已有几例宫颈类癌和神经上皮癌的组织学和超微结构特征的描叙,这些肿瘤推测是从宫颈的嗜银细胞而来。为 APUD(胺前体摄入和脱羧作用)细胞系统的组成部分。近来已在内膜癌中发现嗜银颗粒;光镜所见多为高度或中度分化的腺癌。仅1例为64岁伴神经内分泌特征的内膜小细胞癌。本文报告1例含有神经分泌颗粒的内膜小细胞癌。
There have been several histological and ultrastructural features of cervical carcinomas and neuroepithelial carcinomas, presumably derived from argyrophilic cells in the cervix. Is part of the cellular system of APUD (amine precursor uptake and decarboxylation). Recently, there have been found in endometrial silver-banking particles; most of the light microscope seen as highly or moderately differentiated adenocarcinoma. Only 1 case was 64-year-old with endocrine small cell carcinoma with neuroendocrine features. This article reports 1 case of small cell carcinoma of the intima containing neurosecretory granules.
