Resumo: Oral verruciform xanthoma (VX) is a benign lesion of unknown etiology, usually found in gingiva and palate. Here, we report two cases of this uncommon lesion. The first one is a nodule in the upper gingiva of an adult man, with the clinical diagnosis of squamous papilloma. The second one is a white plaque in the tongue of a 64-year-old man, clinically diagnosed as leukoplakia or reactive hyperkeratosis. After excisional biopsy, both lesions presented as a proliferation of squamous epithelium, with elongated rete ridges and numerous foamy macrophages (CD68+) within connective tissue papillae, classified respectively as flat and verrucous type. The first patient was lost during follow up, but the second showed no signs of recurrence one year after the biopsy. In a 60-year period, we have only 4 cases of VX (0.025%), a lesion that could be clinically misguided as other papillary or verrucous lesions.
