What condition may progress from actinic keratosis?

• A. Melanoma
• B. Basal cell carcinoma
• C. Squamous cell carcinoma
• D. Dermatitis

Answer: (C)

Actinic keratosis is a precancerous skin condition that develops due to prolonged sun exposure, leading to the thickening of the outer layer of skin (stratum corneum) with a rough, scaly texture. It is considered a significant risk factor for the progression to squamous cell carcinoma (SCC), which is a type of skin cancer that arises from the squamous cells, commonly found in the epidermis. The transformation from actinic keratosis to squamous cell carcinoma occurs as the DNA damage accumulates in the skin cells, leading to mutations that result in uncontrolled cell growth. While not all actinic keratoses progress to SCC, there is a notable correlation between the two conditions, emphasizing the importance of monitoring and treating actinic keratosis to prevent progression. Regular dermatological evaluation and proactive management can help mitigate this risk. In contrast, melanoma arises from melanocytes, the pigment-producing cells in the skin, rather than squamous cells, making it a less likely progression from actinic keratosis. Basal cell carcinoma primarily develops from basal cells and also does not typically progress from actinic keratosis. Dermatitis is an inflammatory condition of the skin and is not a progression from actinic keratos
