Dieulafoy Lesion of the Colon: A Rare Finding During Colonoscopy.

Dieulafoy lesions are common dilated submucosal vessels that can present with gastrointestinal (GI) bleeding. These lesions are usually found in the stomach or esophagus and colonic Dieulafoy lesions are very rare. Clinical presentation can vary from mild non-threatening GI bleeding to massive and recurrent hemorrhage. Here, we discuss a case of a 71-year-old female patient who presented with a bright red bleed per rectum. Colonoscopy was performed, which revealed a bleeding Dieulafoy lesion in the descending colon with clotted blood in the transverse and descending colon. In this article, we will also review the literature related to the epidemiology, clinical presentation, diagnosis, and management of Dieulafoy lesions.

A Case of Heterotopic Gastric Tissue in Duodenal Bulb: An Interesting Endoscopic Finding.

Gastric heterotopia (GH) is a rare, congenital condition where gastric tissue is found outside of its normal location in the gastric mucosa. It is usually benign and can be found throughout the gastrointestinal (GI) tract. In the duodenum, it is usually seen as multiple polyps, specifically in the duodenal bulb. Here, we discuss the case of a 67-year-old male patient who presented with hematemesis, melena, and abdominal pain. Esophagogastroduodenoscopy (EGD) and biopsy revealed a mass consisting of heterotopic gastric mucosa along with an esophageal ulcer. In this article, we will discuss the literature related to the clinical presentation, diagnosis, and management of GH.
