Intestinal myiasis caused by fly larvae parasitic in gastrointestinal tract was rare reported in children. We reported an infant with bloody diarrhea caused by intestinal myiasis. A 1 year and 7 months old boy presented with the only symptom of bloody diarrhea of unknown origin. In the second week of onset, numerous moving worms were observed in the bloody stool after bowel preparation with polyethylene glycol for colonoscopy. The bloody diarrhea disappeared after 1 week of combined therapy with albendazole and metronidazole. On follow-up after 6 months, the patient remained well without bloody diarrhea. In conclusion, intestinal myiasis being a rare disease that is very challenging to diagnose, physicians should remember it when they receive cases of bloody diarrhea with non-specific symptoms without any apparent cause.
