Mixed Tumor of the Appendix: A Rare Tumor Association

Abstract

Malignant tumors of the appendix are rare. They are present in 0.1% to 0.5% of appendectomy specimens: confirmed upon histological analysis. Mixed tumors in the appendix are exceptional. We report a mixed mucinous cystadenoma with a moderately differentiated adenocarcinoma of the appendix in a 64-year-old patient presented to the emergency room with bowel obstruction syndrome.
