How Do You Spell URTICARIA PERSTANS?

1. Urticaria perstans is a medical condition characterized by a chronic and persistent form of urticaria, which is commonly known as hives. Urticaria refers to a skin disorder that results in the sudden appearance of itchy, raised, and often red or pink welts on the surface of the skin.

   Urticaria perstans, specifically, is a subtype of urticaria that manifests as small, round or oval-shaped hives that develop gradually and persist for longer periods of time, often for more than 24 hours. These welts typically vary in size and may be present all over the body, although they tend to be concentrated on the trunk, arms, and legs.

   The condition is thought to be caused by the activation of certain immune cells called mast cells, which release histamine and other chemicals that lead to the characteristic rash and itching. The exact underlying cause of urticaria perstans is not yet fully understood, but it is believed to be related to an abnormal immune response triggered by various factors such as allergens, infections, medications, stress, or autoimmune processes.

   Urticaria perstans is typically diagnosed based on the appearance of the hives, their chronic and persistent nature, and the absence of other identifiable causes. Treatment options often include the use of antihistamines to alleviate itching and other symptoms. In some cases, additional medications such as corticosteroids or immunosuppressants may be prescribed to achieve better control of the condition.

   Overall, urticaria perstans is a chronic skin disorder characterized by long-lasting wheals or hives that require proper medical attention and management to mitigate symptoms and improve quality of life.
