C.E. Credit. Xanthogranuloma of the Palate in an Adult: A Case Report with Differential Diagnosis

Abstract

ABSTRACTBackground Solitary oral mucosal xanthogranuloma, previously termed juvenile xanthogranuloma, is exceedingly rare in adults. Extracutaneous lesions are similarly rarely seen; and the condition generally affects infants and children.Methods This case report documents only the second occurrence of an adult oral xanthogranuloma on the palatal mucosa. For the clinician, a differential diagnosis is presented to include several disease categories, including traumatic, infectious/inflammatory, and neoplastic.Conclusions General dentists, dental specialists, and pathologists should be cognizant of this disease, and xanthogranuloma should be considered in the differential diagnosis of benign tumors of the palatal and oral mucosa, especially when a histiocytic entity is being considered.Practical Implications Dentists, dermatologists, and general practitioners may be the first to recognize this rare condition during inspection of the oral cavity.Continuing Education Credit Available: The practice worksheet is available online in the supplemental material tab for this article.A CDA Continuing Education quiz is online for this article: https://www.cdapresents360.com/learn/catalog/view/20
