what is superficial squamous cell carcinoma
What is intraepidermal squamous cell carcinoma? Intraepidermal squamous cell carcinoma (SCC) is a common superficial form of skin cancer. It is also known as Bowen disease, intraepidermal carcinoma (IEC) and carcinoma in situ (SCC in situ). Intraepidermal SCC is derived from squamous cells, the flat epidermal cells that make keratin âthe horny protein that makes up skin, hair and nails. âIntraepidermalâ and âin situâ mean the malignant cells are confined to cell of origin, that is, the epidermis.
