Answer
If it is just depigmenting, there are many reasons for that.  If the skin is actually coming off, then there are other reasons for that.  If it is just lightening, it may be normal.  But there is a condition called Dudley nose where this happens.  Also there is a condition called discoid lupus that can make that happen.
