Gasterophilus: A Rare Cause of Cutaneous Myiasis in the United States.

Abstract

Cutaneous myiasis is most commonly seen in travelers returning to the United States. There are rare reports of US-acquired human myiasis, with Cuterebra larvae being the most common causative organism. Gasterophilus, also known as the horse botfly, however, rarely infests human hosts and typically presents as cutaneous migratory myiasis, unlike this case. We report a cutaneous furuncular myiasis due to Gasterophilus larvae in the neck and cheek of a 4-year-old female after visiting a campground in northern New York.
