case_images: View of the cutaneous cavitary defect in the zygomatic region. Larvae can be seen embedded in the posterior wall of the cavity (arrows). In the inset, the image of a partially extruded larva at the bottom of the lesion has been zoomed in. The posterior spiracles can be clearly discerned.

case_images: A 5x5 cm cavitated lesion with necrotic margins surrounded by edematous hyperemic skin was observed in the right zygomatic-malar region with necrotic margins with foul-smelling purulent discharge and apparent bone involvement (Figure 1).
case_images: Larva of Cochliomyia hominivorax being removed from the lesion with hemostatic forceps (left panel). Some of its taxonomic features can be identified: (a) the posterior spiracles, (b) the anal tubercles, and, in particular, (c) the pigmented tracheal trunks, which are the hallmark of this larval species. For comparison, (right panel) an image of a C. hominivorax larva is shown. Adapted from Paez-Diaz Ruth, Villa-Arteta Luisa C.

case_images: Surgical debridement was performed with removal of all larvae, whose macroscopic taxonomic characteristics matched those of Cochliomyia hominivorax (Figure 2).
