Endoscopic ultrasound‐guided fine‐needle aspiration (EUS‐FNA) allows a reliable and accurate diagnosis of neoplasms of the gallbladder and bile ducts. We report the cytopathologic findings of a case of large cell neuroendocrine carcinoma (LCNEC) of the gallbladder and extrahepatic bile ducts in a 67‐year‐old woman who presented with progressive abdominal pain and jaundice. EUS‐FNA of the mass involving the common bile duct and of a porta hepatis lymph node showed abundant cellularity with tumor… 
A large cell neuroendocrine carcinoma of the gall bladder: diagnosis with 18FDG-PET/CT-guided biliary cytology and treatment with combined chemotherapy achieved a long-term stable condition.
TLDR
Combination chemotherapy with cisplatin and docetaxel, the regimen used for non-small cell lung carcinomas, and probably large cell lung cancers, resulted in the disappearance of the lymph node metastases and a marked improvement in the performance status for ∼22 months.
Neuroendocrine carcinoma diagnosis from bile duct cytological specimens: A retrospective single‐center study
TLDR
Cytological examination of bile and/or bile duct brushing specimens can be useful for the diagnosis of small cell NEC, and its diagnosis by identifying characteristic cytological features may facilitate early detection and treatment.
Biliary tract large cell neuroendocrine carcinoma: current evidence
TLDR
The prognosis of hepatobiliary LCNEC remains poor with median survival of only 11 months from initial diagnosis, and studies focusing on high grade neuroendocrine carcinoma are needed to enhance the understanding of biology and therapeutics in this rare but aggressive cancer.
Large Cell Neuroendocrine Carcinoma of the Gallbladder: A Case Report and Literature Review
TLDR
The diagnosis of pure LCNEC without other histologic components was immunohistochemically confirmed after radical cholecystectomy and lymph node dissection in the hepatoduodenal ligament, and no evidence of recurrence or metastasis was observed after 6 months.
Imprint cytological feature of large cell neuroendocrine carcinoma of the gallbladder: a case report.
TLDR
Although performing a histological examination is important for making a final diagnosis, imprint cytology is powerful tool for differential diagnosis of LCNEC, especially in patients with carcinoma with poor differentiation.
Non-functioning neuroendocrine tumors of the common hepatic duct: a case report and literature review
TLDR
A case of an 18-year-old female, complaining from a dull epigastric pain related to a nodule compressing the common hepatic duct, showing a nodular tumor located in the common liver duct just above the insertion of the cystic duct with close contact with the pancreatic head distally is reported.
Gallbladder neuroendocrine carcinoma: An important differential diagnosis of gallbladder adenocarcinoma
TLDR
This case report highlights the importance of pathological diagnosis and the efficiency of endoscopic ultrasound‐guided fine‐needle aspiration in gallbladder neuroendocrine carcinomas and recommends attempted pathological diagnosis in unresectable cases.
Neuroendocrine tumors of the gallbladder
TLDR
An up-to-date review of the clinical features, diagnosis and treatment of NETs of the gallbladder, including GB-NEN, is presented to improve patient longevity.
The role of endoscopic ultrasound in the diagnosis of gallbladder diseases
Endoscopic ultrasound (EUS) has recently played an increasing role in the diagnosis of gallbladder diseases. This review aims to summarize the role of EUS in the diagnosis of gallbladder lesions. EUS

Endoscopic ultrasound guided fine‐needle aspiration diagnosis of duodenal high grade neuroendocrine carcinoma underlying a villous adenoma: Report of a case
TLDR
This case emphasizes the diagnostic value of EUS‐FNA sampling of the submucosal and intramural component of villous tumors of the gastrointestinal tract when mucosal forceps biopsies show only benign findings.
Composite large cell neuroendocrine carcinoma and adenocarcinoma of the common bile duct
TLDR
Findings in the first case of LCNEC combined with an adenocarcinoma component in the common bile duct are consistent with the theory that both of the carcinoma components originated from a common pluripotent stem cell.
Endoscopic ultrasound-guided fine-needle aspiration biopsy in the evaluation of bile duct strictures and gallbladder masses: a systematic review and meta-analysis
TLDR
EUS-FNA was an accurate and safe tool in the evaluation of patients with bile duct and gallbladder masses with a meta-analysis and high-quality prospective studies are still needed to be conducted.
Small cell carcinoma of the extrahepatic bile duct diagnosed with EUS-FNA and effectively treated with chemoradiation.
TLDR
The patient was treated with combined chemotherapy of cisplatin and CPT-11, which resulted in the disappearance of the tumor mass by image tests and radiation therapy, resulting in a marked decrease of serum neuron specific enolase levels and amelioration of jaundice.
Endoscopic ultrasound-guided fine-needle aspiration in the evaluation of gallbladder masses.
TLDR
In patients with obstructive jaundice and equivocal ultrasound or CT findings, evaluation of the gallbladder for the presence of a primary malignancy by EUS is useful and EUS-FNA can be performed safely and can make a definitive diagnosis.
High-grade neuroendocrine carcinomas of the gallbladder and bile duct: Report of four cases with pathological correlation.
TLDR
3 large-cell neuroendocrine carcinomas and a small-cell carcinoma arising from the biliary system are reported.
Large cell neuroendocrine carcinoma of the gallbladder: report of two cases.
TLDR
The recognition of this rare tumor type carrying important clinical implications in regard to the use of chemotherapeutic agents and supplemental treatments (for example, somatostatin analogs) is significant for two reasons.
Large cell neuroendocrine carcinoma of the gallbladder: long survival achieved by multimodal treatment
TLDR
The patient has survived for 69 months since the initial diagnosis and has shown no signs of recurrence at 35 months after the last γ-knife irradiation for brain metastases, suggesting that multimodal treatment including surgery, chemotherapy, and radiation therapy achieved a good response and led to long survival.
Combined Large Cell Neuroendocrine Carcinoma and Adenocarcinoma of the Gallbladder
TLDR
A 45-year-old male patient presented with right upper abdominal pain associated with anorexia, nausea, and passing of dark urine, a clinical picture of obstructive jaundice for 10 days, which confirmed the presence of a gallbladder mass with multiple liver nodules.
