Abstract
A case of appendicitis caused by anisakiasis was experienced. A 16-year-old woman was admitted to our hospital because of acute appendicitis. She had eaten fresh “Sushi” 5 days before admission. Appendectomy was performed and anisakiasis of the appendix was revealed. Anisakiasis is commonly found in the stomach (92.7%), and occurs in the intestine in a frequency as low as 4.4%. In particular, there has been no report on anisakiasis of appendix in Japan up to now. This case is thought very rare.
