Abstract
The patient was a 58-year-old man with an 8-month history of right lower abdominal pain. He was referred to the hospital with a suspicion of a peritoneal abscess due to chronic appendicitis. Preoperative examinations showed a rise of CA 19-9 level, so that colonoscopy was added. We identified hypertrophy of the opening of the appendix and exudation of mucus from it. Following a biopsy from the lumen of appendix, cancer of the appendix in stage III a was diagnosed. Ileocecal resection was thus performed.
Primary cancer of the appendix presents difficulty in preoperative diagnosis. We report this case with some bibliographical comments.
