A Case Study of Anisakiasis in the Palatine Tonsils.

Anisakidosis is a nematode infection caused by the ingestion of larvae-infected raw or undercooked fish. Although gastric anisakiasis is a common disease in Japan due to the popularity of eating raw and undercooked fish, reports of anisakiasis in the tonsils are extremely rare. A 68-year-old man presenting with clinical features of peritonsillitis was admitted for examination. The right peritonsillar region exhibited slight edematous swelling and rash, and a white foreign body was observed. This foreign body was removed, and pathological examination revealed Anisakis.
