To considerate perforation of duodenal diverticula.

The duodenal diverticulum is a relatively frequent entity whose diagnosis has been increased over time with the development of new diagnostic and exploratory techniques. Periampullary diverticula (PAD) were classified as type 1, 2, or 3 according to the position of the major papilla from the endoscopic view: type 1, the major papilla was located inside of the diverticula; type 2, the major papilla was located at the edge of the diverticula; type 3, the major papilla was located outside of the diverticula. Complications of duodenal diverticula include ulceration, bleeding, perforation and inflammation with intestinal obstruction.

Beyond Tumors: Gastric Syphilis Emulating a Gastric Neoplasia.

We present the case of a 35-year-old male with a first-degree family history of gastric cancer (his father was diagnosed at the age of 45), who was presumed to have gastric cancer himself when evaluating the features of his upper endoscopy performed after hematemesis. Surprisingly, no cancer cells were found in the biopsies. Thanks to a different diagnostic suspicion subsequent to performing a full clinical history, a more favorable diagnosis was reached: gastric syphilis.

An uncommon cause of digestive neoplasm: duodenal melanoma.

We present and discuss the case of one patient that presented to the emergency room with abdominal pain in the right hypochondrium radiated to epigastrium and low-grade fever with blood test that shows dissociated colesthasis therefore admitted in the gastroenterology service with choledocholithiasis suspicion. cholangioresonance performed with a sudden stenosis of the bile duct in its intrapancreatic portion due a tumor in the pancreatic head. CT without lessions in other parts of the body.
