title: [Nonepithelial malignant degeneration of esophageal duplication].
abstract: A communicating duplication of the distal esophagus was diagnosed in an elderly patient. The lesion was removed and the connection with the esophageal lumen closed. A high grade leiomyosarcoma involving all duplication layers and the right pleural surface was demonstrated. This is the first reported instance of a nonepithelial malignant tumor in an alimentary tract duplication.
