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.
