Incidental appendicular neoplasms

Abstract

Appendicular neoplasms present in up to 50% of cases as an episode of acute appendicitis. There are demographic, clinical and radiological characteristics that increase the chances of an underlying appendicular tumor; however, in most cases are the intraoperative findings that alert the surgeon. Although the histological type determines the radical nature of the surgical management of these patients, some macroscopic characteristics can guide specific pathologies and appropriate behavior. In general, the objectives of initial surgical management are met with a limited resection of the cecal appendix, associated with mucin cytology and biopsy of peritoneal implants if present, reserving extended resections such as oncological right hemicolectomy for patients with extensive compromise of the base or appendicular mesentery when neuroendocrine neoplasms or adenocarcinoma of the cecal appendix are suspected.
