What the heck is this new periductal hypoechoic sign? 新的导管周围低回声信号到底代表什么?
CT Diagnosis of Periductal Infiltrating Intrahepatic Cholangiocarcinoma 胆管周围浸润型肝内胆管癌的CT诊断
Purpose To explore the clinicopathological characteristics of periductal stromal sarcoma ( epithelioid type) and its relationship to phyllodes tumor. 目的探讨乳腺上皮样型管周间质肉瘤的临床病理特点及与叶状肿瘤的关系。
Periductal microvessel density and invasion in ductal carcinoma in situ of breast 乳腺导管内癌围管性微血管密度与浸润的关系
The main pathological changes were: evident dilatation of mammary duct, acumulation of large amount of lipoid material in ductal cavity, inflammatory cell infiltration with predominating plasma cells and periductal fibrous tissue proliferation. 主要病理变化是:乳腺集合管明显扩张,腔内大量类脂质物质郁积,大量浆细胞为主的炎症细胞浸润及管周纤维组织增生。
Results The histologic features peculiarly of periductal stromal sarcoma ( epithelioid type) were as follows: ( 1) A predominantly polygonal ( epithelioid) cells stromal proliferated around the epithelial-myoepithelial layer of ducts or ductules devoid of a phyllodes architecture. 结果乳腺管周间质肉瘤(上皮样型)有独特的镜下图像:①显著的多角形(上皮样)细胞绕导管或小管的上皮-肌上皮层呈间质性增生,无叶状结构;
Neoplastic cells of PT are probably derived from periductal fibroblast according to the ultrastructure characters. 叶状肿瘤肿瘤细胞的组织学起源是导管周围成纤维细胞。
