Hand eczema in medical terms refers to eczema of the hands, with signs and symptoms such as redness, blisters, dryness, itchiness, and scaling on the hands. Hand eczema may be related to genetics, infections, hormone levels and other factors. The main manifestations are redness and blisters on the fingers and palms of the hands, and the blisters may also become flaky when they dry. Eczema on the hands may also be characterized by dry, cracked and hyperkeratotic skin, which may lead to damage to the stratum corneum or thickened, mossy skin, which in turn affects the curvature and dexterity of the hands and fingers. Some people with hand eczema may also experience varying degrees of itching. If the above symptoms and manifestations occur, it is usually considered to be caused by hand eczema, and it is recommended to go to a regular hospital in time for examination and treatment as prescribed by the doctor.
