Neuroendocrine carcinoma cases, more frequent in the GI tract, have rarely been reported in extrapulmonary areas. Neuroendocrine carcinoma of the bladder is one of the malignancies with a poor prognosis, which is expected to cause rapid metastases. In addition, neuroendocrine carcinoma of the bladder constitutes < 1% of all bladder carcinomas. In this study, we present two rare cases, a combined small cell neuroendocrine carcinoma-high-grade urothelial carcinoma and a large cell neuroendocrine carcinoma, diagnosed at Çanakkale Onsekiz Mart University, Research and Practice Hospital Pathology Clinic, between November 2016 and January 2017. KEYWORDS: Bladder, L cell neuroendocrine carcinoma, Pathological features, Small cell neuroendocrine carcinoma.
神经内分泌癌病例更常见于胃肠道，在肺外区域很少有报道。膀胱神经内分泌癌是预后不良的恶性肿瘤之一，预计会迅速转移。此外，膀胱神经内分泌癌占所有膀胱癌的<1%。在本研究中，我们报告了 2016 年 11 月至 2017 年 1 月在恰纳卡莱 18 马拉蒂亚大学研究与实践医院病理科诊断的两例罕见病例，即小细胞神经内分泌癌-高级尿路上皮癌和大细胞神经内分泌癌。关键词：膀胱、L 细胞神经内分泌癌、病理特征、小细胞神经内分泌癌。
