This looks like a cutaneous horn. Most of the time we don't know what causes it. It is a benign growth and doesn't always require treatment, but it will continue to come back over and over after it breaks off. The only way to remove it permanently is to have it surgically removed. For now, I would just keep the area where it fell off clean and apply a topical triple antibiotic ointment to prevent the skin from getting infected.
