Skin disorder. The hand of an elderly woman affected by an infected eczema. This is an inflammation of the skin which causes itching and it is sometimes accompanied by scaling or blisters. Eczema may be caused by an allergy but often occurs for no known reason. For mild cases treatment consists of applying emollients, such as petroleum jelly, which keep the skin in the affected area soft. In severe cases corticosteroid drugs may be prescribed and if, as in this case, bacterial infections develop, antibiotic drugs may be given.
