BACKGROUD
Primary pancreatic paraganglioma is an extremely rare extra-adrenal paraganglioma.
CASE PRESENTATION
We report a case of primary pancreatic paraganglioma undergoing middle segment pancreatectomy in a 42-year-old woman. Histological examination showed that the tumor was composed of well-defined nests of cuboidal cells separated by vascular fibrous septa, forming the classic Zellballen pattern. The chief cells showed positive staining to neuron-specific enolase, chromogranin A, synaptophysin, and the chief cells were surrounded by S-100 protein-positive sustentacular cells. The patient has remained tumor free for 12 months after surgery. A brief discussion about the histopathological features, clinical behavior, and treatment of primary pancreatic paraganglioma, and review of the relevant literature is presented.
CONCLUSIONS
Primary pancreatic paraganglioma is a rare clinical entity, its diagnosis mainly depends on histopathological and immunohistochemical examinations. Complete surgical resection is the first choice of treatment and close postoperative follow-up is necessnary.
背景
原发性胰腺副神经节瘤是一种极其罕见的肾上腺外副神经节瘤。
病例报告
我们报告一例42岁女性原发性胰腺副神经节瘤行胰中段切除术的病例。组织学检查显示，肿瘤由界限清楚的立方形细胞巢组成，被血管纤维间隔分隔，形成典型的Zellballen模式。主细胞对神经元特异性烯醇化酶、嗜铬粒蛋白A、突触素呈阳性染色，主细胞被S-100蛋白阳性的支持细胞包绕。患者术后12个月无肿瘤复发。本文对原发性胰腺副神经节瘤的组织病理学特征、临床行为及治疗进行了简要讨论，并复习了相关文献。
结论
原发性胰腺副神经节瘤是一种罕见的临床实体，其诊断主要依靠组织病理学和免疫组化检查。完整的手术切除是首选治疗方法，术后密切随访是必要的。
