Furuncular myiasis from Dermatobia hominus: a case of human botfly infestation.
BACKGROUND
Travelers to tropical regions are at risk for a myriad of exotic illnesses. Malaria and dengue are diagnoses that are associated with insect bites, in particular, mosquito bites, acquired while traveling in foreign, tropical countries. Infestation with Dermatobia hominus, the human botfly, endemic to South and Central America, is usually transferred via a mosquito vector. The human botfly should be considered in patients who have traveled to these endemic regions and present with a mosquito bite history and non-healing skin lesions.


OBJECTIVE
We present this case to increase awareness among emergency physicians regarding furuncular myiasis from the human botfly.


METHODS
A 39-year-old pregnant woman presented to the Emergency Department (ED) with an intensely pruritic lesion to the right calf and mild systemic symptoms 6 weeks after travel to Belize. The lesion she thought was a mosquito bite had persisted despite escalating treatment modalities and had been incorrectly diagnosed by multiple physicians.


CONCLUSIONS
Parasitic disease is not always a systemic process. Botfly infestation presents as local boil-like lesions that are irritating and uncomfortable. Once correctly identified, it can be easily treated in the ED.
