A rare cause of dysphagia: pharyngeal ascariasis

Abstract

Ascaris lumbricoides infection distributed widely in tropical and subtropical areas, especially in the developing countries and affects more than one billion of people.

We report a case of pharyngeal ascariasis with worm migration, in a 67-year-old woman was referred with complaints of nausea and dysphagia.
