A Case of Stump Appendicitis in which Preoperative Diagnosis was Difficult

Abstract

The patient was a 50-year-old man who was referred to our hospital with right lower abdominal pain. He had a history of undergoing appendectomy for acute appendicitis 30 years earlier. Abdominal CT showed the presence of a mass in the ascending colon and cecum with calcification. A preoperative diagnosis of inflammatory tumor was made as the patient gave a history of having mistakenly ingested a denture six months previously. Ileocecal resection was performed. Histological examination showed chronic inflammation of the stump of the appendix with no evidence of the denture.
