For few ANENs located at the base, or small tumors (\u22642 cm) infiltrating the submucosa, the muscularis, the subserosa layer or the mesoappendix, right hemicolectomy is recommended. However, no guidelines have been established concerning patients with appendiceal perforation in case of ANENs.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Although rare, ANETs should be considered in the differential diagnosis of acute appendicitis.
