A rash is a change in the skin due to skin irritation. Most rashes go away on their own or require only minor treatment. Some rashes may need medical attention. Some rash symptoms are redness, itching, bumps, redness, and swelling. Some causes of rashes are allergic reactions; plants such as poison ivy; or irritation due to jewelry, chemicals, or makeup.

A variety of treatment modalities are commonly employed, with varying degrees of success. The patient and family should be made aware of the sophisticated cover-up cosmetics that are now available. The use of broad-spectrum sunscreen lotions during the summer months minimizes the con- trast between normal and involved skin. For some patients, the application of topical corticosteroids alone or with brief natural sunlight exposure early in the course of the disease may induce repigmentation. Narrowband UUB is also an effective treatment. Varying combinations of topical or oral psoralens and ultraviolet A light (PUVA) are used in the treatment of vitiligo.
