多发性肺转移癌呈灰白色


可见肺表面散大的多个大小不一的肿块。灰白色结节状肿块是转移癌的特征。肺转移瘤比原发性肺肿瘤更常见,因为许多其它原发肿瘤可通过血道转移到肺。甚至图示的肺门的结节也是转移癌的结节。瘤结节通常出现在边缘,阻塞作用小。
Multiple variably-sized masses are seen in all lung fields. These tan-white nodules are characteristic for metastatic carcinoma. Metastases to the lungs are more common even than primary lung neoplasms simply because so many other primary tumors can metastasize to the lungs. Even the hilar nodes in this photograph demonstrate nodules of metastatic carcinoma. The nodules are usually in the periphery and do not cause major obstruction.
