Brief Answer:
Not Tuberous sclerosis

Detailed Answer:
Hello
Thanks for the query.
Tuberous sclerosis is multi system disease.
It does not manifest only with skin lesion.
The skin lesions of tuberous sclerosis are not white.
They are typically called as ash leaf macules.
White patches in neonates are mainly of fungal origin.
They are very common and can be treated easily.
I would like to see a photograph of the patches.
This will help me in giving a closer diagnosis.
Please upload a photograph.
Waiting for your response.
Thank you.

Brief Answer:
Not Tuberous sclerosis

Detailed Answer:
Hello
Thanks for the photograph.
It is looking like nevus depigmentosus.
It is a normal condition and is quiet common in children.
Just keep a note on the lesions.
If they increase in size or number then vitiligo would be considered as the most probable diagnosis.
It is definitely not tuberous sclerosis.
Just relax and let me know if you have any other doubts.
Thank you.

Melgain will help

It will definitely help.
Let me know if you have any other doubt.
