摘　　要：目的:探讨包膜内型甲状腺乳头状癌(EPTC)与经典甲状腺乳头状癌(CPTC)的超声及病理特征的差异。方法:对经手术病理确诊的33例EPTC和85例CPTC的超声表现及其病理特征进行对照分析。33例EPTC按照病理组织学成分的不同分为包膜经典乳头型(E-CPTC)21例和包膜滤泡型(E-FVPTC)12例。结果:21例E-CPTC患者的超声表现,肿块边缘成角18例,回声明显减低17例,伴微钙化13例;E-FVPTC组12例中,肿块边缘光整11例,中等回声9例,周边多见晕圈9例,缺乏微钙化12例;CPTC组85例中,肿块形态不规则9例,回声明显减低66例,伴微钙化51例。E-CPTC和E-FVPTC均可见完整的纤维包膜,CPTC未见明显包膜。E-CPTC、E-FVPTC和CPTC癌细胞内均可见乳头状癌特有的细胞核。结论:EPTC组和CPTC组肿块超声表现相似,E-FVPTC组肿块超声显示相对良性的特征。病理组织学表现,E-CPTC和CPTC具有乳头状结构,E-FVPTC癌细胞完全或几乎完全呈滤泡结构。OBJECTIVE： To investigate the sonographic and pathological features of encapsulated papillary thyroid carcinoma （EPTC） and classical papillary thyroid carcinoma （CPTC）. METHODS： Thirty-three EPTC and 85 CPTC contimed by pathology were enrolled in this study. Thirty-three EPTC were divided into two groups： 21 E-CPTC（encapsulated classical papillary thyroid carcinomas） and 12 E-FVPTC（encapsulated follicular variant papillary thyroid carcinomas）. The sonographic features, pathological features were compared among the three groups. RESULTS： The ultrasound features of 21 E-CPTC were： 18 spiculated margin, 17 markedly hypoechoic, 13 microcalcification 12 E-FVPTC were： 11 smooth margin, 9 isoechoic, 9 more hypoechoic halo, 12 lack of microcalcification; 85 CPTC were： 9 irregular shape, 66 markedly hypoechoic, 51 microcalcification Pathological findings：Both E-CPTC and E-FVPTC had a complete fibrous capsule. CPTC had no capsules. In all three groups there were specific to papillary carcinoma nucleus. CONCLUSIONS： The sonographic features of the E-CPTC and the CPTC are similar the ultrasound features of the E-FVPTC are similar to benign thyroid nodules. Histopathology features were that E-CPTC and CPTC have papillary structure and E-FVPTC has complete or almost complete follicular structure.
