Gastrointestinal neuroendocrine tumors, although relatively rare, are one of the most common appendiceal neoplasms. Patient symptoms can range from asymptomatic to acute appendicitis, and these tumors are often diagnosed after histopathological evaluation. This case series describes five separate cases of appendiceal neuroendocrine tumors diagnosed by histopathological review following incidental appendectomy during benign gynecologic laparoscopic surgeries at a single multispecialty group. Each case had a preoperative diagnosis of chronic pelvic pain. Intraoperatively, the appendix appeared scarred, adhered, or nodular. Two patients required a right laparoscopic hemicolectomy for the management of the appendiceal neuroendocrine tumor. As a result of these findings, it is recommended that the appendix be routinely evaluated during gynecologic surgeries and, if abnormal in appearance, appendectomy should be performed. Additionally, laparoscopic gynecologic surgeons should receive appendectomy training to aid with the early diagnosis and treatment of appendiceal neuroendocrine tumors.
