papular urticaria

This is a peculiar condition affecting mainly of children, in which the sites of old arthropod bites react almost as if they had been bitten again.

It is a disease of the warmer months, when biting bugs are active. It is triggered by bites from any of a number of arthropods - usually fleas, chiggers or mosquitoes, but also mites, bedbugs, gnats, and animal lice. The lesions or sores usually start as small raised patches of skin similar to urticaria (hives), that mature into firm reddish-brown bumps. The key is that a few bites cause a general eruption of all the old bite sites. This is know in dermatology as an "id reaction."

Treatment would be avoidance of new bites, with antihistamines orally and cortisone cream topically for flareups.
