tumor? on leopard gecko

Question
Hi,
We have an 16 year old gecko that we received from a friend.  We have only had her about 2 months.  She has developed a red, inflamed tumor like area under her tail.  It seems to be bothering her.  I have noticed that her appetite has not been good for the past 3-4 weeks.  We did not notice the tumor??? until recently.  She is not handled a whole lot, so she could have had it longer than a week.  It appears infected to me.  It is hard to touch, not squishy at all.  I put some neosporin on it.  What else can I do for it? Thank you, Sherri

Hello Sherri,

WOW a 16 year old leopard gecko huh?  That is really getting up there.  Can you post a picture of her for me?  Is it at the vent area?  
Are you sure that it is not a prolapse of that area?  Though you said that it is hard to the touch?  It is probably a cyst then, I would assume.  Can you get her to a vet for analysis?    
What is your setup like, are you using an undertank heater along with a basking light for the warm end?  
What is your substrate, sand, tiles, paper towels?  
Continue to put neosporin on it daily.  If you do have loose substrate take that out & replace it with paper towels so the area doesn't get dirty.
