Klinefelter's syndrome as a model for skin changes in venous insufficiency.

Chronic venous insufficiency is a common disease with skin changes, varicosity and leg ulceration. Several theories have been proposed to explain all the changes that occur. We recently saw several patients with Klinefelter's syndrome complicated by leg ulceration and all the typical skin changes of venous insufficiency. The underlying disease was however lacking. They all showed disturbances in their fibrinolytic parameters. In this article we discuss (local) fibrinolytic disturbances as a possible factor in the pathogenesis of the skin changes in chronic venous insufficiency.
