Final answer:
Actinic Keratosis appears as rough, scaly patches on the skin that can be tan, pink, or red in color. These patches are precancerous and can potentially develop into skin cancer, notably squamous cell carcinoma.
Step-by-step explanation:
Actinic Keratosis is a condition characterized by rough, scaly patches on the skin caused by extensive exposure to the ultraviolet (UV) rays of the sun. These patches can occur in various colors, commonly being tan, pink, or red. As actinic keratoses are considered precancerous growths that can potentially develop into squamous cell carcinoma, which affects the keratinocytes in the stratum basale layer of the skin, they are important indicators for potential skin cancer and warrant medical attention. Critical thinking and awareness of changes in skin pigmentation are essential for identifying such conditions early and seeking appropriate treatment.
