Warthin’s瘤是一种较少见的腮腺良性肿瘤。其光镜和透射电镜下的组织结构已较清楚,但对肿瘤内是否有纤毛上皮存在以及淋巴样基质的来源一直有争论。本研究用扫描电子显微镜(SEM)观察了三例Warthin’s瘤。标本分别取自三位年龄为57岁、58岁和71岁的男性患者,将其切碎成组织块,然后进行预固定、再固定、干燥、襞裂、镀金。研究发现,低倍SEM下,肿瘤切面上有数 Warthin’s tumor is a rare benign tumor of the parotid gland. The histological structure under light and transmission electron microscopy is clearer, but there has been debate over the presence of ciliated epithelium in tumors and the origin of lymphoid stroma. In this study, three cases of Warthin’s tumor were observed with a scanning electron microscope (SEM). The specimens were taken from three male patients aged 57, 58 and 71 years old, and they were shredded into tissue blocks, which were then pre-fixed, refixed, dried, chapped, and plated. Study found that at low magnification, there are several tumor sections
