We report a case of furuncular myiasis complicated by Staphylococcus aureus infection and b-hemolytic streptococcal cellulitis. The Dermatobia hominis larva that caused this lesion could not be extracted using standard methods, including suffocation and application of lateral pressure, and surgery was contraindicated because of cellulitis. The botfly maggot was completely and rapidly extracted with an inexpensive, disposable, commercial venom extractor. Myiasis constitutes an invasion of

There are several species of dipteran flies whose maggots can parasitize the skin, vagina, urinary tract, gastrointestinal tract, nasopharynx, sinuses, eyes, and auditory canals of humans [1, 2] . However, the most common type of myiasis observed in returning travelers is furuncular myiasis caused by Cordylobia anthropophaga (tumbu fly) or Dermatobia hominis (human botfly). The range of the tumbu fly is restricted to sub-Saharan Africa, whereas the human botfly is commonly found in Mexico and throughout much of Latin America [3] . Furuncular myiasis commonly presents as a small, raised, red, bitelike lesion that evolves into an enlarging, pruritic, erythematous, tender nodule from which a sensation of movement and lancinating pain can be felt [3] [4] [5] [6] . Most patients complain of a serous discharge that issues through a central punctum either spontaneously or with application of lateral pressure. It is of no surprise that most infested individuals, who are uncomfortable about waiting the required 8-12 weeks for the larvae to mature and exit on their own, request that the larvae be extracted at the time of diagnosis.
