What type of skin lesion is commonly associated with sun damage?

1. Acne vulgaris

2. Actinic lentigines

3. Psoriasis

4. Dermatitis

The correct answer is: Actinic lentigines

Actinic lentigines, also known as "sun spots" or "liver spots," are flat, brown, or tan lesions that develop on areas of the skin that have been exposed to the sun over time. They result from prolonged ultraviolet (UV) radiation exposure, which leads to an increase in melanin production and localized hyperpigmentation. These lesions are a clear indicator of sun damage and are commonly found on the face, hands, shoulders, and arms—areas that typically receive the most sun exposure. In contrast, other conditions listed do not have a direct correlation with sun exposure. Acne vulgaris is primarily related to hormonal changes and clogged pores rather than sun damage. Psoriasis is an autoimmune condition that leads to rapid skin cell turnover, resulting in scaling and inflammation, but is unrelated to UV exposure. Dermatitis encompasses a variety of inflammatory skin conditions, often triggered by irritants or allergens, and does not specifically relate to sun-induced damage. Thus, actinic lentigines specifically highlight the impact of UV exposure on skin health.
