I don't see anything alarming, but then I'm an old guy and my skin is in general showing wear-and-tear.
If it doesn't itch or spread I would just ignore.
That said, and being an old guy, I usually visit a dermatologist once a year as part of my annual physical exam. I point to lots of blemishes, commonly called "age spots" and the doctor either freezes them to help remove then or says "nothing to worry about" and I suppose the cost to remove them exceeds the benefit - regardless who pays. So, mostly limit cosmetic work to my face, and a few spots on my back... nothing on my legs, but then I'm a old...oh yes, I already told you that.
It may be my poor eyesight or the quality of the picture, but your concern looks to be about a minor blemish - hope is nothing worse. Checking with a doctor who will make a physical test is always the best when we are worried.
Hi, my daughter had exactly the same thing, after a biopsy she was diagnosed with a rare skin cancer called dermatoma fibrosarcoma protuberant. (Dfsp) for short. Please go and get it checked out and removed as soon as you can, it's very rare and our dermatologist had never heard of it before.
was your daughter able to scratch it off and it would always come back??
