摘要
目的 探讨腮腺硬化性多囊性腺病(SPA)的临床病理特征,以提高对SPA的临床和病理改变的认识.方法 对2例腮腺SPA的临床资料和病理组织学形态特征进行回顾性分析,采用组织化学染色和免疫组织化学染色初步探讨SPA的形态和免疫表型特点,并参考相关文献对其进行总结.结果 腮腺SPA患者的临床表现主要为腮腺无痛性结节状肿块.其组织学表现主要是在玻璃样变硬化胶原组织背景中可见囊性扩张的导管和腺泡,导管中可见大汗腺化生,局灶导管上皮增生伴结构不良.腮腺SPA的免疫组化染色calponin和SMA染色结果可见导管周围有一层肌上皮细胞.结论 腮腺SPA发病率低,目前对病因、发病机制和病程均不明确,如在导管上皮发现显著的非典型现象,术后应对患者加强随访.
Objective To investigate the clinicopathologic features of sclerosing polycystic adenosis(SPA)of salivary gland.Methods The clinical and pathologic profiles of 2 SPA cases were evaluated.Immunohistochemical study was performed on fixed tissues.The biologic behavior was analyzed with follow-up data.Results The main clinical manifestation of patients was parotid painless nodules.Histological features were embedded cystic dilatation of ducts and alveoli as hyaline sclerosis collagen tissue background,catheter see apocrine metaplasia,focal areas of ductal epithelial hyperplasia and dysplasia.Immunohistochemical staining for calponin and SMA staining showed that the catheter had a layer of myoepithelial cells.Conclusion Sclerosing polycystic sialadenopathy of parotid is a rare disease,the cause and course of the disease are not very clear,but the literature reports are atypical ductal epithelial remarkable phenomenon,thus strengthen the follow-up to patients.
