[Cutaneous myiasis caused by a double infestation with larvae of Dermatobia hominis and Cochliomyia hominivorax].

In a 51-year-old man who had visited Surinam, cutaneous myiasis was diagnosed, caused by simultaneous infestation with the larvae of two different species of flies: Dermatobia hominis and Cochliomyia hominivorax. On his right lower arm the man had two solitary, furuncle-like lesions with a central breathing hole. Two days after these holes had been occluded with vaseline, two white larvae of D. hominis emerged. On both ankles the man had large, undermined ulcers containing hundreds of creeping larvae about 2 cm in length with a salmon-like colour: C. hominivorax. The larvae were removed from the ulcers by hand and by rinsing with physiological saline, after which the wounds healed rapidly. Myiasis is seen in the Netherlands mostly in people returning from a holiday in myiasis-endemic areas.
