Chronic actinic dermatitis (CAD) is a photosensitivity disorder characterized by eczema-like skin changes that occur in response to ultraviolet radiation (UVR) exposure. It is also known as actinic reticuloid or photosensitivity dermatitis.
Signs and Symptoms[edit]
Patients with chronic actinic dermatitis typically present with pruritus (itching), erythema (redness), and lichenification (thickening of the skin) in sun-exposed areas. The condition may resemble eczema and can lead to significant discomfort and skin damage over time.
Causes[edit]
Chronic actinic dermatitis is caused by an abnormal skin reaction to ultraviolet radiation, particularly UVB and UVA rays. The exact mechanism is not fully understood, but it involves an immune-mediated response to sunlight. Risk factors include prolonged sun exposure and the use of photosensitizing agents such as certain medications and chemicals.
Diagnosis[edit]
Diagnosis of chronic actinic dermatitis involves a combination of clinical evaluation, phototesting, and biopsy of affected skin. Phototesting helps determine the specific wavelengths of light that trigger the condition, while a biopsy can rule out other skin disorders.
Treatment[edit]
Management of chronic actinic dermatitis focuses on photoprotection and reducing skin inflammation. Patients are advised to avoid sun exposure and use broad-spectrum sunscreens. Topical corticosteroids are commonly prescribed to reduce inflammation, and immunosuppressants may be used in severe cases.
Prognosis[edit]
Chronic actinic dermatitis is a long-term condition that requires ongoing management. With appropriate treatment and sun avoidance, symptoms can be controlled, although complete resolution is rare. Patients are at an increased risk of developing skin cancer due to chronic sun damage.
