Just recently since two weeks have noticed a slight white patch on my knee skin. Did consult a GP today but he says it does not look any serious concerns at this stage but to keep a watch if it grows then it could be vitiligo. I have no family history of any skin cancer or vitiligo. And also I have no other patch currently other than on my knee (left leg). If I vaguely remember, I would have seen this small tiny patch one year ago, but thought it was my shave razor mark. So noticed it again, sure pretty sure since one year it has grown in double size. The GP did not provide any medicines as said there is no medical treatment to it. Picture enclosed for easy reference. Please advise. Please advise. As it's a concern. So wanted a skin specialist opinion.
