An elderly male with long-standing Type 2 diabetes presented with a chronic wound over the right foot. On examination, a solitary punched-out plantar ulcer with hyperkeratotic margins measuring about 3 × 2 cm was noted [Figure 1a]. Floor of the ulcer showed yellowish slough containing grey coloured larvae. Polarised dermoscopy revealed multiple, mobile, greyish-white larvae exhibiting respiratory spiracles, pigmented tracheal tubes and circumferential brown dots [Figure 1b and Video 1]. The clinical and dermoscopic features established the diagnosis of wound myiasis. The larvae most probably belonged to the Calliphoridae family based on the morphological characters.
Wound myiasis refers to infestation of unattended wounds by the larvae of arthropod order Diptera. Dermoscopy assists not only in confirming the diagnosis by in vivo visualisation of larvae; it also helps in species identification and assists removal of the larvae not visible to the naked eyes.
