title: [Pseudomalignant endoscopic appearance in hyperplastic polyp at esophagogastric junction: case report].
abstract: Hyperplastic polyps are by far the most common benign tumors in the stomach larger than 5mm. Although the malignant potential of hyperplastic gastric polyps was originally denied, a low risk for carcinomatous conversion is now recognized. Its has been recommended that all gastric polyps of 5mm or more in diameter have to be removed. We present here the case of a large hyperplastic gastric polyp located at the esophagogastric junction with endoscopic malignant appearance. The description of its endoscopic and histological characteristics gives us the opportunity to discuss the difficulty of endoscopic diagnosis in the case of gastric polyps and to remind their prognosis.
