Oral verruciform xanthomas mimicking potentially malignant disorders

Verruciform xanthoma represents a reactive lesion, common in the skin and somewhat rare in the mouth. Cases description: Two cases of verrucous white plaques, located on the tongue and the floor of mouth of different 30-years-old man and woman and clinically diagnosed as leukoplakia, are described. The histopathological analyses confirmed the diagnosis of oral verruciform xanthomas for both lesions. Practical implications: Despite of uncommon in the oral cavity, the verruciform xanthoma, particularly when affecting regions with a higher risk of developing oral cancer, should be included in differential diagnosis of oral potentially malignant disorders. The histopathological analysis remains as "gold standard technique" for a more accurate diagnosis of oral verruciform xanthoma. Key words:Foam cells, Verruciform xanthoma, Leukoplakia, Tongue.
