Turners's syndrome associated with lymphoedema, diagnosed in the newborns.

It is known from literature that about 30% of all female patients with Turner's sydrome have a lymphoedema at the feet and hands. The article discusses as possible reason a congenital defect of the lymphatic system: The vessels are thin-walled, extended and have few valves or none at all. In two phenotypically normal, mature newborn, an analysis of the chromosomes was performed because of marked lymphoedema of the lower extremities, confirming the suspected diagnosis of Turner's syndrome. Hence, it is concluded that Turner's syndrome must always be suspected if there is a congenital lymphoedema of the lower extremities and especially also of the region of the neck.
