It is a low-grade malignancy that is the second most common tracheal malignancy at histology (33%) after squamous cell carcinoma (48%). 其为低级别恶性肿瘤,在组织学上第二常见的支气管恶性肿瘤,仅次于鳞状细胞癌。 Adenoid cystic carcinomas usually arise in the lower trachea. Others are found in the mainstem bronchi; lobar bronchi; or, rarely, in the segmental bronchi and extrathoracic trachea. The tumor has a striking tendency toward submucosal extension that manifests as an intraluminal mass of soft-tissue attenuation with extension through the tracheal wall, a diffuse or circumferential wall thickening of the trachea, a soft-tissue mass filling the airway, or a homogeneous mass encircling the trachea with wall thickening in the transverse and longitudinal planes. The longitudinal extent of the tumor is greater than its transaxial extent. Although the most common site of the tumor in the trachea has been reported to be the posterolateral wall, the anterolateral wall. mild shifting of ... to the left side:轻度向左移位 luminal:官腔 intraluminal [ɪntræ'lu:mɪnəl] adj.管腔内的 salivary [səˈlaɪvəri] adj.唾腺;唾液的 感谢Eun Jin Chae, M.D. / Asan Medical Center, University of Ulsan College of Medicine |
