For the past five years I've had a growth on the cuticle of my left foot's big toe that literally looks like a distorted small foot. It is around the size of a larger wart but it has 5 distinct "fingers" which you can almost see nails when you look at it up close. I've accidentally hit it once and it simply turned black and fell off, but it later grew back once again in the same location. Do you have any idea of what this may be, I wish I could submit a picture along with this request, but I don't know how to do that.
It could be several things. Some warts do have Mickey Mouse ears and other appendages on them. It could be a cutaneous horn. Or you may have a small spicule of nail growing up through the epinychium. Of course there are some tumors that sort of look like that.
You might have it look at by a podiatrist or plastic surgeon.
