Abstract:
We report a case of necrosis caused by the use of prallethrin (mosquito repellent) on the skin in a 67-year-old diabetic female patient suffering from delusions of parasitosis. Cutaneous toxicity due to pyrethroids is less known or reported, despite well-documented pyrethroid poisoning involving the gastrointestinal, respiratory, cardiac, and nervous systems. Skin irritation has been described after acute accidental exposure but, as far as we know, no data have been published on the effects of pyrethroids when applied directly to the skin.
