The prevalence of Urticaria pigmentosa varies depending on the population studied. It is estimated to affect approximately 1 in 2,000 to 1 in 7,000 individuals worldwide. The condition is more commonly diagnosed in children, with the majority of cases appearing before the age of 2. However, it can also develop in adults.
Urticaria pigmentosa is caused by a mutation in the KIT gene, which leads to the abnormal growth and accumulation of mast cells in the skin. These mast cells release chemicals such as histamine, causing the characteristic symptoms of the condition, including itching, flushing, and the formation of hives or lesions.
While Urticaria pigmentosa is generally considered a benign condition, it can cause significant discomfort and impact the quality of life for affected individuals. Treatment options focus on managing symptoms and may include antihistamines, topical corticosteroids, and avoidance of triggers that can exacerbate symptoms.
It is important for individuals with suspected Urticaria pigmentosa to consult with a dermatologist for proper diagnosis and management of the condition.
