Abstract

The salivary duct system in the setting of chronic sialadenitis is predisposed to undergo a variety of cellular modifications. This report documents a rare type of metaplasia of a parotid benign lymphoepithelial lesion. Epimyoepithelial islands showing focal sebaceous differentiation and pure sebaceous cell nests in addition to their usual histologic appearance were noted throughout the lesion. The possible pathogenesis is discussed through a review of the literature.

摘要

慢性涎腺炎背景下的涎腺导管系统易于发生多种细胞改变。本报告记录了腮腺良性淋巴上皮病变一种罕见的化生类型。在整个病变中，除了其通常的组织学表现外，还观察到肌上皮岛出现局灶性皮脂腺分化以及纯皮脂腺细胞巢。通过文献回顾对可能的发病机制进行了讨论。
