Fibro-osseous lesions of the jaws: An insight

Isha Chauhan, Swati Roy, Vipul Garg, Kavita Manchanda


Fibro-osseous lesions of the jaws comprise a diverse group of conditions, which are characterized by replacement of normal bone by fibroblasts, collagen fibers, and mineralized tissue. The diagnosis based on microscopy alone is often impossible due to overlapping of histopathologic features. Adequate clinical and para clinical observations, such as patient’s age, sex, location of the lesion, duration of symptoms, imaging characteristics, and histologic findings are necessary to arrive at an accurate diagnosis.Certain cases present features that may be atypical and do not favor a definite diagnosis. Sound knowledge of various fi bro-osseous lesions of craniofacial structures is critical for proper interpretation and diagnosis of these lesions. Despite striking similarity in the clinical, radiographic and to some extent the histologic patterns, the biologic behavior varies; so each lesion may require a diff erent treatment approach. In this review, the most important and frequent features of the fi bro-osseous lesions of jaws along with diff erent classifications are discussed.
