Most squamous cell carcinoma of the lung arises in the large bronchi and causes bronchial obstruction. We report a 74-year-old man with a squamous cell carcinoma of the lung whose roentgenogram revealed a lobar consolidation without collapse. A postmortem examination showed that the tumor cells filled the alveolar spaces completely without destroying the original architecture of the lung. The finding that tumor cells replacing alveolar epithelium, as in bronchioloalveolar cell carcinoma, was not seen throughout the lung. Airway obstruction by the tumor was not observed at any bronchus. These pathological findings seemed to explain the radiological findings.
大多数肺鳞状细胞癌起源于大支气管并导致支气管阻塞。我们报告一例74岁男性肺鳞状细胞癌患者，其X线胸片显示肺叶实变但无肺不张。尸检显示肿瘤细胞完全填充肺泡腔而未破坏肺的原有结构。在整个肺内未发现肿瘤细胞取代肺泡上皮的情况，如细支气管肺泡癌所见。在任何支气管均未观察到肿瘤引起的气道阻塞。这些病理表现似乎可以解释影像学表现。
