this is a "Foople"

Take a look at this nipple and guess where it is located on this person's body...

That's right, you guessed, it....
This slightly hairy "foople" was photographed on a 22 year old woman and is documented here. It has an areola, eccrine glands, and sebaceous glands. Fat tissue was noted at the base of the lesion. This is the first report of supernumerary breast tissue on the foot.
