Xanthogranuloma of the oral cavity in adult. A case report and review of the literature.

A case of xanthogranuloma arising in the palatal gingiva of the maxilla in a 38-year-old Japanese male was investigated. Histopathological findings of the excised lesion were indistinguishable from the xanthogranulomas in infants and children (juvenile xanthogranuloma), and like those in the young, the present case was not associated with abnormalities of serum lipids and was not associated with other lesions. A review of the English literature yielded only two histopathologically documented cases of xanthogranuloma in the oral cavity, arising in young patients. A case of xanthogranuloma of oral cavity in an adult was not documented previously.
