Papular urticaria

Full Definition

Papular urticaria is a hypersensitivity reaction to arthropod bites, most commonly from fleas, mosquitoes, or other insects. It typically affects children aged 2-7 years and presents as clusters of intensely pruritic, urticarial papules often with a central punctum. Lesions may be grouped in areas of exposed skin and can persist for weeks. The condition tends to resolve as children develop tolerance to insect antigens.
