There are many types of skin rashes, occurring for a variety of reasons. They can range from irritating to alarming. In some cases, a rash can become so painful it is debilitating.
This is a chronic skin disease, caused by a dysfunction of the immune system. Skin cells develop too quickly, and they are not shed. Instead, they build up on the surface of the skin, causing a rash. The exact cause of psoriasis is unknown, though it is believed to be a genetic condition triggered by factors such as stress. It is not contagious.
There are several types of psoriasis:
- Plaque – White or silver scaly patches
- Guttate – Small, red spots
- Pustular – Red, swollen, blisters filled with pus
- Inverse – Red, raw-looking, smooth patches
- Erythrodermic – Looks like a burn over most of the individual’s body with intense pain and itching. This condition can be life threatening, and the person should be taken to a hospital immediately.
: Also known as atopic dermatitis, this is a common skin condition in children, especially infants. It usually begins in the creases of the knees or elbows, though it can also occur in areas like the ankles, wrists, or neck. It begins as scaly, itchy patches. Without treatment, skin can become thick, leathery, bumpy, and perpetually itchy.
: About half of all affected children “outgrow” the condition, though they are likely to have sensitive, dry skin. For others, it continues into adulthood, with slightly different symptoms. Although rare, an individual who never had eczema in childhood can develop it as an adult. Eczema looks more scaly on adults than it does on children. In addition to the knees and elbows, it is often visible on the neck and face, especially around the eyes. It can completely cover a person’s body.
Dermatologists treat thousands of different skin conditions, many of which are rashes. A few of the most common include:
- Pityriasis rosea (Christmas tree rash) – A scaly rash, usually appearing on the back. It may form an outline resembling a Christmas tree.
- Contact dermatitis – An allergic reaction to a substance contacting the skin. It can be caused by virtually anything, including fabric, metal, cosmetics, and household cleaners.
- Drug rash – An external allergic reaction to a prescription or over-the-counter medication.
- Miliaria (heat rash) – Small bumps caused by restricted flow of sweat in hot conditions.
- Intertrigo – Inflammation of the skin caused by abrasion and moisture in areas where the skin touches, such as the groin, underarm, and abdomen.
- Herpes zoster (shingles) – A painful rash occurring in individuals who were infected with chickenpox in the past.
