An 81-year-old man underwent EGD screening, which revealed a depressed lesion on the
posterior side of the cervical esophagus, measuring 5 mm with a marginal elevation
(A). Magnified endoscopy with narrow-band imaging (ME-NBI) showed irregular vessels
with disrupted loop morphology, and a thick green vessel (B). On the basis of the irregular vessel pattern, the lesion was considered squamous
cell carcinoma (SCC) with submucosal invasion. We performed endoscopic submucosal
dissection (C). Pathologic evaluation showed that this lesion consisted of moderately differentiated
SCC, invading the submucosa to a depth of 400 μm (D). The horizontal and vertical margins were negative, but vascular invasion was present.
The patient underwent additional chemoradiotherapy and has been well without recurrence.
