Sclerotherapy of lymphatic cysts of the leg with OK-432.

ABSTRACT

Lymphatic cysts can either represent lymphatic malformations (LMs) or may occur after trauma or operation. Independent of their etiology lymphatic cysts can cause functional impairment and recurrent skin infections. We report the successful use of OK-432 injected transcutanously to treat lymphatic macrocysts. Treatment of LMs with OK-432 has been reported to be a safe and minimally invasive procedure. The underlying mechanism is still unclear but injection leads to an inflammation of the wall resulting in occlusion or shrinkage of the cyst.
