An Unexpected Guest: A Case of Cutaneous Furuncular Myiasis: The 2013 PEMpix Photo Competition Winner.

Dermatobia hominis, also known as the botfly, is a parasitic infestation commonly found in Central and South America. In humans, this usually presents as cutaneous furuncular myiasis, after the larvae become embedded in the skin. This produces a local inflammatory reaction, which may mimic cellulitis; however, definitive treatment requires removal of the botfly larvae. This infestation is uncommon in the United States but should remain high on the differential diagnosis of returning travelers presenting with cutaneous lesions, as seen in the reported case of a teenager after return from Central America.
