Carcinoma of the extrahepatic biliary tract accounts for <2% of all cancers. Neuroendocrine tumor of the extrahepatic bile duct is very rare, and there are <200 cases reported since 1959. The preoperative diagnosis is infrequent (5.12%). The definite diagnosis relies on postoperative pathology which utilized immunohistochemistry study on many biomarkers to diagnose the histological subtypes of neuroendocrine neoplasms, such as chromogranin A, synaptophysin, and neuron-specific enolase. When the primary tumor has no metastases, radical removal of the lesion appears as curative treatment. The treatment of the carcinoid syndrome or other functioning syndrome is the first priority. We report a case of a 12-year-old Mexican woman with neuroendocrine tumor of the extrahepatic bile duct (common bile duct neuroendocrine tumor) seen in our hospital. Resection of the common bile duct, cholecystectomy, end to side Roux-en-y hepaticojejunostomy, and portal lymphadenectomy was performed. A review of the pertinent literature was performed. Given the rarity of the disease, treatment principles are based mainly on retrospective series and case reports. We present the eighth case in adolescence in the literature.
