Papular urticaria is a common skin condition which may affect any area of the body, though it typically appears in areas which are not covered by clothing such as the legs, face and/or forearms. The condition usually consists of small bumps which are red in color and accompanied by severe itching. In some cases, lesions may develop blisters at their center which are large and filled with fluid. Scratching due to itching may cause lesions to become infected, which can lead to pain and discharge. Newly developed lesions may also cause resolved lesions to come back, and lesions are likely to scar.

Papular urticaria occurs as a reaction to insect bites, typically fleas or mites, though other bites may cause the condition. Typically, affected persons eventually become resistant to the reaction, which lessens as time passes. The condition typically clears in a short period of time, up to a few weeks.
