Adenomatous Intestinal Hyperplasia (Proliferative Ileitis) of Swine

Abstract

A nodular proliferation of the ileal mucosa of a young pig which had suffered an attack of acute enteritis is described and illustrated. The condition is apparently the same as that reported some 37 years ago as ‘intestinal adenoma', but the author prefers the designation of ‘adenomatous intestinal hyperplasia'. The conditions of regional or terminal ileitis of the pig, regional ileitis of man, and muscular hypertrophy of the porcine ileum are reviewed and discussed with particular reference to adenomatous hyperplasia and to one another. A comparison is also made with ‘enzootic intestinal adenocarcinoma’ of hamsters, a disease which has many features similar to this porcine disease.
