Esophageal Hematoma Mimicking a Large Esophageal Polyp: A Diagnostic Clue of Acquired Hemophilia A

An 85-year-old woman was admitted  for examination of anemia and black stools. A blood test revealed a reduction in her hemoglobin level from 12.7 to 6.6 g/dL (7.9×103 to 4.1×103 mol/L) over a month, suggesting upper gastrointestinal bleeding. Esophagogastroduodenoscopy revealed a large esophageal polyp near the esophagogastric junction (Figure 1). The polyp that was fragile was accidentally resected and removed endoscopically. Histopathological examination of the resected specimen revealed a hematoma containing numerous Enterococcus faecalis bacterial masses without epithelial tissue (Figure 2).
