Is it normal for a shave biopsy to look like this after 4 months? (Photo)

The mole came back as beign. Bottom picture is 2 months after biopsy (it started itching, which made me take a photo) middle 3 months and top is the most recent at 4 months. Seems to be changing and getting fuzzy. Is this just the roots?

Residual nevus

You clearly have visible pigmented nevus within your site of the biopsy. Such finding can happen with a shave biopsy of a deeper nevus. It can be result of either a residual nevus or recurrent nevus at the site of the biopsy. While it is reassuring that the original biopsy came benign, it would be prudent to see a dermatologist to determine if additional re-excision is necessary especially if you are noticing a change in this pigmentation.
