肺乳头状腺癌影像学表现的病理学基础分析

目的　分析肺乳头状腺癌影像学表现与病理组织学基础之间的关系。方法　将同期手术、病理证实的2 6 1例原发性肺腺癌中的 10例肺乳头状腺癌的影像学表现与病理组织学表现进行对照分析。结果　影像学上表现的结节或肿块征象在病理组织学上为乳头状的肿瘤以及肺组织被扭曲、破坏的结构 ;影像学上病变周围出现的磨玻璃状阴影 ,在病理组织学上则反应肿瘤细胞沿肺泡壁生长或阻塞肺泡引起的阻塞性肺炎改变 ;影像学上出现的卫星结节对应病理组织学上的阻塞性肺炎、细支气管炎或细支气管脓肿。结论　肺乳头状腺癌作为肺腺癌的一个亚型发生比例比较少。生长方式与支气管肺泡癌相似 ,容易被误诊 ,尤其在细胞活检时更容易误诊

An Analysis of the Pathological Basis of Imaging Manifestation in Lung Papillary Adenocarcinoma

Puropose To study the relationship betwwen imaging manifestation of lung papillary carcinoma and its pathological findings. Methods 10 cases of lung papillary adenocarcinoma out of 261 cases of primary lung adenocarcinoma that were verified by pathologic examination after operation were acquired. The imaging manifestation and pathological finding were studied comparatively. Results The nodular and mass in image indicate the papillary carcinoid tissue and twisted destructed structure; The frosted glass\|liking shadows around the mass in film reflect the infiltration of tumor cell along the alveolar and obstructive inflammation consequently; The satellite nodular sign in film represent the obstructive pneumonia,bronchiolitis or bronchiolar abscess correspondingly in pathology. Conclusion Lung papillary adenocarcinoma,as a subset lung adenocarcinorma,has a low moebidity. Since the growing manner of similar to that of bronchoalveolar cell carcinoma,it is likely to be misdiagnosed,especially for biopsy.
