Can a very dark brown birthmark in leg be removed?

I am African American and I was born with a birthmark above my right knee. It is about the size of a lime. It is the same texture as my normal colored skin. I would consider it cafe au lait? It is just very dark. I've always wanted to get it removed, but I didn't think there could be anything done for a birthmark as dark as mine. Can laser treatment help? What are my options?
