It is known that multiple ulcers of the gastric antrum are often accompanied by marked submucosal fibrosis during the healing process, and that this may result in a deformity of the gastric wall. Thus, benign antral ulcers may be misinterpreted as intramural tumors, or even malignant ulcers when the surrounding edema is pronounced and sharply defined. It is possible for an endoscopic ultrasonography (EUS) to detect which layer has a submucosal tumor (SMT) in the five-layer structures of the digestive tract wall. In the diagnosis of SMT of the upper digestive tract, EUS allows for the visualization of the structures underlying the gastrointestinal wall in a noninvasive manner and has a great advantage over conventional modalities such as endoscopy and X-ray examination. The EUS findings of 2 cases of submucosal tumor-like gastric lesion caused by fibrotic ulcer healing are herein reported with a brief review of relevant literature.
