Detection of superficial esophageal squamous cell neoplasia by chromoendoscopy-guided confocal laser endomicroscopy

Figure 2 Confocal laser endomicroscopy images of esophageal superficial squamous cell neoplasia. A: Confocal laser endomicroscopy (CLE) scanning; squamous cells (yellow arrow) are homogeneous, while the indicated squamous cells (red arrow) are irregularly arranged with a distinct size and morphology. Capillary leakage of fluorescein sodium is observed; B: Pathological images; the yellow arrow indicates homogeneous cells; the red arrow indicates disordered cell arrangement. The cells have a distinct size and morphology, which is in accordance with CLE.
