The ampullary adenoma is also a rare neoplasm and has the potential to develop an adenocarcinoma. Their coexistence has been rarely reported in the literature. We herein describe an unusual case of a small cell neuroendocrine carcinoma associated with a villous adenoma in the ampulla of Vater with emphasis on computed tomography (CT) and histopathological findings. We also discuss their clinical, histopathological and radiological features as well as possible histogenesis.展开更多
目的:探讨宫颈小细胞神经内分泌癌(small cell neuroendocrine carcinoma of the cervix,SCNCC)的临床病理和免疫表型。方法:复习4例SCNCC的临床病理资料,并将其组织学特征、免疫表型和预后与宫颈鳞癌进行比较。结果:SCNCC的发病年龄平...目的:探讨宫颈小细胞神经内分泌癌(small cell neuroendocrine carcinoma of the cervix,SCNCC)的临床病理和免疫表型。方法:复习4例SCNCC的临床病理资料,并将其组织学特征、免疫表型和预后与宫颈鳞癌进行比较。结果:SCNCC的发病年龄平均38.5岁,多表现为接触性出血或阴道不规则流血、排液。组织学特征为肿瘤细胞小而圆,胞质少,核染色质深染,核仁不明显,分裂象多见,可见坏死,肿瘤细胞呈片状浸润。免疫表型显示4例均表达至少一种神经内分泌标志。4例SCNCC的发病年龄低于宫颈鳞癌,淋巴结转移率高于宫颈鳞癌,近期随访结果显示预后较宫颈鳞癌差。结论:宫颈小细胞神经内分泌癌是一种少见的高度恶性肿瘤,具有独特的病理形态特征,预后较差。免疫组化染色有助于确诊。展开更多
小细胞癌在临床上分为很多种类型,其中以肺癌最为常见,恶性度比较高,预后较差。在妇产科中,宫颈小细胞神经内分泌癌(small cell neuroendocrine carcinoma of the cervix, SCNEC)比较罕见,其与鳞状细胞癌(SCC)、腺癌等通过临床表现难以...小细胞癌在临床上分为很多种类型,其中以肺癌最为常见,恶性度比较高,预后较差。在妇产科中,宫颈小细胞神经内分泌癌(small cell neuroendocrine carcinoma of the cervix, SCNEC)比较罕见,其与鳞状细胞癌(SCC)、腺癌等通过临床表现难以区分,宫颈中SCNEC和SCC的共存更为少罕见。本文报道1例经阴道镜下病理活检诊断为浸润性SCC,术后病理回报为小细胞神经内分泌癌,伴极少许中分化SCC.展开更多
