Fibrous dysplasia of the pediatric anterior maxilla: A case report and review of literature

Abstract

Fibrous dysplasia (FD) is a benign fibro-osseous lesion in which the fibrous connective tissue containing abnormal bone replaces normal bone. FD is linked to GNAS1 guanine nucleotide-binding protein, alpha-stimulating activity peptide 1, and the gene mutation resulting in the abnormal proliferation and differentiation into pre-osteoblast. In this case report, we present a case of 9 years old boy with monostotic FD affecting the left maxilla causing bony expansion and asymmetry of the right side of face.
