Three cases of Warthin's tumors were studied with a scanning electron microscope. The free surface of the epithelium was composed mainly of round or ovoid dome-like structures bearing microvilli and apocrine protrusions. Ciliated epithelial cells were detected in 2 of the tumors. The tumor epithelium encircled various amounts of cellular debris resembling degenerate lymphoid cells. A few tiny cystic spaces were also found. Within the lymphoid stroma, tightly packed lymphocytes, a meshwork of reticulum cells and medullary cord-like structures were observed. Our findings support the concept that Warthin's tumors develop from heterotopic salivary gland ducts within pre-existing lymph nodes.
对3例沃辛瘤进行了扫描电子显微镜研究。上皮的游离面主要由带有微绒毛和顶浆分泌性突起的圆形或卵圆形穹顶状结构组成。在2例肿瘤中检测到纤毛上皮细胞。肿瘤上皮围绕着各种数量的类似变性淋巴细胞的细胞碎片。还发现了一些微小的囊腔。在淋巴间质内，观察到紧密排列的淋巴细胞、网状细胞网络和髓索样结构。我们的研究结果支持沃辛瘤起源于原有淋巴结内异位涎腺导管的观点。
