Superficial esophageal lesions detected by endoscopic ultrasound enhanced with submucosal edema

Figure 5 Endoscopy, endoscopic ultrasonography, and tissue examination of an esophageal lesion invading into the submucosa (A, B) and muscularis propria (C, D). A, C: Endoscopic ultrasonography (EUS) imaging: Middle echoic lesion (A) and low echoic lesion (C) invading the submucosa with obvious submucosal edema, as visualized by EUS; B, D: Pathology: Lesion invading into the submucosa (B) and muscularis propria (D) was characterized as squamous epithelium with disappearing muscularis mucosa and submucosal edema, as revealed by pathological examination.
