[Benign gastric ulcer and ulcerated gastric carcinoma. Considerations on various clinico-endoscopic cases].

Clinical data, X-ray, findings, and the endoscopic and cytologic diagnosis of 94 patients admitted to hospital for gastric ulcer have been reviewed. The purpose of the study was to establish the frequency of malignancy and the reliability and comparative merits of clinical factors, radiology, endoscopy and multiple biopsies in arriving at exact diagnosis. The results show that endoscopy is the most accurate in differentiating benign from malignant gastric ulcers.
