涎腺的瘤样病变必须与涎腺真性肿瘤区分开来。在WHO涎腺肿瘤断分类中讨论了7种涎腺瘤样病变:涎腺良性肥大、嗜酸粒细胞增生症、坏死性涎腺化生、良性淋巴上皮病、涎腺导管囊肿、慢性硬化性颌下腺炎及艾滋病的囊性淋巴样增生,对以上瘤样病变的病理学特点分别作出了介绍。 The tumor-like lesions of the parotid gland must be distinguished from the true tumors of the parotid gland. Seven salivary gland-like lesions were discussed in the WHO Salivary Gland Tumor Classification: Benign parotid hypertrophy, eosinophilia, necrotizing parotid metaplasia, benign lymphoepithelial disease, salivary ductal cyst, chronic sclerosing Submandibular gland inflammation and cystic lymphoid hyperplasia of AIDS, introduced the pathological features of the above tumor-like lesions.
