Which skin lesions are directly related to chronic sun exposure?

Actinic keratosis is directly related to chronic sun exposure and is characterized by rough, scaly patches on sun-exposed areas of the skin, such as the face, ears, neck, and backs of the hands. It results from damage to the skin's keratinocytes due to ultraviolet (UV) radiation from the sun. The condition is considered a precancerous lesion, as prolonged sun exposure can lead to skin cancers, particularly squamous cell carcinoma.

In contrast, seborrheic keratosis, while common in older adults, is not necessarily associated with sun exposure but rather is a benign growth that may occur due to aging or genetic factors. Angiomas are benign vascular lesions that appear as small, red spots on the skin and are not related to UV exposure. Skin tags are benign growths that occur due to friction and are also not linked to sun exposure. Thus, actinic keratosis is the only lesion among the choices that is a direct consequence of chronic sun exposure, highlighting the importance of protecting the skin from UV damage.
