Cherubism with multiple dental abnormalities: a rare presentation.

Area of Science:

• Genetics and Developmental Biology
• Oral and Maxillofacial Pathology

Background:

• Cherubism is a rare, hereditary fibro-osseous lesion affecting only the jaw bones.
• It results from abnormal osteoblast and osteoclast activity, replacing normal bone with fibrous tissue and immature bone.

Observation:

• The condition leads to painless, progressive jaw growth, causing a characteristic rounded facial appearance.
• Lesions typically manifest early in life, symmetrically affecting one or both jaws.
• Growth continues until puberty, after which spontaneous regression occurs in most cases.

Findings:

• The underlying pathology involves the replacement of normal bone with cellular fibrous tissue and immature bone.
• The characteristic "cherubic" facial appearance is due to jaw hypertrophy.

Implications:

• Understanding cherubism's genetic basis is crucial for diagnosis and management.
• While often self-limiting, surgical intervention may be necessary for cosmetic reasons in some patients.
