At the base of the tail, in the lumbar region, a nodular lesion approximately 0.5 cm in diameter was observed, containing a central orifice (Figure 1A). Digital compression was performed, which first expelled a dead larva of D. hominis from the tail, and a second larva, still alive, from the base of the tail (Figure 1B). The use of topical isoxazolin was recommended, along with sanitizing lesions with 1% chlorhexidine until total healing (Figure 1C and 1D).
