Goblet Cell Carcinoid (GCC) of the Appendix presenting as a Small Bowel Obstruction

Abstract

A 68 year old male presented to our Emergency Department with a one-day history of right sided abdominal pain, distention and vomiting on a background of no previous abdominal surgery. Abdominal CT demonstrated a high grade, closed loop small bowel obstruction involving the terminal segment of the ileum. Also of significance was alow-density appendiceal nodule. A subsequent laparoscopy revealed the tip of the appendix adherent to the mesosigmoid colon, forming a tight band and consequent mechanical bowel obstruction. Furthermore, the meso-appendix was embedded with crystal deposits and extruding mucin. The decision was made to convert to laparotomy and perform a caecectomy. Immunohistochemistry demonstrated reactivity to synaptophysin, chromogranin A and CD56, confirming the diagnosis of Goblet Cell Carcinoid. A staging CT after this initial surgery revealed no metastasis. After discussion at our oncology MDT, the patient went on to receive a completion right hemicolectomy which revealed no further malignancy on histology. The patient otherwise progressed well, and made a good post-operative recovery.
