I think you mean ringworm, which is a fungus that lives on the skin. However this causes large itchy red or pink circles that get bigger and bigger. Lighter flaky patches could be a form of dermatitis which can be treated with cream, or something called vitiligo, which cause lightening of the skin. This is what Michael Jackson claims made him white!
Light patches on the face are usually fungal infections on the skin. But it would be better to consult a dermatologist.
