本文收集我室1984—1987年向电镜下见到癌细胞内含有神经内分泌颗粒(NSG)、嗜银染色阳性的11例乳脉癌。其中粘液腺癌1例,浸润性导管癌2例、浸润性癌3例、腺癌2例、小叶癌1例、髓样癌1例、腺鳞癌1例。临床上无一例有类癌综合往症状。这些肿瘤的超微结构特点是:大多数或少数瘤细胞质内含有数量不等的NSG,颗粒通常呈园形或椭园形,直经90～300nm、电子密度不一、中央常见有一致密蕊子、但也有呈均质状,絮状或指纹状,
This article collected our room from 1984 to 1987 to electron microscopy to see cancer cells containing neuroendocrine particles (NSG), silver staining positive 11 cases of breast cancer. Among them, there was 1 case of mucinous adenocarcinoma, 2 cases of invasive ductal carcinoma, 3 cases of invasive carcinoma, 2 cases of adenocarcinoma, 1 case of lobular carcinoma, 1 case of medullary carcinoma, and 1 case of adenosquamous carcinoma. There is no clinical case of carcinoid syndrome. The ultrastructural characteristics of these tumors are: most or a small number of tumors contain heterogeneous amounts of NSG, the particles are usually round or elliptical, straight through 90 ~ 300nm, electron density is different, the central common consistency Mi Rui But there are also homogeneous, floc or fingerprint-like,
