Malignant and benign gastric ulcer: Endoscopic appearance

Endoscopy showing the differences between the endoscopic appearance of malignant and benign gastric ulcers.
(A) Retroflexed views were required on endoscopy to detect this malignant gastric ulcer of the cardia. Note the absence of folds radiating to the base and the exophytic appearance. Biopsies confirmed the presence of adenocarcinoma.
(B) Benign gastric ulcer in the prepyloric region. The ulcer is well circumscribed, with folds radiating to the ulcer base.
