Figure

• 

  Fig. 1. Index colonoscopic findings. (A, B) Multiple submucosal tumors are observed between 20 cm and 40 cm from the anal verge. Some lesions show hyperemia. (C, F) Endoscopic mucosal resection is being performed on the largest lesion with easy-touch bleeding.

• 

  Fig. 2. Microscopic finding. Cystic structure with surrounding fibrosis in the submucosal layer is seen. Marked hemorrhage in the mucosa layer is also observed (H&E, ×100).

• 

  Fig. 3. Computed tomography scan. Transverse (A) and coronal (B) views show multiple isolated intramural air-filled cystic lesions (arrows) in the left-sided colon on lung window settings (width of 1,500 HU and level of −400 HU).

• 

  Fig. 4. Findings of the second colonoscopic examination performed 6 months after the index colonoscopy. (A, B) Although multiple submucosal tumors are still noted, the degree of distension and congestion of individual lesions seem to have decreased. Endoscopic mucosal resection is being performed on the most hyperemic lesion (C).

• 

  Fig. 5. Findings of the third colonoscopic examination performed 24 months after the index colonoscopy. No abnormal findings are observed except for the whitish scars due to previous endoscopic mucosal resections.
