It can also cause angioedema and systemic symptoms Solar urticaria is a rare form of chronic inducible urticaria (hives) in which the skin swells within minutes of exposure to natural sunlight or an artificial light source emitting ultraviolet radiation. The reaction may subside within a few minutes or it may persist for up to an hour or more where it can become very disabling Urticaria is also known as hives, weals or nettle rash. Solar urticaria is found worldwide, and whilst it can start at any age it appears to be those aged between 20 and 40 who are most affected. What causes solar urticaria?

A number of other treatments are available for difficult to control cases of acute and chronic urticaria. Extensive acute urticaria is sometimes treated in the emergency room with epinephrine. Chronic urticaria unresponsive to antihistamines can be treated with doxepin, leukotriene receptor antagonists, and immunosuppressants such as tacrolimus and cyclosporine Neutrophilic urticarial dermatosis (NUD) is a rare form of dermatosis. In clinical terms, it consists of a chronic or recurrent eruption comprising slightly elevated, pink to reddish plaques or macules. The elementary lesion lasts 24 to 48hours and resolves without leaving any residual pigmentation.

There is also an exteremely rare form called telangiectasia macularis eruptiva perstans. The signs, symptoms and severity of the condition vary by subtype Dermatographic urticaria (also known as dermatographism or skin writing) is marked by the appearance of weals or welts on the skin as a result of scratching or firm stroking of the skin

Those patients with chronic urticaria need evaluation. A skin biopsy is sometimes performed on hives lasting longer than 24 hours.

Urticaria is caused by the release of histamine and other chemicals from cells in the skin called mast cells. Urticaria is often thought of as an allergy but, in fact, it usually results from histamine release from mast cells due to other reasons. Allergens in food, or medicine may sometimes cause acute urticaria Urticaria may occur as a non-allergic phenomenon. These are classified as physical urticaria and are induced by scratching, pressure, cold, heat and sunlight. The most common physical urticaria is induced by rubbing or scratching and is called dermographism (skin writing)

Chronic hives (urticaria) are when hives occur most days for more than 6 weeks. They are less common than acute hives, with about 1 in 1000 people affected. They are more common in women than men (two-thirds of those with this condition are women). Symptoms are the same as in acute hives, but last longer Chronic spontaneous urticaria is defined as the occurrence of wheals and/or angioedema for a total duration of six weeks or more. Synonymous with chronic urticaria and chronic idiopathic urticaria, it can be a debilitating condition with significant detriment on a patient's quality of life

Overview. Urticaria (hives) are a very common eruption. They are both allergic and nonallergic causes. Hives are classified as acute and chronic. Hives lasting longer than 6 weeks are arbitrarily classified as chronic urticaria. Acute urticaria is often caused by exposure to medication or foods. The cause however in many cases is never determined Urticaria - also known as hives, weals, welts or nettle rash - is a raised, itchy rash that appears on the skin.

Drugs (2 days ago) Drug-induced urticaria is the term used when urticaria is caused by a drug, most often penicillin, a non-steroidal anti- inflammatory agent ( NSAID), or sulfamethoxasole in combination with trimethoprim (see Sulfa drugs and the skin) [1]. The drug may be ingested or applied to the skin. Acute drug-induced urticaria is the most frequently observed subtype in adults and children [1]. The estimated prevalence of chronic drug-induced urticaria is between 0.5 and 3% [1]. Chronic drug. Acute annular urticaria is a common and benign cutaneous hypersensitivity reaction seen in children that manifests with characteristic annular, arcuate, and polycyclic urticarial lesions in association with acral edema.

Urgent administration of adrenaline and medical assessment is required. See Anaphylaxis; Acute urticaria can be effectively treated with a non-sedating antihistamine. Urticaria pigmentosa is composed of persistent brown or red marks, made of collections of mast cells that swell and itch transiently when rubbed, similar to a hive.
