Pathological Findings
- Lung squamous cell carcinoma (diagnosed with TBB of the right upper lobe tumor and EBUS-TBNA of metastasized mediastinal lymph node)
- Proliferation of lung squamous cell carcinoma with a tendency to keratinization is observed.
Overall Comment
This was a case of squamous cell carcinoma of the lung (cT1N2M0 stage, IIIA). Bronchoscopy showed that the advanced peripheral squamous cell carcinoma partially progressed towards the central bronchi in a polypoid fashion. The convergence of longitudinal folds suggested that the upper right lobe bronchus was narrowed in a pointed fashion and the lesion extended around the bronchus. In TXI™ technology, structures such as longitudinal folds and fine vascular networks on the mucosa were more enhanced and could be observed more clearly than with white light.
