A 78-year-old man was referred to our hospital for a detailed examination of a pancreatic tumor that filled the main pancreatic duct (MPD). The histological diagnosis of the endoscopic biopsy specimen was neuroendocrine tumor (NET) G3. The patient subsequently underwent total pancreatectomy. The histological diagnosis of the surgical specimen was also NET G3. This is the first report of a NET that occupied the MPD and was diagnosed by a preoperative endoscopic biopsy through the papilla of Vater. This case is a good example of a histopathological diagnostic method for pancreatic tumors invading the entire MPD.
一名78岁男性因对占据主胰管（MPD）的胰腺肿瘤进行详细检查而转诊至我院。内镜活检标本的组织学诊断为神经内分泌肿瘤（NET）G3。该患者随后接受了全胰切除术。手术标本的组织学诊断同样为NET G3。这是首例通过术前经十二指肠乳头内镜活检诊断出占据主胰管的神经内分泌肿瘤的报告。该病例是胰腺肿瘤侵犯整个主胰管的组织病理学诊断方法的一个良好范例。
