Depigmentation of lips and nose - Meghane?
Does Meghane or anyone else have ideas why my girl might be experiencing depigmentation of her lips and nose (photos below)? For background, she is almost 10 years old, has a history of hypothyrodism (but checkups indicate it is well controlled), has early stage kidney disease (again, well controlled), but is otherwise healthy. DH remembers that she had one spot like this last summer (and I think he's right), so maybe it is related to heat, but this is more extensive than before. I am planning to take her in for a checkup but wanted to see if anyone had experience with this first.
