Abstract
A 62-year-old woman was admitted to our hospital with septic shock due to left submandibular osteomyelitis and cellulitis. Her condition improved following tooth extraction, drainage, and the administration of antibiotics. However, on the 4th day of hospitalization, she went into hemorrhagic shock after defecating a massive tarry stool. Emergency esophagogastroduodenoscopy (EGD) was performed. We found a giant ulcer at the antral greater curvature of the stomach. Computed tomography (CT) revealed that the gastric ulcer had penetrated the pancreas. She had no signs of peritonitis and had a bad general condition. She was therefore managed solely by conservative therapy. She recovered within days.
