Tropical rat mite dermatitis. Report of six cases and review of mite infestations.
Six cases of tropical rat mite (Ornithonyssus bacoti) dermatitis are presented. The patients experienced papular urticaria, and mites were found on and identified in several of the patients. The presence of rodents in or around the home was confirmed in most cases. The role of other parasitic mites found on bats, birds, and snakes is reviewed. The importance of obtaining a history of rodent activity or exposure to other animals is emphasized when considering the cause of arthropod bites.
