[Myiasis caused by Dermatoba hominis after an organized tours in Amazonia].

BACKGROUND: Human cutaneous myiasis is a common disease in endemic tropical zones. The incidence of imported cases follows the development of organized tours in the tropics. CASE REPORTS: We report 2 cases of Dermatobia hominis furonculoid myiasis in patients who took 2 different organized tours which both visited the same Amazonian site in Peru (Puerto Maldonado). DISCUSSION: In Latin American countries, D. hominis myiasis is transmitted by Diptera (generally mosquitos, rarely flies) who carry eggs laid by an adult fly to man. This phenomena is called "phoresia" and explains the preferential localization of lesions in exposed areas unlike African myiasis caused by Cordylobia anthropophaga which contaminates clothing soiled when drying.
