A case report of pancreatic neuroendocrine carcinoma diagnosed by EUS-FNA

Abstract

We report a case of pancreatic neuroendocrine carcinoma diagnosed by using EUS-FNA. The patient was a 73 year-old man with a pancreatic body tumor. There was no elevation of CEA and CA19-9. Contrast enhanced CT images showed a pancreatic tumor as a hypovascular lesion of 30mm in diameter with main pancreatic duct dilation. The border of tumor was clear and irregular. The tumor was proximal to the portal vein, common hepatic artery, and gastroduodenal artery. Multiple liver tumors were detected in DWI-MRI. The pancreatic mass was detected as a low echoic lesion whose border was clear and irregular by EUS. We performed EUS-FNA with 22G needle, and the sample led to the pathological diagnosis of small cell neuroendocrine carcinoma. After diagnosis, he received chemotherapy with irinotecan and cisplatin. He died 6 months later due to cancer progression.
