Fibrous dysplasia is a category of fibro-osseous lesions which demonstrates replacement of normal bone by a fibrous connective tissue matrix, within which varying amounts of metaplastic osteoid, immature and mature bone & in some instances, cementum like tissue are deposited. Among the two types of fibrous dysplasia, like the monostotic forms and the polyostotic form; the monostotic type of fibrous dysplasia is more commonly seen. We present a case of an isolated monostotic fibrous dysplasia of the temporal bone with clinical, radiographic, microscopic features along with the management of the same.
