HETEROTOPIC PANCREAS IN THE STOMACH

Clinicopathologic analysis of 29 cases

Abstract

Thirty lesions of heterotopic pancreas of the stomach, that were found in 29 patients, were reviewed from clinicopathologic view point. The heterotopic pancreas as divided into two macroscopic types, α and β, which were different from each other in their location, size, mainly affected layer in the gastric wall, and constituents of the lesion. Acinic element of the pancreas was found in the lamina propria mucosae in 40% of the cases, indicating the possibility of successful endoscopic biopsies. Central concavities of the lesion were found in 57%, showing considerable variations in their configurations, of which one should be aware in diagnostic roentgenography and endoscopy.
