Carcinoma of the stomach disguised as a benign gastric ulcer.

All gastric ulcerations must be suspected of being gastric carcinoma. Two of the more reliable signs of benignancy have been demonstration of a Hampton's line on upper gastrointestinal barium study and either roentgenographic or endoscopic evidence of ulcer healing. We have reported a case of gastric ulcer with both a Hampton's line and complete healing, which ultimately proved to be malignant.
