Solar Keratosis

Solar Keratosis (also known as Actinic Keratosis) is a common skin condition characterized by rough, scaly patches on the skin resulting from long-term exposure to the sun. These patches are considered precancerous, as they have the potential to develop into squamous cell carcinoma, a type of skin cancer. Solar keratoses are most commonly found on areas of the body that are frequently exposed to the sun, such as the face, ears, neck, scalp, chest, backs of hands, forearms, and lips.

Causes and Risk Factors

The primary cause of Solar Keratosis is prolonged and repeated exposure to ultraviolet (UV) radiation from the sun or artificial sources, such as tanning beds. The risk of developing actinic keratosis increases with age, as the cumulative exposure to UV radiation increases over time. Other risk factors include having fair skin, light-colored eyes, red or blonde hair, a history of sunburns, a weakened immune system, and living in sunny or high-altitude climates.

Symptoms

Solar Keratosis lesions appear as rough, scaly patches that may be pink, red, or the same color as the skin. They can also be sensitive or painful when touched. The size of the lesions can vary, and they may merge together to form larger areas of affected skin.

Diagnosis

Diagnosis of Solar Keratosis is typically made by a dermatologist through a physical examination of the skin. In some cases, a skin biopsy may be performed to rule out skin cancer by examining the tissue under a microscope.

Treatment

Treatment options for Solar Keratosis include topical medications, cryotherapy (freezing the lesions with liquid nitrogen), photodynamic therapy, chemical peels, and laser therapy. The choice of treatment depends on the number, size, and location of the lesions, as well as the patient's overall health.

Prevention

Prevention of Solar Keratosis involves protecting the skin from UV radiation. This includes wearing sunscreen with a high SPF, wearing protective clothing, avoiding sun exposure during peak hours, and avoiding the use of tanning beds.

Prognosis

With proper treatment, the prognosis for Solar Keratosis is generally good. However, individuals with actinic keratosis have an increased risk of developing skin cancer, so regular skin examinations by a healthcare professional are recommended.
