Cutaneous squamous-cell carcinoma (cSCC), also known as squamous-cell carcinoma of the skin or squamous-cell skin cancer, is one of the three principal types of skin cancer, alongside basal-cell carcinoma and melanoma. [10] cSCC typically presents as a hard lump with a scaly surface, though it may also present as an ulcer. [1]
Basal-cell skin cancer (BCC), squamous-cell skin cancer (SCC), melanoma [1] Causes: Ultraviolet radiation from the Sun or tanning beds [4] Risk factors: Light skin, poor immune function [1] [5] Diagnostic method: Tissue biopsy [3] Prevention: Decreasing exposure to ultraviolet radiation, sunscreen [6] [7] Treatment: Surgery, radiation therapy ...

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 .
[63] [64] Lichen sclerosus is associated with from 3 to 7% of all cases of vulvar squamous cell carcinoma. [65] In women, it has been reported that 33.6 times higher vulvar cancer risk is associated with LS. [66] [67] A study in men noted that: "the reported incidence of penile carcinoma in patients with balanitis xerotica obliterans is 2.6–5 ...
Melanoma is a type of skin cancer that is often caused by exposure to ultraviolet light, which can be found in sunlight as well as tanning lamps and beds, according to Mayo Clinic. Skin on the ...
All squamous cell carcinoma lesions are thought to begin via the repeated, uncontrolled division of cancer stem cells of epithelial lineage or characteristics. Accumulation of these cancer cells causes a microscopic focus of abnormal cells that are, at least initially, locally confined within the specific tissue in which the progenitor cell resided.
Carcinoma-in-situ is a precursor lesion of squamous cell cancer that does not invade through the basement membrane. There are two types of precursor lesions: Usual-type vulvar intraepithelial neoplasia (uVIN), which is associated with human papillomavirus (HPV) and often affects younger women. This precursor lesion progresses to basaloid or ...
