Amoebiasis Presenting as Acute Appendicitis.

We report a case of amoebic appendicitis without colitis symptoms. Acute appendicitis is commonly encountered by gastroenterologists in their daily practice. The number of cases of amoebiasis increases annually in Japan, and is thought to be associated with an increase in sexually transmitted disease or travel to endemic areas. However, acute amoebic appendicitis is rare and the prognosis is very poor compared to nonamoebic appendicitis. In our case, appendectomy was performed immediately after onset, and the patient was discharged without complications. It is difficult to differentiate between amoebic and nonamoebic appendicitis preoperatively, and the possibility of amoebic appendicitis should be kept in mind.
