u/Aggressive-Tooth-147

Several months ago, I noticed this flesh colored, almost perfectly round spot on my back. It seemed to appear out of nowhere but I don't think it has grown since I discovered it.

Saw a doctor and he seemed surprised and confused by it and just said we'll keep an eye on it.

Would anyone have any idea on what it may be? Should I be concerned, and perhaps move up my next doctor visit?

Thanks!
