Enterobius vermicularis is one of the most common intestinal nematode worldwide. Enterobius rarely causes a symptomatic disease. We report here an unusual case of a 60-year old man who came with a polypoidal growth in the anal canal increasing in size for past 20 years. He had pain and intense itching over the mass. The differential diagnosis of squamous papilloma, fibroma and foreign body granuloma were considered. The mass lesion was excised surgically and sent to the pathology laboratory. The mass turned out to be an "E. vermicularis worm granuloma" by histopathologic examination. Thus, timely reporting and surgical resection of such lesion is necessary to prevent further complications. This case is reported here for the unusual presentation of pinworm as a pseudoneoplasm in the anal canal. Incidence of these cases reflected the poor personal hygiene and improper disposal of human excreta in the rural areas. We insist that health education is the only way to control the spread of helminthic infections that causes a heavy disease burden to our country.
