Neuroendocrin Tumor of the Gallbladder: A Case Report

Abstract

Background: Neuroendocrine tumors (NETs) of the gallbladder are rare and account for less than 1% of all gallbladder tumors. These tumors are typically asymptomatic and are often discovered incidentally during imaging for other reasons. The majority of NETs of the gallbladder are non-functioning, meaning that they do not produce hormones or cause hormonal symptoms. Case Presentation: A 32-years old woman presented with a six-month history of non-specific abdominal pain without a remarkable prior history. Ultrasonographic examination of the abdomen revealed the gallbladder containing multiple stones, with wall thickening. A laparoscopic cholecystectomy was performed, and histopathological examination of the resected gallbladder confirmed the presence of a neuroendocrine tumor. Conclusion: This case report highlights the importance of considering neuroendocrine tumors as a differential diagnosis for gallbladder masses. The patient underwent a successful laparoscopic cholecystectomy and had a good outcome. Close follow-up is necessary to detect any recurrence as these tumors have a tendency to recur locally.
