Abstract
|
|
|
|
A 22-year-old Korean woman visited our outpatient department with complaints of discomfort and pain on the left part of her throat, occurring 3 days after eating raw fish with chopped fish bone. Laryngeal endoscopy revealed a slow-moving worm, about 5 mm in length, which was found attached to the surface of the left aryepiglottic fold. The fluke was removed by forceps, under local anesthesia with 8% lidocaine spray. The worm was identified to be Clinostomum complanatum (C. complanatum). C. complanatum infection in human is rare and known to occur after eating raw fish, a secondary intermediate host. In humans, metacercariae is known to enter the stomach and then migrate to the throat through the esophagus, causing laryngitis. The only treatment method for this parasite infection is a mechanical removal.
