Peptic ulcers. A, The stomach is opened and laid flat, revealing several large punched-out gastric ulcers. B, A cross-section of a peptic ulcer, illustrating the four layers: fibrin (black arrowhead), neutrophils (black arrow), granulation tissue (white arrowhead), and fibrosis (white arrow). C, A duodenal peptic ulcer that has perforated the wall, producing peritonitis. The liver is cirrhotic (an incidental finding unrelated to the duodenal peptic ulcer).
