Objective To summarize the clinical data and ultrasonic findings of patients with salivary gland basal cell adenoma (SBCA),in order to enhance the recognition of this disease.Methods We enrolled 14 cases of salivary gland neoplasms who received inpatient treatment including surgical resection and were confirmed as SBCA by pathological examination in Peking University Third Hospital from April 2011 to April 2016.We did a review of the clinical data of these patients,including the site of tumor development,duration,clinical manifestations,and analyzed the ultrasonic findings and the values of indicators.Results Of the participants,4 were males,and 10 were females,with a median age of 56 years old.The 14 lesions found in them were unilateral and solitary,85.7％ (12/14) were located in the parotid gland,14.3％ (2/14) in the submaxillary gland;85.7％ (12/14) had a diameter less than 3 cm;64.3％ (9/14) were oval in shape,21.4％ (3/14)showed slight lobular appearance,and 14.3％ (2/14) were round.All the tumors were found with well-defined border mass,intact capsule,lateral acoustic shadow and enhanced posterior echo.Cystic components shared more than 50％ and less than 50％ in the cystic tumor in 4 and 6 cases of 10 with soft cystic change,respectively;the other 4 cases were found with hard solid mass with homogeneous hypoecho.No calcification was found in them.The vascularity types of the tumors were categorized as grade 0 (3 cases),grade Ⅰ (4 cases),grade Ⅱ (1 case),grade Ⅲ (6 cases).Conclusion The ultrasonic images of SBCA have certain special features,which are contributed to the differential diagnosis of pleomorphic adenoma and Warthin's tumor.But the definite diagnosis still depends on the results of pathological examination.%目的 总结涎腺基底细胞腺瘤(SBCA)的临床资料与超声图像,旨在提高临床对其超声图像特征的认识.方法 选取2011年4月-2016年4月在北京大学第三医院以涎腺肿瘤收治入院并行手术切除且病理证实为SBCA的患者14例,回顾性分析患者的临床资料,包括发病部位、病程和临床表现;并分析超声检查结果,记录指标.结果 14例患者中男4例,女10例;中位年龄56岁.14个病灶均为单侧单发,12例(85.7％)位于腮腺,2例(14.3％)位于颌下腺;12例(85.7％)肿物直径＜3 cm;9例(64.3％)为椭圆形,3例(21.4％)可见浅分叶,2例(14.3％)表现为圆形.病灶均边界清晰,包膜完整,并可见侧方声影,后方回声增强.囊性变肿物中囊性成分≥50％者4例,囊性成分＜50％者6例,质地较软;4例实性病灶多呈均匀低回声,质地较硬;病灶均未见钙化;血流信号分级为0级3例、Ⅰ级4例、Ⅱ级1例、Ⅲ级6例.结论 SBCA超声图像具有一定的特征性,有助于与多形性腺瘤和腺淋巴瘤鉴别诊断,最终诊断仍依靠病理.
