Myiasis is a pathogenic condition found in live humans and animals caused by various species of dipteran larvae. A 23-years old man was transferred to intensive care unit of the neurology clinic at his vegetative state following an electrical shock. Two days after his admission, nurses observed a lot of small (5-7 mm) dirty white worms (maggots) crawling in his stool. They were immediately identified as maggots (larvae). Then, maggots were continued presenting in his stool two days more. In the meantime, for proper identification a few worms were preserved in formalin. They were examined for their gross morphological features, were dissected in order to examine finer details, and finally identified as maggots of S a rc o ph ag a spp. For absolute confirmation three living maggots were preserved in 70% alcohol, and then submitted to the laboratory for identification. Cephalopharyngeal skeleton and the posterior spiracles were characteristic of the thirdstage larvae of S a rc o ph aga haemorrhoidalis. The third instar maggot was identified as S a rc o ph aga haemorrhoidal i s, based on the taxonomic characteristics. In this report, a case of intestinal myiasis caused by Sarcophaga haemorrhoidalis is aimed to present by reviewing the literature
