- Ascaris lumbricoides infection distributed widely in tropical and subtropical areas, especially in the developing countries and affects more than one billion of people. Ascariasis commonly has higher infection rates compared to other parasite species and because of poor sanitation the parasite can be seen in 100 % of the population. A. lumbricoides depending on the provocation by anesthetic agents or intestines becomes hostile, such as with inflammation and obstruction, may cause migration and varies complications such as coming up to the mouth or blocking some ducts. We report a case of pharyngeal ascariasis with worm migration, in a 67-year-old woman was referred with complaints of nausea and dysphagia.
