Dry rashes, such as eczema, ringworm, lichen planus, granuloma annulare, and psoriasis, can be caused by bacteria, fungi, chemicals, or allergies. Treatment options include over-the-counter or prescription medications, cortisone creams, antihistamines, and ultraviolet light therapy. A doctor can diagnose the type of rash and recommend a treatment plan.
Rashes, also known as dermatitis, usually appear as red, itchy bumps or scaly patches and can be caused by bacteria, fungi, contact with chemicals or allergies, or the rash develops due to an inherited condition. There are many different types of dry rashes, including eczema, ringworm, and lichen planus. Granuloma annulare and psoriasis are two other types of rashes. Dry rashes can usually be treated with over-the-counter or prescription medications. People should see a doctor, who can diagnose the type of rash the patient has and recommend a treatment plan.
Eczema is a skin rash characterized by itchy, red, scaly bumps that can cover small or large portions of the person’s skin. The rash most often appears on the back of the knees, hands, or inside the elbows of the person. Eczema usually gets worse during the cold, dry winter months, and sometimes crusty or pus-filled blisters form on the skin. Cortisone creams, antihistamines, and ultraviolet light therapy are common treatments for these dry rashes.
Ringworm is a fungus that affects the surface of the skin, usually the scalp, groin or feet. This type of dry rash is contagious, and a person can get the disease from animals. Ringworm can present as a red, ring-like patch of skin, but it also forms flaky or scaly inflamed patches of dry skin. Antifungal creams or capsules are taken to rid the skin of the fungus.
Linchen planus is a rash characterized by shiny, purple or red bumps that usually form on the inside of the wrists, inside the mouth or on the ankles. This type of rash can cause hair loss if it forms on the scalp. The bumps can develop on top of each other, causing a more serious rash to develop.
Granuloma annulare is a type of dry rash that is the result of a chronic condition that creates red bumps or a circular rash. The bumps are itchy and cosmetically unappealing. It usually goes away within a few weeks and most commonly affects women, young adults, and children.
Another type of dry rashes are rosea psoriasis rashes. This type of rash is hereditary and creates large, scaly patches of skin that can form anywhere on the body, though it’s most common on the elbows, back, and knees. The skin may be flaky and white where the scaly patches have formed, and the person usually develops a rash after a triggering event, such as a stressful event or an infection.
