Port Wine Stain on chest. But what about this lump?

So I was born with a port wine stain that s partly on my face and goes down to the upper part of my chest. As everyone knows, the blood vessels are very close the surface of the skin so in turn if you get cut it will bleed a lot. However just recently a type of lump/scab has came up in the middle of the stain. It doesn t hurt or anything but when I accidentally pick it off it bleeds like hell. Is there any way to freeze or burn this off? Basically just annoys me.
