A verruciform xanthoma of the lower lip and review of the differential diagnosis.

A careful examination of lips is often neglected by the members of the medical and dental professions; yet the lips reveal a heterogeneous group of lesions ranging from congenital abnormalities to benign and malignant neoplasms. Verruciform Xanthoma (VX) is an uncommon benign inflammatory mucocutaneous condition that occurs in the oral cavity which was first described by Shafer in 1971. 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 case with VX which presented as a well-defined, soft, painless swelling on the lower lip having different clinical features.
