Non-familial cherubism--a case report.

Area of Science:

• Dentistry
• Genetics
• Pediatrics

Background:

• Cherubism is a rare, benign genetic disorder characterized by progressive, symmetrical, painless enlargement of the jaws.
• Typically presents in early childhood with a familial pattern, though sporadic cases occur.

Observation:

• A 9-year-old boy with no prior family history presented with facial swelling and delayed tooth eruption.
• Clinical examination revealed characteristic facial deformities consistent with cherubism.
• Histologic examination of biopsied tissue showed characteristic fibro-osseous changes.

Findings:

• Radiographic imaging demonstrated bilateral, symmetrical enlargement of the mandible and maxilla with characteristic "cotton-wool" appearance.
• Differential diagnosis included other fibro-osseous lesions and giant cell granulomas.
• Genetic analysis was considered but not performed in this case due to the clear clinical and radiographic presentation.

Implications:

• Early and accurate diagnosis of cherubism is crucial for appropriate management and to prevent complications.
• Understanding the clinical, histologic, and radiographic features aids in differentiating cherubism from other jaw pathologies.
• This case highlights the importance of considering cherubism even in the absence of a positive family history, guiding potential treatment approaches.
