Verruciform xanthoma in association with discoid lupus erythematosus.
Verruciform xanthoma (VX) is an uncommon lesion occurring primarily in the oral cavity. Cutaneous lesions are much less common and they preferentially arise on anogenital skin. They are not necessarily associated with a pre-existing inflammatory process. We report a VX in association with a long-standing lesion of discoid lupus erythematosus (DLE) on the scalp of a 34-year-old black woman. This association, which to our knowledge has not been previously reported, is consistent with the proposed pathogenetic mechanism of entrapment and subsequent degeneration of epithelial cells in the papillary dermis of VX. Histological distinction of VX from squamous cell carcinoma, with which this lesion may be clinically confused, is straightforward.
