Mesenteric Adenitis Due to<i>Pasteurella pseudotuberculosis</i>in Young People

Abstract

UNTIL a few years ago pseudotuberculosis was thought to be a rare disease, and it received almost no attention in clinical or laboratory diagnosis. Then, in 1953, Masshoff1 and Masshoff and Dölle2 described an abscess-forming reticulocytic lymphadenitis, usually in children operated on for supposed appendicitis.
