Introduction. Myiasis is an infestation of the tissues and organs of living vertebrates by fly larva that feed on the host’s necrotic or living tissue; it is a well-recognized complication of neglected wounds. Case. A 17-year-old boy presented to a pediatric outpatient department for delayed wound healing of his left toe. Three months prior, he had undergone left great toenail wedge excision for an ingrown toenail; following the operation, he ignored wound care due to pain while dressing the wound. At presentation, the lateral edge of his left toe was hyperemic and swollen without pain or purulent material. The larvae were observed on the lesion’s necrotic tissues. The orthopedist debrided the necrotic tissues, removed the larvae, and an antibiotic was administered to treat a secondary bacterial infection. The wound was kept clean and dry. Microorganisms did not grow in the debrided necrotic tissue culture, and antibiotic treatment was completed in 14 days. With proper wound care, closure was achieved without reoccurrence or complications. Conclusion. Early diagnosis is important to initiate prompt treatment for myiasis. When open wound healing is delayed despite the appropriate antibiotic treatment, especially in tropical or subtropical regions, myiasis should be suspected.
