She told me about it whilst I was washing her hair, so I had a look and it is a tiny growth about the size of one of those little decorative balls you get for cakes (sorry crap comparision).
Anyway, it is really hard to describe but it is fleshy and pink and looks like it will bleed when you touch it but it didn't. She said it didn't hurt.
It definatly isn't any skin condition I have ever come across before and is just really odd, jelly and fleshy like.
