We recently experienced a case of intestinal myiasis caused by maggots of fly, Sarcophagidae. A 61-year-old Japanese man presented in August 2015 with a 2-day his-tory of diarrhea and white maggots in his stool. Two days before his presentation, he took Chinese noodles and lettuce. At his presentation, we observed a number of discharged insect bodies in his stool. The insect bodies were identified as the larvae of the 3rd instar flesh fly Sarcophagidae based on macroscopic and microscopic examinations. We finally diagnosed as intestinal myiasis due to the fact that the patient had the insect bodies mixed in his diet, lettuce. A few days after the treatment with antibiotics, his symptoms disappeared. Accurate diagnosis of intestinal myiasis in developed countries is necessary to avoid ineffective treatment.
