Chapter 12: Skin Problems Caused by the Environment

Bites and Stings: Papular Urticaria

What is it?

Papular urticaria is a name for the reaction pattern seen with multiple insect bites, but also can occur due to contact with caterpillars, carpet beetles, and mites for whom humans are not a usual host.

What does it look like?

Papular urticaria presents with widespread small 1-2mm individual erythematous pruritic papules, many of which might be excoriated.
