abstract: We report a case of a male 64 years old with acute abdomen who was operated with the presumptive diagnosis of complicated acute appendicitis. However the patient had black stools for two months, associated with epigastric pain. Endoscopic diagnosis was: Advanced Gastric Cancer: Borrmann II. Histology was informed as: Infiltrating adenocarcinoma intestinal type middlingly differentiated. Surgery findings were: peritonitis with perforated appendicitis in its base: Free coprolites and carcinomatosis. Histology was reported as: ulcerated mucous in caecal appendix, necrosis and perforation of the muscular wall in the base. Mesentery samples were informed with fat tissue involvement by infiltration of tubular adenocarcinoma.middlingly differentiated, suitable with primary gastric cancer.
