Mallory-Weiss tear during gastric endoscopic submucosal dissection

Figure 1 Esophagogastroduodenoscopy findings. Esophagogastroduod noscopy showed a flat elevated lesion, about 20 mm in size (A), and a polypoid lesion, about 15 mm in size (B), which were detected on the greater curvature of the antrum.

Figure 2 Longitudinal mucosal tears (Mallory-Weiss tear) with active bleeding were detected on the lesser curvature of the gastric corpus.

Figure 3 A total of eight hemoclips were applied for hemostasis.

Figure 4 Macroscopic and microscopic findings of resected specimens. Both lesions were completely removed en bloc (A). Histologically, the first was a papillary carcinoma limited to the mucosal layer and without lymphovascular invasion or involvement of the surgical margins (H&E, × 60) (B), whereas the second lesion was a benign hyperplastic polyp (H&E, × 60) (C).
