Carver College of Medicine, Iowa City, Iowa Urticaria (i.e., pruritic, raised wheals) and angioedema (i.e., deep mucocutaneous swelling) occur in up to 25 percent of the U.S. population. Vasoactive mediators released from mast cells and basophils produce the classic wheal and flare reaction. Diagnosis can be challenging, especially if symptoms are chronic or minimally responsive to therapy. A thorough medical history, physical examination, and methodical investigation are necessary to uncover diagnostic clues. Although serious medical illness can occur concurrently with chronic urticaria, acute urticaria generally is benign and self-limited. The mainstay of therapy for urticaria is avoidance of known triggering agents, judicious use of oral corticosteroids, and treatment with long-acting second-generation antihistamines, H A PDF version of this document is available.

Urticaria Pigmentosa I. Definition: Urticaria pigmentosa is an uncommon rash that usually affects the neck, arms, legs and trunk of children and young adults. The rash consists of reddish-brown spots that turn into hives when they are rubbed hard or scratched. Sometimes the spots will blister. II. Causes: The spots in urticaria pigmentosa contain a large number of mast cells (cells are the bodies building blocks). Mast cells are immune cells (cells that fight infection) that live in the skin. Mast cells make a substance called histamine. Histamine causes hives, itching, and flushing. We do not known why people with urticaria pigmentosa have abnormal collections of mast cells in the skin. III. Prognosis: Most children who develop urticaria pigmentosa before the age of five will have resolution of the condition by adolescence or early adulthood. When urticaria pigmentosa starts after the age of five, the abnormal collections of mast cells will sometimes involve the internal organs and the disease does not always go away. These patients need blood tests and other studies. IV.

Site map Search: Home Reactions Urticaria Urticaria refers to a group of disorders in which red patches and weals occur in the skin. The release of chemicals from mast cells in the skin causes small blood vessels to leak and results in tissue swelling. The weals can be a few millimetres or several centimetres in diameter, coloured white or red, often surrounded by a red flare, and frequently itchy. Each weal may last a few minutes or several hours, and may change shape. Weals may be round, or form rings, a map-like pattern or giant patches. The surface weals may be accompanied by deeper swelling of eyelids, lips, hands and elsewhere. The swelling is called angioedema . Angioedema may occur with or without urticarial weals (10%). Angioedema Urticaria Generalised urticaria Generalized urticaria (hives) is often classified according to how long it has been present. Acute urticaria is of recent onset (hours, days or a few weeks).

Urticaria (Hives) Urticaria is the medical name for hives. These are welts; pink swellings that come up on any part of the skin. They itch and each individual hive lasts a few hours before fading away, leaving no trace. New hives appear as old areas fade. They can be pea sized or join to cover broad areas of the body. While the itch can be intense, the skin is usually not scabbed or broken. In some people the hives burn or sting. Hives are very common with 10-20 percent of the population having at least one episode in their lifetime. Hives can sometimes occur in deeper tissues of the eyes, mouth, hands or genitals. These areas mat develop a swelling that is frightening in appearance, but usually goes away in less than 24 hours. This swelling is called angioedema. In many cases, a single attack of hives is due to an infection or virus and these go away within a few days to a few weeks. Some people get repeated attacks that occur as an allergic reaction to a variety of things (foods, most commonly nuts, chocolate, fish, tomatoes, eggs, fresh berries and milk, insect stings, and medications). In this case, they usually break out within a few hours of the exposure. Usually, the patients figure out the cause by themselves, and they never bother coming to a doctor. Certain people can develop recurrent hives from sunlight, cold, pressure, vibration or exercise. These are called the physical urticarias. If hives develop from scratching or firmly rubbing the skin it is called dermatographism. It is the most common of the physical urticarias and it affects about 5 percent of the population. It doesn't always itch. This condition sometimes also occurs along with other forms of hives.

Urticaria www.Studenthealth.co.uk Urticaria is often referred to as nettle rash or hives. The disorder causes wheals var word = "wheals" document.write('') in the skin. The weals can be a few millimetres or several centimetres diameter, coloured white or red, often surrounded by a red flare, and usually itchy. Each wheal may last a few minutes or several hours, and may change shape. Wheals may be round, or form rings, a map-like pattern, or giant patches. Involvement of the face may cause swelling of the eyelids and lips. The wheals and swellings occur because of the release of chemicals, such as histamine, into the tissues. This causes small blood vessels to leak fluid into the skin. There are various different types of urticaria, which can be classed as "acute", meaning it has only been present recently (hours, days or a few weeks), or "chronic", meaning it has persisted for several months or even years. Wheals may not be present all the time, often being more noticeable at certain times of day or when hot. Cause People often associate acute urticaria with an allergic reaction. Typically, medicines such as antibiotics, or food, including even tiny amounts of fish, eggs, nuts or chocolate, are responsible. It depends on previous exposure to the material, and the development of an immune reaction to it.

"Hives" and "welts" are red, itchy, and raised areas of the skin of varying shapes and sizes. Medically, hives are also known as urticaria. Hives are the result of histamine and other compounds that are released from cells called mast cells. Histamine causes serum to leak from the local blood vessels, which causes swelling in the skin. Hives can occur anywhere on the body, but are most commonly found on the trunk. Hives tend to erupt in clusters. Clusters of hives typically fade away and clear up within 2-48 hours as new clusters appear on other areas of the skin. Urticaria is a common skin condition that will affect one out of every five persons in the population. The cause of urticaria is often unknown. Fortunately, urticaria usually resolves by itself, and is rarely life-threatening. What are the categories of urticaria?
