title: [Characteristics of morphologic diagnosis of malignant transformation of chronic duodenal ulcer during its surgical treatment].
abstract: Under investigation were results of gastric biopsies, tissues of ulcers dissected during operation and findings of an analysis of preparations in paraffin sections. Findings of all the three diagnostic methods were shown to be completely identical in 63 patients (chronic ulcer in 54 of them, malignant ulcer--in 9). Errors took place in 17 patients. Causes of the errors are discussed. Practical recommendations are given.
