What is chronic actinic dermatitis?
Chronic actinic dermatitis is a rare skin condition that mainly affects men over the age of 50 years. It is characterised by severely itchy, red, inflamed, and thickened dry skin, mainly in areas that have been exposed to sunlight or artificial light. The condition is also known as chronic photosensitivity dermatitis and actinic reticuloid (this name comes from the histological findings of skin biopsies which resemble a reticulosis or cutaneous T-cell lymphoma).
