2/27. Aggressive cemento-ossifying fibroma of the jaws.The cemento-ossifying fibroma is probably the most frequent fibro-osseous lesion seen by oral pathologists. Occasionally, reports of lesions behaving in an aggressive fashion appear in the literature. At the present time, the relationship if these "aggressive" lesions to the "usual" fibromas is unclear. Two cases of "aggressive" cemento-ossifying fibroma are reported. Certainly, clinical, radiological, and histological characteristics of aggressive and usual fibromas do coincide. There are, however, diverging features warranting separation of different forms. These mild differences may be detected during preoperative assessment of the lesion, allowing a diagnosis of aggressive form to be made.- - - - - - - - - - ranking = 0.63717619782287keywords = jaw (Clic here for more details about this article) |
3/27. Juvenile ossifying fibroma of the mandible. An 8 year radiological follow-up.An 8-year follow-up of a juvenile ossifying fibroma in the left mandible of a 4-year-old boy is presented. The case demonstrated initial lack of radiological evidence of demarcation and subsequent eccentric enlargement, selective tooth displacement and a multilocular appearance in areas of active growth. An aneurysmal bone cyst and a decrease in the bone content was present in the excision specimen.- - - - - - - - - - ranking = 5keywords = mandible (Clic here for more details about this article) |
4/27. Ossifying fibroma arising in the right ethmoid sinus and nasal cavity.Ossifying fibroma, a rare tumor entity, is a well-demarcated benign fibro-osseous tumor composed of bone, fibrous tissue and cementum. It is commonly found in the mandible, but also found in the maxilla and paranasal sinuses. Simple curettage is enough when the fibrous lesions are located in the mandible but a complete en bloc excision is required when these lesions are located in the maxilla and paransal sinuses to relieve symptoms and prevent recurrence. With the advent of sinonasal endoscopy in the mid 1980s, and subsequent advances in surgical techniques, endoscopic management of the fibrous-osseous lesions has become possible. In the current case study, we report a successful endoscopic removal of a huge ossifying fibroma located in the right ethmoid sinus and nasal cavity.- - - - - - - - - - ranking = 2keywords = mandible (Clic here for more details about this article) |
5/27. Developing cementoblastoma: case report and update of differential diagnosis.The benign cementoblastoma is a rare odontogenic tumor that tends to occur in the jaws of young people. It is most commonly characterized as a circumscribed radiopaque mass attached to the tooth roots and rimmed by a thin radiolucent zone. Early lesions, however, are radiolucent and can be confused with periapical conditions resulting from nonvital teeth. The tumor is seldom recognized until it produces pain or expansion of the jaw. If the diagnosis is established early, the tooth can be saved by endodontic treatment followed by apical root resection and surgical enucleation of the tumor. This case report documents the origin, development, and unlimited growth potential of a cementoblastoma. Radiographs taken at yearly intervals reveal an initial widening of the periodontal ligament space that grew into a 3-cm mixed radiolucent and radiopaque tumor over a 4-year period. The differential diagnosis and some criteria to help distinguish the cementoblastoma from similar-appearing lesions are reviewed.- - - - - - - - - - ranking = 0.31858809891144keywords = jaw (Clic here for more details about this article) |
6/27. Gnathodiaphyseal dysplasia: a syndrome of fibro-osseous lesions of jawbones, bone fragility, and long bone bowing.We report an unusual generalized skeletal syndrome characterized by fibro-osseous lesions of the jawbones with a prominent psammomatoid body component, bone fragility, and bowing/sclerosis of tubular bones. The case fits with the emerging profile of a distinct syndrome with similarities to previously reported cases, some with an autosomal dominant inheritance and others sporadic. We suggest that the syndrome be named gnathodiaphyseal dysplasia. The patient had been diagnosed previously with polyostotic fibrous dysplasia (PFD) elsewhere, but further clinical evaluation, histopathological study, and mutation analysis excluded this diagnosis. In addition to providing a novel observation of an as yet poorly characterized syndrome, the case illustrates the need for stringent diagnostic criteria for FD. The jaw lesions showed fibro-osseous features with the histopathological characteristics of cemento-ossifying fibroma, psammomatoid variant. This case emphasizes that the boundaries between genuine GNAS1 mutation-positive FD and other fibro-osseous lesions occurring in the jawbones should be kept sharply defined, contrary to a prevailing tendency in the literature. A detailed pathological study revealed previously unreported features of cemento-ossifying fibroma, including the participation of myofibroblasts and the occurrence of psammomatoid bodies and aberrant mineralization, within the walls of blood vessels. transplantation of stromal cells grown from the lesion into immunocompromised mice resulted in a close mimicry of the native lesion, including the sporadic formation of psammomatoid bodies, suggesting an intrinsic abnormality of bone-forming cells.- - - - - - - - - - ranking = 1.11505834619keywords = jaw (Clic here for more details about this article) |
7/27. Prosthodontic implant rehabilitation after the treatment of a pathologic lesion in the mandible: a case report.A case is reported of an extensive ossifying fibroma involving the mandible and its successful rehabilitation by using an osseointegrated implant. The lesion was enucleated under general anesthesia along with involved teeth Nos. 35, 36, 37, and 38. Regular radiographic follow-up showed complete bone healing within the period of two years. A free-end saddle removable partial denture was avoided by the appropriate use of root-form implants.- - - - - - - - - - ranking = 5keywords = mandible (Clic here for more details about this article) |
8/27. Unusual jaw lesions in the paediatric and adolescent patient: a management challenge.While major maxillofacial pathology in the young patient is relatively uncommon, non-malignant conditions may pose a significant treatment dilemma due to their aggressive or unpredictable behaviour. Several such diseases managed by the Oral and Maxillofacial Surgery Unit at the Royal Children's Hospital of Melbourne have been selected for review. Illustrative case reports to highlight the principles of management are presented.- - - - - - - - - - ranking = 0.63717619782287keywords = jaw (Clic here for more details about this article) |
9/27. Juvenile ossifying fibroma of the mandible.Juvenile ossifying fibroma is a benign, but potentially aggressive, fibro-osseous tumor of the craniofacial bones. The authors describe a case of a mandibular juvenile ossifying fibroma presenting in a 14-year-old boy in conjunction with congenitally missing teeth and review the histology, clinical behavior, and management of these uncommon but disfiguring lesions.- - - - - - - - - - ranking = 4keywords = mandible (Clic here for more details about this article) |
10/27. Juvenile aggressive cemento-ossifying fibroma. A case report.Juvenile Aggressive Cemento-Ossifying fibroma is a benign, fibro osseous neoplasm commonly affecting maxilla but also other bones including mandible, arising in children. It is considered to be a locally aggressive and quickly expansile lesion. Because of its aggressive nature and high recurrence rate, an early detection and a complete surgical excision is essential. A case of Juvenile Aggressive Cemento-Ossifying fibroma in a 9 year old male child who visited the Department of oral medicine and radiology, J.S.S. Dental College and Hospital, Mysore is being reported and discussed.- - - - - - - - - - ranking = 1keywords = mandible (Clic here for more details about this article) |
