A foreign body granuloma after gastric perforation mimicking peritoneal dissemination of gastric cancer: report of a case.
This report presents the case of a 58-year-old man who was found to have foreign body granulomas (FBGs) that mimicked disseminated gastric cancer. The patient presented with a severe attack of acute upper abdominal pain, was admitted to the hospital, and thereafter underwent an immediate laparotomy due to a diagnosis of an upper gastrointestinal perforation. Follow-up endoscopy revealed an ulcer scar measuring 2 cm in size in the anterior wall of the middle stomach. The pathological examination of biopsy specimens taken around the scar revealed well to poorly differentiated adenocarcinoma. At the time of reoperation performed 2 months after the first operation, many small white granulomas were observed which were thought to be the result of peritoneal dissemination of the gastric cancer. However, both the cytology of the Douglas washing and pathological examination of frozen section specimens were negative for carcinoma, and therefore a distal gastrectomy was performed. The pathological examination revealed the presence of FBGs. In this rare case, the FBGs formed shortly after surgery and were difficult to distinguish from disseminated cancer.
