Actinic prurigo

Actinic Prurigo (pronounced: ak-tin-ik proo-ri-go) is a rare, chronic skin condition characterized by an intense reaction to sunlight. The term "Actinic" is derived from the Greek word "aktis" meaning ray, referring to the sun's rays, and "Prurigo" is derived from the Latin word "prurire" which means to itch.

Definition

Actinic Prurigo is a type of photodermatosis, a group of conditions in which sunlight triggers skin disorders. It is characterized by itchy, red bumps and blisters that appear on the skin after exposure to sunlight. The condition is more common in people of Native American descent, particularly those from Central and South America.

Symptoms

The primary symptom of Actinic Prurigo is an intense itching sensation on the skin, followed by the appearance of red, inflamed bumps or blisters. These lesions typically appear on areas of the skin that are exposed to the sun, such as the face, neck, and hands. However, they can also appear on areas that are usually covered, such as the arms and legs.

Causes

The exact cause of Actinic Prurigo is unknown, but it is believed to be an abnormal immune response to sunlight. It is more common in individuals with a family history of the condition, suggesting a genetic component.

Treatment

Treatment for Actinic Prurigo typically involves measures to protect the skin from sun exposure, such as wearing protective clothing and using sunscreens. Medications, such as topical corticosteroids and antihistamines, may also be used to manage symptoms. In severe cases, systemic therapies such as immunosuppressants may be required.
