A Case Report of Foreign body Presents Difficulties in Diifferentiation from Submucosal Tumor of the Residual Stomach

Yuji Masaki and Toshimasa Okada

Department of Surgery, Okamura Isshindou Hospital

A 54-year-old man was admitted to our hospital for further examination of a left upper abdominal mass, which was found incidentally by abdominal CT following acute pancreatitis. He had a past history of undergoing a distal partial gastrectomy for perforation of a gastric ulcer in Brazil 24 years ago. Upper gastrointestinal endoscopic examination showed a typical submucosal tumor of the residual stomach. In abdominal CT, MRI, and angiography, it was difficult to distinguish between submucosal tumor and other nonepithelial tumors. The resected specimen revealed foreign body which was derived from gauze left from the previous gastrectomy. Foreign body should be suspected in case of unknown mass with a history of laparotomy.
