title: Hand dermatitis--differential diagnoses, diagnostics, and treatment options.
abstract: The pathogenesis of hand dermatitis is multifactorial, and includes factors such as genetic predisposition and exposure. A high incidence rate is associated with female gender, contact allergy, atopic dermatitis, and wet work. The most important risk factors for the persistence of hand dermatitis include its extent, contact allergic or atopic etiology, childhood dermatitis, and early onset (before the age of 20). The cost of illness of hand dermatitis corresponds to this seen in moderate to severe psoriasis. The diagnostic workup of hand dermatitis and its differential diagnoses requires a detailed assessment of occupational and recreational exposure. In case of possible work-related triggers, early notification of the accident insurer should be sought (via the dermatologist's report). Exposure to a contact allergen is a contributing factor in one-half of all cases of hand dermatitis. It is therefore imperative that all patients with hand dermatitis persisting for more than three months undergo patch testing. Successful and sustainable treatment of hand dermatitis starts with the proper identification and elimination of individual triggers, including the substitution of identified contact allergens and irritants, as well as optimizing preventive measures. Graded therapy taking the clinical severity into account is essential. Validated instruments may be used to monitor therapeutic efficacy.
