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 .
Cutaneous squamous-cell carcinoma; Other names: Squamous-cell carcinoma of the skin, squamous-cell skin cancer, epidermoid carcinoma, squamous-cell epithelioma of the skin: Cutaneous squamous-cell carcinoma tends to arise from actinic keratoses (premalignant lesions); surface is usually scaly and often ulcerates (as shown here). Specialty
A431 cells were established from an epidermoid carcinoma in the skin of an 85- year-old female patient. Epidermal growth factor (EGF) stimulation of A431 cells induces rapid tyrosine phosphorylation of intracellular signaling proteins which control cellular processes such as growth, proliferation and apoptosis.
Mucoepidermoid carcinoma (MEC) [1] is the most common type of minor salivary gland malignancy in adults. Mucoepidermoid carcinoma can also be found in other organs, such as bronchi , lacrimal sac , [ 2 ] and thyroid gland .
Other modalities of treatment such as photodynamic therapy, epidermal radioisotope therapy, [61] topical chemotherapy, electrodesiccation and curettage can be found in the discussions of basal-cell carcinoma and squamous-cell carcinoma.
Conjunctival squamous cell carcinoma (conjunctival SCC) and corneal intraepithelial neoplasia comprise ocular surface squamous neoplasia (OSSN). SCC is the most common malignancy of the conjunctiva in the US, with a yearly incidence of 1–2.8 per 100,000.
Carcinoma is a malignancy that develops from epithelial cells. [1] Specifically, a carcinoma is a cancer that begins in a tissue that lines the inner or outer surfaces of the body, and that arises from cells originating in the endodermal, mesodermal [2] or ectodermal germ layer during embryogenesis.
Squamous anal carcinoma, extensive perianal spread. Most anal cancers are squamous cell carcinomas (epidermoid carcinomas), that arises near the squamocolumnar junction. It may be keratinizing (basaloid) or non-keratinizing (cloacogenic). [17]
