This was a small and shallow heel corn.
It didn't give this patient any pain but it would have at some point.
You don't see these foot corns THAT often. They tend to be caused by lots of friction from tough shoe and boot rub.
This heel corn was easily home-removable. The patient didn't know it was there.
(To home remove, all they would need to do would be to slather it in this foot cream and wait for it to fall off a day later)
I scraped off first to reduce the thickness of the surrounding skin. This makes it easier to "pop out" with the instrument.
