A1 - Mikailov, Anar Y1 - 2023 N1 - T2 - Fitzpatrick’s Color Atlas and Synopsis of Clinical Dermatology, 9e AB - Cutaneous epithelial cancers (nonmelanoma skin cancer [NMSC]) originate most commonly in the epidermal germinative keratinocytes or adnexal structures. The two principal NMSCs are basal cell carcinoma (BCC) and squamous cell carcinoma (SCC). SCC often has its origin in an identifiable in situ lesion that can be treated before frank invasion occurs. In contrast, in situ BCC is not known, but minimally invasive “superficial” BCCs are common.
