Basal Cell Carcinoma Arising within a Fibroepithelial Polyp: A Case Report

Basal cell carcinoma (BCC) is the most common cancer both worldwide and in the United States. Approximately 4.3 million cases of BCC are diagnosed in the United States each year [1]. It typically arises on sun-damaged skin, the majority being on the head and neck, though cases on the trunk and lower extremities are not uncommon. Independent risk factors for developing BCC include ultraviolet light exposure, light-colored skin, age, male sex, exposure to arsenic, radiation, previous skin cancer, and inherited conditions such as xeroderma pigmentosum and basal cell nevus syndrome [1]. Two main characteristics distinguish superficial BCC on histology: Basal cell buds with peripheral palisading arising from the basal layer of the epidermis, and retraction artifact [2].
