原发性肺透明细胞癌的影像学表现与临床病理对照

目的:探讨原发性肺透明细胞癌(PCCCL)的影像学表现与临床病理特点。方法:回顾分析经手术和/或病理证实的7例PCCCL影像学和临床病理的特点,并复习文献。结果:PCCCL影像学上主要表现为右肺周围性肿块或结节(6/7),结节边缘可见毛刺征,无胸膜凹陷征、空泡征;肿块较大时,边缘光滑,无棘状突起、空洞等征象,1例左肺上叶中心性分叶状肿块,边缘光滑,酷似其它类型肺癌。结论:PCCCL罕见,临床无特异性,病灶较大时,仅有相对影像学特征,确诊依赖病理检查。

Primary clear cell carcinoma of the lung: imaging findings and pathology

Objective:To study the imaging and clincopathologic features of primary clear cell carcinoma of the lung(PCCCL).Methods:Imaging features,including plain chest film(n=7) and CT(n=7),and pathologic findings in 7 patients with pathologically-proved PCCCL were retrospectively analyzed.Related references were reviewed.Results:The main manifestations of imaging in PCCCL appeared as peripheral nodules or masses(6/7) in the right lung.Tiny nodules with coarse spiculate margin,lack of pleural indentation and vacuole sign.When masses of turmor grew larger,smooth margins were found in them.spinous process and cavity were seldom seen.Central mass of left lung superior lobe(n=1),lesion was lobulated,and with smooth margin,which seem others central carcinoma of the lung.Conclusion:PCCCL is a rare disease clinically,it has no specific features.When it grew larger,shadow is a relatively characteristic imaging finding.It is depended on pathologic examination to establish the diagnosis.
