Malignant mesenchymal tumor arising from cherubism: a case report

Craniofacial and Dental Features in Six Children With Cherubism

Cherubism is an autosomal-dominant benign bone disorder, characterized by fibro-osseous lesions in the mandible and maxilla commonly caused by mutations in the SH3-binding protein 2-gene. The purpose of the authors' study was to analyze craniofacial and dental features of children diagnosed with cherubism, describe their treatment, and assess their dental age compared with norms for Finnish children. Six children were diagnosed, followed up and treated due to dental and skeletal disorders caused by cherubsim. The patients were followed up for an average of 91.5 months with emphasis on the skeletal changes and development of dentition. The treatment consisted of minor orthodontic treatment, dental extractions, and exposures. One patient underwent cosmetic mandibular surgery. All patients had lesions in the lower jaw and 5 of 6 patients had lesions in the maxilla as well. The patients were characterized by varying swelling of the jaws, premature loss of deciduous teeth in the affected area and widely spaced, displaced, un-erupted, or absent permanent teeth. The dental age was delayed at younger age but near to normal or even a little ahead at older age. Even though cherubism affects the jaws, jaw positions, and malocclusion, no common dentofacial proportions associated with the disease could be confirmed by cephalometric analysis. The surgical interventions did not provoke adverse reactions or local growth of the lesions.

Case Report of Nonfamilial Cherubism in a Toddler: Description of Clinic-Radiographic Features and Osseous-Dental Treatments

Cherubism is a rare familial disease that occurs between the ages two and five years and regresses after puberty. Most of the cherubism cases show familial history, but there are some cases without familial histories of disorder. A two-year-old boy with a painless symmetrical progressive swelling of the jaws had visited maxillofacial radiology department. Panoramic radiograph revealed well-defined multilocular, radiolucent areas of both jaws. Computed tomography of the jaws showed well-defined, bilateral, multilocular, expansile lesions with thinning of cortical plate of maxilla and mandible and displacing the unerupted first molar anteriorly. Clinical, radiologic, and histopathologic characteristics confirmed the diagnosis of cherubism.

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.

Cherubism: best clinical practice

Cherubism is a skeletal dysplasia characterized by bilateral and symmetric fibro-osseous lesions limited to the mandible and maxilla. In most patients, cherubism is due to dominant mutations in the SH3BP2 gene on chromosome 4p16.3. Affected children appear normal at birth. Swelling of the jaws usually appears between 2 and 7 years of age, after which, lesions proliferate and increase in size until puberty. The lesions subsequently begin to regress, fill with bone and remodel until age 30, when they are frequently not detectable.

Fibro-osseous lesions, including those in cherubism have been classified as quiescent, non-aggressive and aggressive on the basis of clinical behavior and radiographic findings. Quiescent cherubic lesions are usually seen in older patients and do not demonstrate progressive growth. Non-aggressive lesions are most frequently present in teenagers. Lesions in the aggressive form of cherubism occur in young children and are large, rapidly growing and may cause tooth displacement, root resorption, thinning and perforation of cortical bone.

Because cherubism is usually self-limiting, operative treatment may not be necessary. Longitudinal observation and follow-up is the initial management in most cases. Surgical intervention with curettage, contouring or resection may be indicated for functional or aesthetic reasons. Surgical procedures are usually performed when the disease becomes quiescent. Aggressive lesions that cause severe functional problems such as airway obstruction justify early surgical intervention.

Cherubism: case report with review of literature

Cherubism is a rare hereditary fibro-osseous lesion characterized by painless expansion of jaws in childhood and is known to regress without treatment after puberty. Wait and watch approach has been advocated by many authors. The disease starts early in life manifesting itself fully in the second decade of life and is almost regressed in the third decade. Here, we report two cases of cherubism with clinico-radiographic presentation of its classical features in their third and fourth decade of life respectively and review the literature.

Cherubism combined with epilepsy, mental retardation and gingival fibromatosis (Ramon syndrome): a case report

Cherubism is an inherited, autosomal dominant disorder that characteristically affects the jaws of children. The disease typically manifest as a bilateral swelling with associated submandibular lymph node enlargements and usually regresses as age advances. The disease is microscopically indistinguishable from other giant cell lesions and is essentially a clinical diagnosis. The association of cherubism with gingival fibromatosis, epilepsy, mental retardation, stunted growth, and hypertrichosis is referred as Ramon syndrome. We report a case of Ramon syndrome in an 8 year old girl.

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.

Le chérubisme : à propos d’une nouvelle observation avec revue de la littérature

OBJECTIVES

To evaluate radiological characteristics of cherubism.

MATERIAL AND METHODS

We report the case of a 7-year-old boy presented with facial deformity, bilateral mandibular swellings, right exophthalmia and dislocated teeth. Panoramic radiograph, Computed tomography scan and MR imaging were performed.

RESULTS

Panoramic radiograph revealed multiloculated osteolysis involving the entire mandible and the right maxilla with dislocated teeth. Computed tomography scan showed multicystic expansive bony masses without cortical disruption occupying the mandible and right maxilla with extension to the orbital floor. On MR, these lesions demonstrated intermediate inhomogeneous signal intensity on T1 and T2 weighted images with high enhancement after gadolinium administration. MRI was useful in identifying orbital involvement. These clinical and radiological findings are in favor of the diagnosis of cherubism.

CONCLUSION

Cherubism is a rare hereditary benign lesion of the mandible that appears in childhood as bilateral painless swellings which progress until puberty, then spontaneously regress. Plain radiographs and computed tomography scan are sufficient for diagnosis. MR imaging is useful to study the expansion to soft tissues, in particular in the aggressive forms, and establish preoperative vascular assessment. The treatment is plastic and aims to correct the facial deformities.
