<\/span>What is it cutaneous<\/span> scaly<\/span> cell carcinoma<\/span>?<\/span><\/h2>\nCutaneous squamous cell carcinoma (SCC) is a common type of keratinocytes<\/span> Cancer<\/span>or notmelanoma<\/span> skin cancer. It is derived from cells within the epidermis<\/span> that does curb<\/span> \u2013 the horny protein that forms the skin, hair<\/span> and nail<\/span>.<\/p>\nCutaneous SCC is a invader<\/span> disease, which refers to cancer cells that have grown beyond the epidermis. SCC can sometimes metastasis<\/span> and it can be fatal<\/p>\nIntraepidermal<\/span> carcinoma (SCC cutaneous in the place<\/span>) and mucous membrane<\/span> SCC are considered elsewhere.<\/p>\n<\/span>Who gets cutaneous squamous cell carcinoma?<\/span><\/h2>\nRisk factors for cutaneous SCC include:<\/p>\n
\n- age and sex<\/span>: CECs are particularly predominant<\/span> in older men. However, they also affect women and younger adults.<\/li>\n
- Previous SCC or another form of skin cancer (basal<\/span> cell carcinoma, melanoma) are a strong predictor of future skin cancers.<\/li>\n
- Actinic keratosis<\/span><\/span><\/li>\n
- Outdoor occupation or recreation<\/li>\n
- Of smoking<\/li>\n
- Fair skin, blue eyes, and blonde or red hair.<\/li>\n
- Previous skin injury, thermal burn, disease (eg, cutaneous lupus, epidermolysis bullosa, leg ulcer<\/span>)<\/li>\n
- Hereditary syndromes: SCC is a particular problem for families with xeroderma pigmentosum and albinism.\n<\/li>\n
- Other risk factors include ionizing radiation, exposure to arsenic, and immunosuppression<\/span> due to illness (eg. chronic<\/span> lymphocytic<\/span> leukemia<\/span>) or medications. Organ transplant<\/span> Recipients are at massive risk of developing SCC.<\/li>\n<\/ul>\n
<\/div>\n
<\/span>What Causes Cutaneous Squamous Cell Carcinoma?<\/span><\/h2>\nMore than 90% of SCC cases are associated with numerous DNA<\/span> mutations<\/span> in multiple somatic<\/span> genes<\/span>. Mutations in p53 tumor<\/span> suppressor gene<\/span> are caused by exposure to Ultraviolet radiation<\/span> (UV<\/span>), especially UVB (known as signature 7). Other characteristic mutations are related to smoking, aging, and immune suppression (for example, with drugs such as azathioprine). Mutations in signaling pathways affect epidermal<\/span> growth factor<\/span> receiver<\/span>, RAS, Fyn and p16INK4a signaling. <\/p>\nBeta-genus human papillomaviruses (wart viruses) are thought to play a role in SCC arising in immunocompromised populations. \u03b2-HPV and HPV 5, 8, 17, 20, 24, and 38 subtypes have also been associated with an increased risk of cutaneous SCC in immunocompetent individuals. <\/p>\n
<\/span>What are the clinical features of cutaneous squamous cell carcinoma?<\/span><\/h2>\nCutaneous SCC present as enlargement scaly<\/span> or crusty lumps. They usually arise within pre-existing actinic keratosis<\/span><\/span> or intraepidermal carcinoma.<\/p>\n\n- They grow for weeks or months.<\/li>\n
- They can ulcerate<\/li>\n
- They are often tender or painful.<\/li>\n
- Located on sun-exposed sites, particularly the face, lips, ears, hands, forearms, and legs<\/li>\n
- The size varies from a few millimeters to several centimeters in diameter.<\/li>\n<\/ul>\n\n
