title: A unique muscular ring of the jejunum.
abstract: Muscular malformations of the gastrointestinal tract are rare conditions. This communication describes a unique case of such a malformation which developed as a muscular ring in the jejunum. The ring consisted of muscular stricture with a vascular stroma and scattered ganglion cells, covered with pyloric type glands. A similar lesion, which probably represents a hamartoma, has not been reported previously.
