Bad shed and possible scale rot?

Hard to say from the pics but I think it's the same thing that affects one of my girls- I have always thought that it is part of a bad shed, it looks like part of the scale was shed leaving the pigmentation (or bottom layer) behind....if you look at the shed it is complete, but certain scales (in the shed) are lighter....kind of the opposite of what you see on the snake.

Anyways, if that made no sense: it is nothing to worry about, it will be gone next shed. The scales affected may get rough and dry looking in my experience. It is not scale rot like I have ever seen, one of my snakes had a mild case of scale rot and it looks nothing like that.

Good luck.
