A Case with Mucinous Cystadenocarcinoma of the Remnant Appendix Curatively Resected Following 38 Months after Being Discovered

Abstract

An 87-year-old-woman with a history of appendectomy visited our hospital due to scrutiny of anemia. We suspected the mucin-producing tumor, but she refused surgery. After, she was admitted to our hospital because of frequent abdominal pain at right lower. Because she wished for surgery, we performed ileocecal resection following 38 months after being discovered. Histopathologically, the tumor was diagnosed as mucinous cystadenocarcinoma, the colonic mucosa had no tumor. Immunohistological examination were also positive for all of CK7, CK20, CDX-2. Finally, we diagnosed the tumor as mucinous cystadenocarcinoma of the remnant appendix after appendectomy.
