Lee, Choi, Yoon, and Paik: Squamous Cell Carcinomas of the Lung Which Presented as Numerous Polypoid Nodules in the Tracheobronchial Tree: A Case Report


We report a case of squamous cell carcinomas of the lung, which presented as nu-merous polypoid nodules in the tracheobronchial tree. They occurred at two years and 7 months after resection of squamous cell carcinoma, which presented as a lung nodule in the left lower lobe, and at 7 months after resection of tracheal squamous cell carcinoma.

Fig. 1.
A case of squamous cell carcinomas of the lung, which presented as multiple tracheobronchial polyps in a 61-year-old male. A. Initial CT without enhancement axial image mediastinal window shows a 2 cm-sized nodule in the left lower lobe, which was confirmed to be moderately differentiated squamous cell carcinoma by histopathologic examination through wedge resection (arrow). B, C. Follow-up CT without enhancement axial and coronal image mediastinal windows obtained two years after wedge resection show a 1.5-cm-sized mural nodule along the left side of the trachea with adjacent focal tracheal wall thickening. After tracheal resection, moderately differentiated squamous cell carcinoma was detected by histopathologic examination (arrow). D, E. CT was obtained seven months after resection of the tracheal lesion, and the coronal lung window images show innumerable polypoid nodules along the trachea, both main bronchi, and the right bronchus intermedius. Squamous cell carcinoma in situ was diagnosed by histopathologic examination through bronchoscopic biopsy.
