We report a case of polycystic disease of the parotid glands. This is a rare disorder and we know of only two previous documented cases in the literature. The disease presents with painless enlargement of one or both parotid glands and is not associated with any clinical abnormality of salivation or with any apparent anomaly of the other salivary glands. Histologically, the overall glandular architecture is preserved but the lobules are all markedly distended by epithelial-lined cysts, which appear to be derived from the intercalated ducts. Characteristic congophilic laminated spheroliths are present within the cystic spaces. The condition must be differentiated from cystic neoplasms, particularly papillary cystic adenocarcinoma, and from various non-neoplastic disorders including sialectasia, retention cysts and lymphoepithelial cysts.
我们报告一例腮腺多囊病。这是一种罕见的疾病，据我们所知，文献中仅有两例先前记录的病例。该疾病表现为一侧或双侧腮腺无痛性肿大，与唾液分泌的任何临床异常或其他唾液腺的任何明显异常均无关。组织学上，整体腺结构得以保留，但小叶均被内衬上皮的囊肿明显扩张，这些囊肿似乎起源于闰管。囊腔内存在特征性的嗜刚果红层状球石。该病症必须与囊性肿瘤，特别是乳头状囊腺癌，以及包括涎腺扩张症、潴留囊肿和淋巴上皮囊肿在内的各种非肿瘤性疾病相鉴别。
