a node in one of three groups of thoracic parietal lymph nodes, situated on the thoracic side of the diaphragm and consisting of the anterior set, the middle set, and the posterior set. The anterior set includes about three nodes dorsal to the base of the xiphoid process. The middle set of about three nodes on each side is close to the diaphragmatic entry of the phrenic nerves. The posterior set of diaphragmatic nodes consists of a few nodes on the crura of the diaphragm, connecting with the lumbar nodes and the posterior mediastinal nodes.
