Temporal bone involvement in cherubism: case report

Cherubism: An Unusual Study With Long-Term Follow-Up

Cherubism is an uncommon hereditary benign fibro-osseous disorder characterized by bilateral enlargement of the mandible and the maxilla that presents with varying degrees of involvement and a tendency toward spontaneous remission.The first visit was in 2002. A 16-year-old female was referred to an orthodontist for correction of her dental crowding. In the radiographic examination that was taken for her treatment the first time in 2002, a jaw bone lesion was discovered accidentally. X-ray panoramic imaging revealed well-defined multilocular radiolucencies involving the posterior body of the mandible and ascending rami with displaced teeth. This lesion had no effect on inferior alveolar canal and maxilla.There was no significant past medical history, and there was no family history suggestive of a similar complaint. On extraoral examination, there was no swelling in both rami of the mandible and face. Histopathological examination of the biopsy specimen showed proliferating fibrous connective tissue interspersed by multinucleated giant cells. It was diagnosed as a case nonfamilial cherubism. An extensive long-term follow-up till 12 years was maintained. In 2014, after 12-years follow-up for this lesion, panoramic imaging examination showed progress of this lesion in mandible and maxilla.

Cherubism: A rare case report

Cherubism is a rare congenital disease resulting in malformation of the jaw. It occurs before the age of 5 years and regress spontaneously after puberty. It can result into enlargement of the jaw bone, tooth displacement, facial disfigurement and psychological trauma to patient. Hence, the understanding about the condition, its progression and management is necessary.

Cherubism: a case report of a three-generation inheritance and literature review

Cherubism is a rare, non-neoplastic pathologic entity first described by Jones in 1933. It affects mostly younger individuals and is usually inherited. Cherubism presents as a painless jaw enlargement that affects both the maxilla and the mandible and is characterized by replacement of the osseous tissue by fibrous connective tissue. Radiologically, the lesions appear as multiple, multilocular radiolucent spaces with distinct borders divided by bony septations, which often dramatically alter the shape and size of the jaw structures. These often result in marked facial abnormalities. Cervical lymphadenopathy is not uncommon in those affected. The disease is self-limited and can reverse itself with time. Approximately 250 cases have been reported in published studies, mostly affecting males. The purpose of our report was to present a case of cherubism diagnosed in a young girl and the long-term (3 generations) follow-up evaluation of her mother and grandmother, both of whom had been diagnosed with the same pathologic entity.

Júnior S, Guerreiro N, Cavalcanti MGP. Clinical and imagiological findings of central giant cell lesion and cherubism

Cone beam computed tomography (CBCT) is the best examination for bone lesions of the maxilla, allowing the dentist to evaluate precisely the behavior and components of the lesion and their relationship to the surrounding structures. Central giant cell lesion and cherubism are histologically very similar lesions. Therefore clinical and radiological examinations are fundamentally important for the diagnosis. The aim of this paper is to report two cases diagnosed as central giant cell lesions and cherubism using CBCT. This imaging modality was very important for the diagnosis of the lesions presented in the current study. It also allowed observing precisely the limits of the lesions, the components, the behavior and the exact relationship to adjacent structures.

Identical Mutation in SH3BP2 Gene Causes Clinical Phenotypes with Different Severity in Mother and Daughter - Case Report

Cherubism is a particular form of fibrous dysplasia of the jaws. Familial occurrence was reported in most cases. The condition is a rare hereditary disorder with autosomal dominant inheritance, with complete penetrance in males and incomplete penetrance in females and variable expressivity. It is known to be caused by mutations in the gene encoding SH3-domain binding protein 2, SH3BP2 gene. Major diagnostic criteria are cherubic facial appearance, painless hard enlargement of the jaws, and frequently associated dental abnormalities. The aim of the study was to analyze clinical and genetic features of cherubism in a family with 3 daughters in which the youngest one was affected. Clinical and radiographic examinations, hematological and biochemical evaluations and biopsy were performed. Molecular genetic analysis consisted of PCR amplification and direct sequencing of selected exons of the SH3BP2 gene. Cherubism was suspected based on clinical and radiographic examinations of the 9-year-old daughter. She presented asymmetrical enlargement of the mandible, speech and swallowing problems and dental abnormalities on the lower jaw. There was no history of similar clinical findings in any of the daughters or the parents of the affected girl. Abnormal results were obtained by genetic analysis. A c.1244G>A mutation was identified in exon 9 of the SH3BP2 gene in the asymptomatic mother and her affected daughter. The identified mutation in the SH3BP2 gene is probably disease-causing. The asymptomatic mother transmitted the gene mutation to her affected daughter. Our results confirm the reduced penetrance and variable expression of the gene mutation.

Benign fibro-osseous lesions of the craniofacial complex. A review

Benign fibro-osseous lesions of the craniofacial complex are represented by a variety of disease processes that are characterized by pathologic ossifications and calcifications in association with a hypercellular fibroblastic marrow element. The current classification includes neoplasms, developmental dysplastic lesions and inflammatory/reactive processes. The definitive diagnosis can rarely be rendered on the basis of histopathologic features alone; rather, procurement of a final diagnosis is usually dependent upon assessment of microscopic, clinical and imaging features together. Fibrous dysplasia and osteitis deformans constitute two dysplastic lesions in which mutations have been uncovered. Other dysplastic bone diseases of the craniofacial complex include florid osseous dysplasia, focal cemento-osseous dysplasia and periapical cemental dysplasia, all showing a predilection for African descent individuals; although no specific genetic alterations in DNA coding have yet to be uncovered and most studies have been derived from predominant high African descent populations. Ossifying fibromas are neoplastic lesions with four subtypes varying with regard to behavior and propensity for recurrence after surgical excision. The clinicopathologic and molecular features of this unique yet heterogeneous group of diseases are reviewed.

Aggressive case of cherubism: 17-year follow-up

Cherubism is an autosomal dominant disorder in which the normal bone is replaced by cellular fibrous and immature bone, resulting in painless symmetrical enlargement of the jaws. An aggressive case of cherubism with extensive swelling on several facial bones in a 19-year-old boy is reported. The disorder was diagnosed 15 years ago, but the patient has not been submitted to any type of surgery so far. The highlights of this case are the great proportion of the lesions, the enormous functional and emotional disturbances brought about by these lesions, and the difficulty to choose the most appropriate age and form of treatment.
