Hi, I just noticed about 10 small black spots on my scrotum. I only noticed them when I pulled the skin tight. They are about the size of a pen tip, maybe just slightly larger. They are mostly in one area, with a few scattered. They're sort of by a vein, but don't appear to be bloody. They aren't raised and they don't itch or burn. I'm in my late twenties. I've read about angiokeratoma of Fordyce, I guess it could be this, but it doesn't seem quite right. Can you offer any advice?
