On the basis of 4 cases seen by the author and comparative reports in the literature the following observations were made: 1. Clear cell tumors of the lungs must be considered as semimalignant (or malignana). 2. Malignant degeneration may be associated with a loss of the clear cell character. 3. Clear cell areas are not infrequently seen in common pulmonary carcinomas. 4. Histological differentiation between primary clear cell tumors and metastases (e.g., metastatic hypernephroma) may not be possible. In addition, some general observations on extrapulmonary clear cell tumors will be discussed.
基于作者所诊治的4例病例以及文献中的比较报告，得出以下观察结果：1. 肺透明细胞瘤必须被视为半恶性（或恶性）肿瘤。2. 恶性变可能与透明细胞特征的丧失有关。3. 在常见的肺癌中，透明细胞区域并不少见。4. 原发性透明细胞瘤与转移瘤（如转移性肾细胞癌）之间的组织学鉴别可能无法实现。此外，还将讨论关于肺外透明细胞瘤的一些一般性观察结果。
