Actinic keratosis (AK) and squamous cell carcinoma (SCC) are two common skin conditions that share some similarities. Both are caused by prolonged exposure to Ultraviolet (UV) radiation, and both can have a scaly, red rash. However, there are some distinct differences between the two conditions that must be noted in order to correctly diagnose and treat them.
Actinic keratosis is a pre-cancerous condition that appears as rough, scaly patches on the skin. It is most commonly found on areas of the body that have had prolonged exposure to UV radiation, such as the face, ears, chest, and hands. AK is not usually cancerous, but it can develop into skin cancer if left untreated. Treatment for AK usually involves topical medications, cryotherapy, or laser therapy.
Squamous cell carcinoma is a type of skin cancer that can develop from AK if it is not treated. It appears as a firm, red bump with scaly patches. It is most commonly found on areas that have had prolonged UV exposure, such as the face, ears, neck, and hands. Treatment for SCC usually involves surgery, radiation therapy, or chemotherapy.
To differentiate between actinic keratosis and squamous cell carcinoma, it is important to look for certain signs. AK typically appears as rough, scaly patches on the skin, while SCC appears as a firm, red bump with scaly patches. In addition, AK is generally not cancerous, while SCC is considered a type of skin cancer. It is also important to note that AK can progress to SCC if not treated, so it is important to diagnose and treat AK as soon as possible.
