Rare case of large verrucous xanthoma of oral cavity managed with nasolabial flap and review of literature

Abstract

Verruciform Xanthoma (VX) is an rare benign mucocutaneous condition that occurs predominantly in the oral cavity which occasionally affects skin and genitals. It appears as a papule or single plaque showing a verrucous or papillomatous structure, with variable color from reddish pink to gray. In majority of oral cases, it affects gingiva and alveolar mucosa being a solitary lesion. It is often associated with pre-existing epithelial and/or inflammatory disorder and is characterized histopathologically by papillary epithelial hyperplasia and the presence of foamy macrophages in connective tissue papillae. We report a rare case of widespread verrucous xanthoma of gingiva and alveolar mucosa which was managed by wide local excision and defect was reconstructed using nasolabial flap.
