Correct Answer: Stomach
Description: Ans. is 'a' i.e., Stomach Dieulafoy's lesion* Dieulafoy's lesion is a medical condition characterized by a large tortuous arteriole most commonly in the stomach wall (submucosal) that erodes and bleeds.* It can cause gastric hemorrhage but is relatively uncommon. It is thought to cause less than 5% of all gastrointestinal bleeds in adults* Dieulafoy's lesions are characterized by a single large tortuous small artery in the submucosa which does not undergo normal branching or a branch with caliber of 1-5 mm (more than 10 times the normal diameter of mucosal capillaries). The lesion bleeds into the gastrointestinal tract through a minute defect in the mucosa which is not a primary ulcer of the mucosa but an erosion likely caused in the submucosal surface by protrusion of the pulsatile arteriole.* Approximately 75% of Dieulafoy's lesions occur in the upper part of the stomach within 6 cm of the gastroesophageal junction, most commonly in the lesser curvature.
