Compared to basal cell carcinoma, cSCC is more likely to spread to distant areas. [11] When confined to the epidermis, the outermost layer of the skin, the pre-invasive or in situ form of cSCC is termed Bowen's disease. [12] [13] The most significant risk factor for cSCC is extensive lifetime exposure to ultraviolet radiation from sunlight. [2]
The term carcinoma in situ may be used interchangeably with high-grade SIL. [8] Ductal carcinoma in situ of the breast is the most common precancer in women. Bowen's disease is a squamous carcinoma in situ of the skin. Colon polyps often contain areas of CIS that will almost always transform into colon cancer if left untreated.
Sometimes, the term "precancer" is also used for carcinoma in situ, which is a noninvasive cancer that has not grown and spread to nearby tissue, unlike the invasive stage. As with other precancerous conditions, not all carcinoma in situ will become an invasive disease but is at risk of doing so.
Squamous cell carcinoma, melanoma in situ, Pagetoid Bowen's disease, ocular sebaceous carcinoma, and other carcinomas can all display pagetoid growth. The term pagetoid (i.e., 'Paget-like') is derived from the extramammary Paget's disease, wherein the large tumour cells are arranged singly or in small clusters within the epidermis and its ...

Squamous-cell carcinoma (SCC), also known as epidermoid carcinoma, comprises a number of different types of cancer that begin in squamous cells. [1] These cells form on the surface of the skin, on the lining of hollow organs in the body, and on the lining of the respiratory and digestive tracts .
High-grade PIN (carcinoma in situ—Bowen's disease, Erythroplasia of Queyrat and bowenoid papulosis (BP)); Invasive carcinoma of the penis. However, in some cases, non-dysplastic or mildly dysplastic lesions may progress directly into cancer. Examples include flat penile lesions (FPL) and condylomata acuminata. [4]
