Introduction

My first duty is to thank Dr. David Schoetz for the invitation to edit this edition of Seminars in Colon and Rectal Surgery, I sincerely appreciate the opportunity. This edition will review most of the least common tumors challenging physicians treating tumors of the colon, rectum, and anus; we specifically avoid discussion of colon and rectal adenocarcinoma. Several of these tumors are extremely rare and their management is very challenging, with limited evidence for both surgical and non-surgical treatments.
