ABSTRACT
Fibrous dysplasia remains one of the most frequently encountered osseous craniofacial tumors
(1). A benign fibro-osseous disease, its etiology continues to be poorly defined (2,3). Fibrous
dysplasia was first described in publication by Von Recklinghausen in 1891 (4), and it was later
fully characterized and named as such by Lichtenstein in 1938 (5). The pathologic process
results in the gradual infiltration of normal bone with fibrous tissue intermingled with
immature woven bone arranged in an erratic trabeculated pattern (6).
