A case of cutaneous myiasis due to Dermatobia hominis : twelfth case in Japan

Abstract

The twelfth case of Dermatobia hominis myiasis imported into Japan was reported. Two weeks after a trip to Brazil, a 21-year-old man visited the dermatology clinic with indurated frunculoid lesion on the right upper arm. Oral antibiotic therapy was ineffective. The eruption started with a mosquito bite in the tropical forest and became an inflammed nodule with a central opening from which serosanguinous fluid oozed. He noted a little white body protruding in and out of the nodule and succeeded in taking out this worm from the lesion by himself. The worm was identified as Dermatobia hominis. The clinical features of 12 reported cases of Dermatobia hominis myiasis in Japan were reviewed.
