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%). Urticaria Chronic wealing Giant urticaria Angioedema Acute 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) I. Definition: Hives are itching red welts or small bumps that last for 15 minutes to several hours. They usually appear suddenly and leave no trace when they disappear. Crops of hives may appear several times a day, they may even last for weeks, sometimes longer. Hives are harmless except when they cause throat swelling; this is rare but requires immediate treatment. II. Causes: Hives can be caused by something taken internally, most often a medicine such as penicillin or aspirin. Sometimes foods cause hives; shellfish and strawberries are well-known examples. Hives are also sometimes caused by infection. Most of the time, we do not find the cause. III. Treatment: When treating hives, we try to find their cause. Medicine is prescribed to control the rash and itching. Hives are usually controlled with antihistamines. (Caution: antihistamines may cause drowsiness; if you feel sleepy, don't drive. Also do not drink alcohol.) Injections of epinephrine (Adrenalin) may be used for treating severe hives. Sometimes epinephrine-like medicines taken by mouth are used in combination with antihistamines.

"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?

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.

Their shapes vary, but they all have a clear border. They may occur throughout the body or may be restricted to the face, neck or limbs. They may arise one after another and recur frequently. After recovery there will be no trace remaining. 2. There is significant itching and a burning sensation. 3. Dermatological test is positive. The wheal may be caused by mechanical stimulation. 4.

If you feel that you have a skin problem, please see your doctor. Urticaria is a common skin disorder that is characterized by the spontaneous development of swollen pink or red itching areas called "hives", "whelps", or "wheels". These are produced by the leakage of a liquid portion of the blood through the walls of tiny blood vessels into the skin or mucous membranes of the body. Urticaria usually comes on abruptly, with large numbers of "hives" in repetitive crops. A "hive" can be a few inches to several inches in size and when individual "hives" join together they can even cover an entire body area. An individual "hive", from a particular crop, will usually disappear after a few minutes to several hours without leaving any permanent changes in the skin. Typically, most individuals, have a single attack of urticaria that lasts only briefly - for several days. This is referred to as ACUTE URTICARIA. Unfortunately, some cases of urticaria may also persist and "come and go" with attacks being intermittent or continual for years. When urticaria lasts more than three months, we refer to that type as CHRONIC URTICARIA.
