A case of filariasis reported from southern iran

A 56 year-old man with recurrent gastrointestinal bleeding is reported. The patient had constant crampy pain in his epigastrium, right upper quadrant and periumbilical area. Upper-gastrointestinal endoscopy was normal. Colonoscopy showed a soft-tissue mucosal lesion in the rectum which was determined to be a worm that extended into the lumen of the rectum with no bleeding. The pathology was microfilaria in the rectal glands. Filariasis should be taken into consideration in the differential diagnosis of recurrent gastrointestinal bleeding conditions in our area.
