Brief Answer:
It looks like vitiligo but may be also fungal infection.

Detailed Answer:

Hello,

I read carefully your question and I saw the photos that you posted.

The light colored patches seem very much like vitiligo. But in order to decide diagnoses, she will need to be followed by a rheumathologist and do some tests.

I think that meanwhile you wait for the appointment of a specialist, you rule out a possible fungal infection. This is another very possible option of diagnoses, because vitiligo is it very uncommon to appear so fast. Apply Ketoconazole 2% locally, twice/day for 1-2 weeks. If improved, then it is not vitiligo.

Hope this is helpful.
Let me know if you need more clarifications.

Brief Answer:
Vit D is not associated with Vitiligo and also does not cause those lesions

Detailed Answer:
Hello,

Vit D deficiency does not cause skin lesions like that but gives more bone development problems.

If it is the vitiligo, there are several therapies that can be used, like local creams, photo therapy, oral steroids, ect. But again, the local rheumathologist will follow you step by step once the diagnoses is decided.

Let me know if you have other questions or concerns.
