Squamous cell carcinoma developing in a long-standing case of tuberous xanthoma: An incident unreported hitherto

摘要

Cutaneous squamous cell carcinoma, characterized by malignant transformation of normal epidermal keratinocyte is the second most common nonmelanoma skin cancer that has many predisposing factors. Tuberous xanthomas have not yet been reported as a predisposing factor. We report here the case of long-standing tuberous xanthoma in a middle-aged gentleman complicated by cutaneous squamous cell carcinoma, probably the first such report in the Indian literature.
