Myiasis with Dermatobia hominis in a Traveler Returning from Costa Rica: Review of 33 Cases Imported from South America to Japan

Abstract

We experienced a case of Dermatobia hominis infestation from South America. Here we discuss imported cases of D. hominis in Japan with literature.

A case of cutaneous myiasis due to Dermatobia hominis in Japan

“…5 As in our case, in two other cases 9,11 the larva was found unexpectedly after incision of the lesion and was removed. Interestingly, there were cases whose larvae were successfully made to emerge by means other than incision without reaching the correct diagnosis: a larva appeared when the lesion was pushed (by the doctors in two cases, 12,13 and by the patients in two cases 8,14 ), and in 5 cases 15-19 a larva appeared from the pore of the lesion, probably because its air supply was cut off because an ointment had been applied. However, it should be noted that there were 11 patients 12,14,16,17,[20][21][22][23][24][25][26] (about one third of all cases) who were given unnecessary resection of the lesions; 4 of these cases involved resection of the nodules even after a larva had appeared.…”

Cutaneous Myiasis from Panama, South America: Case Report and Review

A tetanus booster should also be recommended, especially in the presence of an open pore or wound.…”
