Study of a primary gastrinoma in the common hepatic duct - A case report

Primary endocrine neoplasms of the biliary tract are exceedingly rare. We r eport on a 60-year-old man with diarrhea, vomiting and gastroesophageal ref lux disease, with a primary gastrinoma of the common hepatic duct. The tumo r was positive for a variety of immunohistochemical markers. Postoperativel y the patient's symptoms disappeared and in the follow-up the patient was s ymptom 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 h epatic duct is not located within the gastrinoma triangle made the diagnosi s difficult and the distinct localization made the surgical treatment deman ding.
