Periampullary Variceal Bleeding: An Atypical Complication of Portal Hypertension

Variceal bleeding remains a fatal complication of portal hypertension. Periampullary varices are rare and, due to their location, are difficult to diagnose and treat. Similar to esophagogastric varices, they are the result of high portosystemic pressures secondary to intrahepatic causes such as cirrhosis and extrahepatic causes such as portal or splenic vein thrombosis. We report a case of a periampullary varix resulting in hemobilia during endoscopic retrograde cholangiopancreatography (ERCP).

Gastrointestinal Tuberculosis Presenting as Malnutrition and Distal Colonic Bowel Obstruction

Gastrointestinal (GI) tuberculosis (TB) is rare and can occur in the context of active pulmonary disease or as a primary infection with no pulmonary symptoms. It typically presents with vague abdominal symptoms, making it difficult to discern from alternative disease processes. Although the ileocecal region is the most commonly affected site, tuberculous enteritis can involve any aspect of the GI tract. To demonstrate the importance of maintaining a high clinical suspicion for the disease, we present a case of GI TB presenting as severe malnutrition and segmental colitis of the left colon.

Incidentally Discovered Extranodal Marginal Zone B-Cell Lymphoma of Mucosa-Associated Lymphoid Tissue in the Colon

We present a case of colonic mucosa-associated lymphoid tissue (MALT) lymphoma in a 62-year-old woman diagnosed after a positive test for fecal occult blood.
