Goblet cell carcinoid of the appendix is a rare neoplasm with histological features of both neuroendocrine and adenocarcinomas. The combination of its aggressive behavior, infrequent occurrence, and variable clinical presentation convolutes the management of this tumor. We report the case of a 75-year-old female presenting with acute appendicitis. A laparoscopic appendectomy was performed. The pathology report showed goblet cell carcinoid at the base of the appendix with involvement of the proximal surgical margins. At her postoperative visit, the patient’s pathology report and options for management were reviewed, and the patient agreed to proceed with a right hemicolectomy 8-10 weeks after her appendectomy.
