Abstract
Medical guidelines serve as systematic decision-making aids to ensure evidence-based and appropriate medical management of specific diseases. In Germany, dermatological guidelines are developed under the leadership of the German Dermatological Society (DDG) and the Professional Association of German Dermatologists (BVDD) following the methodology of the Working Group of Scientific Medical Societies (AWMF). In the period 2023-2024, various guidelines in the field of dermatology were revised or newly issued. These include guidelines on the diagnosis and treatment of epidermal necrolysis (Stevens-Johnson syndrome and toxic epidermal necrolysis), atopic dermatitis, hidradenitis suppurativa/acne inversa, cutaneous Lyme borreliosis, primary hyperhidrosis, circumscribed scleroderma, screening for anal dysplasia and anal carcinoma in HIV-infected individuals, aphthae and aphthous lesions of the oral and pharyngeal mucosa, and allergological diagnostics of hypersensitivity reactions to drugs. Additionally, updates were published on basal cell carcinoma of the skin, anal pruritus, anal eczema, actinic keratosis and squamous cell carcinoma of the skin, bee and wasp venom allergy, and hand eczema. This review summarizes the key recommendations and recent updates in dermatological guidelines.
