Ectopic stratified squamous epithelium in bovine jejunum.
An adult dairy cow developed acute fatal diarrhoea. Necropsy provided no aetiological or morphological cause of the diarrhoea but incidental post-mortem findings included well-circumscribed areas of jejunal squamous epithelium. The cause of this unusual heterotopia is not known, but the lesion may have been of embryological or metaplastic origin.
