Simplified criteria for diagnosing superficial esophageal squamous neoplasms using Narrow Band Imaging magnifying endoscopy

Figure 4 Representative case of low-grade intraepithelial neoplasia. A: On non-magnifying NBI endoscopy, the lesion demonstrated a well-demarcated brownish area; B: Under magnifying NBI observation, the lesion had only two of the six findings, “intervascular background coloration” and “dilation” of IPCLs; C: The histology from biopsy showed low-grade intraepithelial neoplasia. NBI: Narrow Band Imaging; IPCL: Intrapapillary capillary loop.
