strange lump on leg

I hope someone can help me here, though I know my best bet is probably to see a dermatologist.
I have an odd lump on the left side of my left thigh. It might be a wart, but I had a seed wart on my hand which was very different. This feels like a thick callous, but raised slightly and concentrated in an area about the size of a pea. It is darker than the skin around it, but not really pigmented differently, not like a mole. I don't remember a specific date it appeared, maybe five years ago.
I was just wondering if anyone has experienced something similar or knows what it is. Thanks!

Is it hard?  Does it itch sometimes?  Or if you apply pressure does it hurt at all?  I have something very similar on my back near my shoulder but mine is about the size of a dime.  Doctors that have just looked at it beleive it is a cyst (gangloin).  Ley me know what you find out...

I have the same thing. Mine has a little whole in the middle though. I dont know what it is, but when it first showed up 4 or 5 years ago it was really swollen, then now its a dark hard spot with no feeling in the middle of it. I really need some advice 2!
