Inverted appendix in a patient with colon cancer: a case report and long-term follow-up.

Appendiceal inversion is a rare entity that can potentially mimic serious pathology and provide diagnostic uncertainty. They are mostly diagnosed intraoperatively or during endoscopies and scans for other reasons. We report a case of an asymptomatic patient treated for colon cancer without previous history of appendectomy. We provide long-term follow-up and aim to review the relevant literature.
