[Update on Dermatobia hominis: South American furuncular myiasis].
Furuncular myiasis is an infestation of the skin caused by Dermatobia hominis larvae known as "ver macaque" in French Guyana, "berne" in Brazil, "torsalo" in Colombia, or "human botfly" in English-language literature. It has identical features in man and domestic mammals. The primary lesion consists of a boil-like inflammatory papule with a central punctum exuding a serosanguinous discharge. The respiratory sinus of the D. hominis larvae may be visible through the punctum. Myiasis secondary to D. hominis accounts for 10% of imported tropical dermatosis observed in Paris. Diagnosis of furuncular myiasis should be considered in any patient with a history of travel or residence in an endemic area. Treatment depends mainly on mechanical removal that may be facilitated by injection of lidocaine into the lesion or prior application of a 1% solution of ivermectin.
