Case #423 - July 2016

A six-year-old boy from Washington, D.C. presented with a non-migratory furuncle on his scalp several weeks after returning from a trip to Belize (Figures A and B). A small incision was made and a worm-like organism (Figure C) was removed. The case was diagnosed as furuncular myiasis and the specimen was sent to the CDC-DPDx for identification. Figure D shows a close-up of the posterior spiracles. What is your identification? Based on what criteria?
