To our knowledge, there are currently no reports in the literature that discuss the fine structure of the striated ducts of the human parotid gland. Papillary cystadenoma lymphomatosum (Warthin's tumor) is a benigh neoplasm found almost exclusively in the parotid gland that represents about 16% of all neoplasms of the gland. This neoplasm is believed to arise from the striated and/or excretory ducts, but there are contradictions with regard to the proposed origin and the cellular composition of some Warthin's tumors. Tissue was obtained at the time of surgery and examined ultrastructurally and cytochemically for the localization of alkaline phosphatase and adenosine triphosphatase. Myoepithelial cells were found ultrastructurally and cytochemically on the proximal aspect of the striated duct, with their cell bodies situated at the junction of the striated and intercalated ducts. Two Warthin's tumors were observed with cells that were structurally and cytochemically similar to myoepithelial cells.
据我们所知，目前文献中尚无关于人类腮腺纹状管精细结构的报道。乳头状囊腺瘤淋巴瘤（沃辛瘤）是一种几乎仅见于腮腺的良性肿瘤，约占腮腺所有肿瘤的16%。该肿瘤被认为起源于纹状管和/或排泄管，但关于其假定起源及某些沃辛瘤的细胞组成存在矛盾之处。手术时获取组织，并对其进行超微结构和细胞化学检查，以确定碱性磷酸酶和三磷酸腺苷酶的定位。在超微结构和细胞化学检查中，在纹状管近端发现了肌上皮细胞，其细胞体位于纹状管和闰管的交界处。观察到两例沃辛瘤，其细胞在结构和细胞化学方面与肌上皮细胞相似。
