An 81 year-old woman suffering from anemia from May 2002 was diagnosed endoscopically with a huge polypoid cecal cancer tumor in August 2002. At surgery, the cecum was intact and the appendix had invaginated into the cecum. The tumor was preoperatively diagnosed as cecal cancer but proved to be invaginating appendical cancer, necessitating ileocecal resection with lymph node dissection. Histopathological examinations showed well differenciated adenocarcinoma with mucinous carcinoma of the vermiform appendix. We detail this rare case of primary carcinoma of the vermiform appendix invaginating into the cecum together with a discussion of the literature.
