Both appendiceal diverticulum and appendiceal carcinoma are extremely rare. We encountered a case of appendiceal carcinoma with appendiceal diverticulum. This case is described in this paper with a review of the literature. A 67-year-old woman presented to our hospital with right lower abdominal pain. Appendectomy was perfomed under the diagnosis of acute appendicitis. A moderate amount of pus-like fluid was observed in the peritoneal cavity. The excised appendix possessed two diverticula, one of which was perforated. The diveriticula were demonstrated histlogically to be pseudo-diverticula. The perforated diverticulum showed massive neutrophilic infiltration. A signet-ring cell carcinoma extending to the subserosa was found at the base of the appendix. Therefore an ileocecal resection with lymph node dissection was perfomed. No residual tumor or lymph nodes metastasis were recognized. Appendiceal carcinoma with appendiceal diverticulum is extremely rare, and only 3 cases, including ours, have been reported in the Japanese literature.
