Need to examine: It is not feasible to provide a meaningful opinion without additional history, physical examination and may be some tests. It would be prudent to see your doctor, preferably a dermatologist. Wish you good health!

Skin color: You are right, vitiligo is an area of skin with no pigment. Light skin may be many things, including a skin fungus! Best to have it looked at. Good luck.
