摘要： 本文报道了5例基底细胞癌的电镜观察.电镜下细胞数量多,排列密集.细胞之间的连接方式以紧密连接和中间连接为主,和正常上皮相比,基底细胞癌的桥粒虽然存在,但其数量明显减少,发育不成熟,结构不正常,电子密度也低.可见少数核丝分裂相.在色素性基底细胞癌中可见色素细胞或噬色素细胞.电镜结果提示基底细胞癌来源于上皮细胞,但保留了上皮胚芽时期的某些形态特征.

Abstract: The paper reports the ultrastructural changes of 5 cases of basal cell carcinoma. Under EM there were many cells which were closely aggregated. The junctions between the cells were mainly tight and intermediate. In comparison with the normal basal cells, although the desmosomes in basal cell carcinoma were observed their numbers reduced markedly, and they were immature with abnormal structure and low electron density. Individual cells were in mitotic phase. In pigmented basal cell carcinoma there were melanocytes and melanophages. The above-mentioned EM findings suggest that basal cell carcinoma originates from epithelial cells and retains some features of embryonic epithelium.
