Oral juvenile xanthogranuloma: An unusual presentation in an adult patient and a systematic analysis of published cases

Abstract

Objective: The purpose of this study was to describe an unusual case of intraoral juvenile xanthogranuloma (JXG) and to perform a systematic review to investigate the available literature regarding oral JXGs.

Study design: We present a new case of oral JXG arising in a 36-year-old Italian woman and conducted a systematic literature review in PubMed, Web of Science, and Scopus, according to the PRISMA guidelines.

Results: Our review of the English-language literature yielded 34 cases of oral JXG, which included our case report.

Conclusions: JXG is a non-Langerhans cell histiocytosis. Oral JXG has been reported, but it is a rare manifestation. Because of the rarity of oral lesions and possible variations in the clinical and histologic presentation, the correct diagnosis can be challenging, requiring a careful clinical and histopathologic evaluation with adjuvant immunohistochemical studies.
