Incidental synchronous appendicular neuroendocrine tumor in patient with right colonic adenocarcinoma

Abstract

Neuroendocrine tumor (NET) is the most common tumors of the appendix which is usually found incidentally. Synchronous neuroendocrine tumor of the appendix and colonic carcinoma has been reported in previous case reports. The actual incidence of these synchronous tumors need to be determined by reviewing these case reports and the need to include appendectomy as part of oncological colorectal operations.
