Abstract:

We report a case of appendicitis caused by amebiasis in a 45-year-old Japanese man. He presented to our hospital with bloody stools in June 1998. Sigmoidoscopy disclosed erosion, and a biopsy of the erosion showed colitis caused by Entamoeba histolytica infection. Four months later, he was admitted to our hospital with a small elastic mass and severe pain in the lower quadrant of the abdomen, which was diagnosed as acute appendicitis. He underwent appendectomy. Histopathological examination revealed numerous E. histolytica trophozoites, and we diagnosed acute appendicitis caused by E. histolytica. The patient has been free of symptoms, colonoscopy has revealed no erosion, and biopsy has revealed no E. histolytica for 12 months after the operation.
