Scope:GIF-EZ1500
Case: Squamous Cell Carcinoma
Organ: Esophagus
Patient information: M, 74
Medical history: Smoker
1. WLI
A suspicious reddish lesion can be identified at 6 to 9 o’clock.
2. TXI™ technology
TXI™ technology suggests a larger area that may be interpreted as reflux esophagitis at the first glance.
3. NBI™ technology
However, with NBI technology abnormal intrapapillary capillary loops (IPCLs) can be identified which require closer examination.
4. Near Focus with NBI™ technology
Abnormal IPCLs can be confirmed under near focus, suggesting a squamous cell carcinoma.
5. Lugol staining (WLI)
To confirm the extend of the carcinoma, Lugol staining was applied. Various Lugol-voiding lesions can be identified.
6. Lugol Staining (TXI™ technology)
Under TXI™ technology mode 1, the delineation is supported by stronger color contrast of the carcinoma. The pink color sign is more prominent compared to white light.

Overall Comment
This case presents an incidentally detected squamous cell carcinoma, NBI technology was helpful for detection and characterization in this case. TXI technology in combination with Lugol was helpful to delineate the lesion.
