Resumo (EN)

To describe a clinical case of verruciform xanthoma, presenting its main clinical and histopathological characteristics, treated with surgical excision. For the execution of this article, a literature review was conducted by selecting relevant articles on the subject and following the clinical case. The patient visited the Interdisciplinary Dentistry Clinic of UNIP Indianópolis (São Paulo - SP), complaining about the aesthetics of their teeth. During the anamnesis, the patient denied any underlying disorders, pathologies, or allergies. Upon intraoral examination, highly inflamed gums, some crowns destroyed by dental caries, and a sessile lesion with papillary appearance and yellowish coloration, approximately 3mm in size, were identified in the gingival region below tooth 42, accompanied by edema. The patient reported no symptoms in the region. No radiographic alterations were detected in the lesion. After three months, the patient returned to the clinic for residual root extractions. On this occasion, an excisional biopsy of the lesion was also performed, with the collected sample sent for histopathological analysis, confirming compatibility with verruciform xanthoma. It can be concluded that verruciform xanthoma is a rare lesion that requires excisional biopsy for accurate diagnosis. The prognosis is favorable, with no recurrence or malignant transformation observed. Removal is recommended for proper diagnosis.
