Hi,
I have read your previous post. I do agree that one differential for your case is a skin infection caused by tinea versicolor.The tinea versicolor infection may present as white patches on the body.
Now that you have mentioned white yellow spots in the cheeks, one thing to also consider is seborrheic dermatitis.
Do these lesions itch?
Have you been experiening any oiliness in the skin and scalp?
i have the same thing, its a condition with the pigment in your skin... its harmless and basically jst makes your skin blotchy... you can go to your pediatrician and get pills, i think its 2 pills a day for 3 weeks or something like that. its supposed to blend your pigment back to normal. i never finised taking the pills cuz it doesnt bother me all that much. hope this was helpful in anway
