In brief: See a Physician
Corns are on the top or sides of toes.
They are caused by an enlargement of bone rubbing against the skin causing a thickining of the skin. A wart is a round lesion caused by a virus. They are elevated on toes, and under the skin on the bottom or the foot. Warts have small black dots called papelli. If you cut down a wart you will get pin point bleeding as warts have their own blood supply.

In brief: Wart
A wart is caused by a virus coming in contact with your skin.
A corn is caused by pressure. They look very similar but a wart usually has "pin point " bleeding where a corn does not.

Your doctor can shave the callus off the top of the lesion and determine whether it is a callus with a core, or an actual wart.
Treatments for each can differ slightly, so find out which you have before you try to treat it with over-the-counter removal pads!
