Abstract:
Primary endocrine neoplasms of the biliary tract are exceedingly rare. We report on a 60-year-old man with diarrhea, vomiting and gastroesophageal reflux disease, with a primary gastrinoma of the common hepatic duct. The tumor was positive for a variety of immunohistochemical markers. Postoperatively the patient's symptoms disappeared and in the follow-up the patient was symptom free. To our knowledge, this is the first case in the literature of a primary gastrinoma in the common hepatic duct. The fact that the common hepatic duct is not located within the gastrinoma triangle made the diagnosis difficult and the distinct localization made the surgical treatment demanding.
