A venous lake is a small blood vessel (vein) in the skin, which over time has become enlarged.
It is thought that long-term sun exposure of the skin causes venous lakes. It is usually seen in people older than 50. They are more common in men than in women.
Venous lakes are common and may affect more than one member of a family, but are not inherited.
They are not contagious or cancerous.
