摘　　要：目的探讨腮腺鳞状细胞癌(SCC)的声像特征,提高超声诊断水平。方法结合临床与病理资料,回顾性分析6例腮腺SCC病例的超声表现。结果腮腺SCC的内部声像特征:多为囊实性;实性成分为低回声、偏心分布、边界不规则;囊性成分透声不佳。整体声像特征:原发性SCC最大径较转移性SCC大;原发性SCC形态不规则、边界外侵/分叶或不规则、后方回声不变、多血流;转移性SCC形态多规则、边界光滑、后方回声增强、少血流。临床表现:原发性SCC多为增长迅速伴疼痛;转移性SCC为无痛性迅速增长。结论腮腺SCC声像表现多为囊实性,其内实性成分为低回声、偏心分布、边界不规则,囊性成分透声不佳。转移性SCC声像多表现为形态规则、边界光滑,且临床表现为无痛性迅速增长。Objective To investigate the ultrasonographic characteristics of parotid gland squamous cell carcinoma(SCC),and improve the diagnostic ability in this disease with ultrasonography.Methods Combined with clinical and pathological data,the ultrasonic manifestations of 6cases of parotid gland SCC in Peking University Shenzhen Hospital were retrospectively analyzed.Results Sonographic features of internal structure in parotid gland SCC were mostly cystic solid,and which solid components were hypoechoic,eccentric and irregular;the cystic component had poor sonolucent.Overall sonographic features of parotid gland SCC:The maximum diameter of primary SCC was larger than that of metastatic SCC.Primary SCC was characterized by irregular morphology,blurred,lobulated or irregular boundary,no posterior acoustic change,and was hypervascular.Metastatic SCC was characterized by regular morphology,smooth boundary,posterior acoustic enhancement,and was hypovascular.Clinical manifestations:Most primary parotid gland SCC cases were characterized by rapid growth with pain.Metastatic parotid gland SCC cases were painless with rapid growth.Conclusions The ultrasonographic characteristics of parotid gland SCC are mostly cystic and solid mixed.The solid components are hypoechoic,eccentric and irregular,and cystic components are poor sonolucency.Meanwhile,manifestations of metastatic SCC are usually regular shape,smooth boundary,with painless and rapid growth for clinical manifestations.
