologically, fibrous dysplasia shows irregularly-shaped trabeculae of immature, woven bone in a background of variably cellular, loosely arranged fibrous stroma. Computed Tomography is the best technique for demonstrating the radiographic characteristics. Here we report a case of fibrous dysplasia in 35 year old male patient.
Key Words: Fibrous dysplasia, maxilla, craniofacial, computed tomography
