Abstract
Introduction: Fibro-osseous lesions constitute a rare benign type of pathology with a non-odontogenic lineage that affect the craniofacial area. According to Waldrom’s classification, these lesions are divided into: fibrous dysplasia (FD), cemento-ossifying fibroma (COF) and desmoplastic fibroma (DF). Material and Methods: A retrospective study was performed on patients diagnosed with fibro-osseous lesions of the craniofacial area at the Hospital Universitario La Fe, Valencia, during 1987-2009. A total of 19 cases were collected: 15 cases compatible with an FD diagnosis, 3 cases with a COF diagnosis and 1 case with a DF diagnosis. Results: In the differential diagnosis, entities having similar clinical manifestations in the maxillofacial area with possible involvement of teeth or manifestations present as an asymptomatic radiolucent image should be ruled out. We hereby present the management and development of patients treated in our hospital for fibro-osseous lesions. Conclusions: Fibro-osseous lesions share many clinical and radiological characteristics in common, with histological features confirming the nature of the lesion. Management of patients should be individualized and case-specific, assessing the clinical evolution of each case and taking into account the benign nature and growth behavior of this type of tumors. Key words:Fibro-osseous, fibrous dysplasia, cemento-ossifying fibroma, desmoplastic fibroma.
Highlights
Fibro-osseous lesions constitute a rare benign type of pathology with a non-odontogenic lineage that affect the craniofacial area
According to the classification proposed by Waldrom [3] in 1993, this type of pathology is divided into fibrous dysplasia (FD), cemento-ossifying fibroma (COF) and desmoplastic fibroma (DF)
Fifteen cases had a diagnosis compatible with FD, 3 were compatible with a COF diagnosis and 1 case was compatible with a DF diagnosis
Summary
Fibro-osseous lesions constitute a rare benign type of pathology with a non-odontogenic lineage that affect the craniofacial area. Fibro-osseous lesions constitute a rare type of pathology classified as benign tumors of non-odontogenic lineage that affect the craniofacial area. These lesions were first described by Lichtenstein [1,2] in 1936, and have undergone several changes in terms of classification and identification over the years. According to the classification proposed by Waldrom [3] in 1993, this type of pathology is divided into fibrous dysplasia (FD), cemento-ossifying fibroma (COF) and desmoplastic fibroma (DF) These entities differ from each other due to different clinical, radiological, and histological characteristics that help make a diagnosis (Table 1). The course of treatment should be planned and individualized in each case based on the manifestations
