Actinic keratosis (AK), also known as solar keratosis, is a pre-cancerous skin condition caused by excessive sun exposure. It is characterized by rough, scaly patches on sun-exposed areas such as the face, ears, scalp, neck, and hands. While AK is not cancerous, it can be mistaken for other skin conditions, such as psoriasis, eczema, seborrheic keratosis, and basal cell carcinoma.
Psoriasis is a chronic skin condition characterized by red, scaly patches of skin that can be itchy or painful. It is often mistaken for AK because both conditions involve hard, scaly patches of skin that may be somewhat raised. However, psoriasis is typically not found on the face, neck, or other sun-exposed areas, and is not caused by sun exposure.
Eczema is another skin condition that can be mistaken for AK. It is characterized by red, itchy, and scaly patches of skin, and can be found on the face, neck, and other sun-exposed areas. However, it is usually more widespread than AK, and is not caused by sun exposure.
Seborrheic keratosis is a benign skin growth that is often mistaken for AK because both conditions involve raised, scaly patches of skin. However, seborrheic keratosis is typically more uniform in size and shape, and is not caused by sun exposure.
Basal cell carcinoma (BCC) is a type of skin cancer that can be mistaken for AK because both conditions involve scaly patches of skin. However, BCC is usually more raised and fleshy in appearance, and may have a “pearly” look. Additionally, BCC is more likely to be found on sun-exposed areas than AK.
If you notice any of these skin conditions on your body, be sure to have it evaluated by a dermatologist. A doctor can diagnose and treat the condition, and ensure that it is not a form of skin cancer.
