Non-sebaceous Lymphadenoma of the Salivary Gland: Report of Two Cases and Literature Review

目的:报告2例涎腺非皮脂腺淋巴腺瘤,并总结其临床病理特点。方法:收集2例非皮脂腺淋巴腺瘤的临床资料,常规切片HE染色观察其组织学特点。结果:2例非皮脂腺淋巴腺瘤男女各1例,年龄分别为59岁和50岁,无痛性肿块。镜下见该瘤由上皮成分和显著的淋巴样间质组成,上皮形成实性岛状、腺腔样结构或囊腔样结构,无皮脂腺细胞分化。结论:非皮脂腺淋巴腺瘤是一种罕见的涎腺上皮性良性肿瘤,组织学上具有特征性。

Objective： To report two cases of non -sebaceous lymphadenoma of the salivary gland and to summarize its clinical and pathological features. Methods ： Two cases of non - sebaceous lymphadenoma were investigated by collecting clinical data and observing histological features with a review of literature.
