Hand eczema, one of the most common skin conditions affecting the hands, is also the most common type of skin disease related to work. Typically, only severe cases are diagnosed in dermatology clinics, as patients seldom seek help for early hand dermatitis. Mild cases are usually identified during routine occupational screenings. Hand eczema can become a long-lasting condition, persisting even after avoiding contact with the substance that triggers it. Key risk factors for hand eczema include a personal or family history of atopy, exposure to wet conditions, and contact with allergens. Studies show a higher prevalence of hand eczema among women, especially younger women in their twenties, likely due to environmental factors.
