It could go from a simple skin tag to esophageal cancer, but it is highly likely epiglottis, or a skin tag. Both are non life threatening
Did you ever figure out what it was?
Jello333 is right, it's the epiglottis, so no need to panic.
Sorry, it is not epiglottis, my sister complained about the same thing a while ago and I saw a mini-tongue attached at the back of her throat. It is attached to the base of her tongue and it looks exactly like a tongue. I know what should be there and what shouldn't..this creepy thing is a unique thing. It looks like a secondary tongue. I am so shocked, what if it keeps growing and prevents her from swallowing food or breathing...I really need to get help on this.

It's called the epiglottis, everyone has it.
