[Clinicopathological study of 65 cases of aberrant pancreas in the stomach]

Sixty-five cases of aberrant pancreas in the gastric wall in 9,650 resected stomach were investigated clinicopathologically. Average age was 44.5 and male to female ratio was 3.5 to 1. Eighty-eight per-cent of the lesions were found in the pylorus and antrum, and the lesions were frequently found in the posterior wall, anterior wall and greater curvature. The size of the lesions varied from 0.7 cm to 4.5 cm in diameter and 89.1% of them were within 3 cm in diameter. The protruded lesions were usually found in the space between submucosa and propria muscularis, and the flat-elevated ones were frequently found in the space between propria muscularis and subserosa. The histological incidence of Heinrich type I, II and III were 38.8%, 52.2% and 9.0%, respectively. There was no case of malignant change in the present series.
