Abstract

Delgado Fernando, Garbaccio Sergio, Morris Winston, Blanco Viera and Francisco J

The present report describes the accidental detection of an ectopic columnar epithelium with interspersed gobblet-cells and a light smooth muscle layer in an ileocaecal lymph node, from an adult Aberdeen Angus crossbreed cow, which was infected with Mycobacterium bovis. The morphological features reminded intestinal epithelium, and an intestinal choristoma was diagnosed.
