[Diagnosis and management of chronic hand eczema in practice]

Chronic hand eczema is a common inflammatory skin disease that significantly impairs quality of life and affects approximately 10 % of the population. Common causes include occupational exposure to chemicals or wet work (irritant or allergic contact dermatitis) as well as endogenous factors such as atopic diathesis. Diagnosis is based on medical history, clinical examination, and, if necessary, further testing (e. g., patch testing). Treatment involves a holistic approach consisting of avoidance of triggers, intensive skin care and the application of topical corticosteroids, calcineurin inhibitors, or newer treatments such as topical JAK inhibitors. In severe cases, systemic therapies may be necessary. Early diagnosis and treatment are essential to prevent chronicity, improve patients' quality of life, and maintain their ability to work.
