Leopard gecko inflammation

Question
We have an older (10 years) leopard gecko at our workplace, and he has recently developed a bulging inflammation around his genitals. Since he's sort of a "mascot", no one person really is his owner, or in charge of his health. We covered his sand with paper towel in case sand grains were causing the irritation, and given him a damp, moss-lined shelter for comfort, but the inflammation is getting bigger. Is this something that needs to be checked out by a vet?

Answer
Hi Kyla,

If what you are seeing is prolapsed tissue then yes, it is a vet requiring situation and the sooner the better. A prolapse is internal tissue that is protruding from the vent (his anal opening). It can be either reproductive tissue or part of  the cloaca which is the last part of the digestive system. The circulation tends to be cut off and the tissue is very prone to injury, drying, infection and necrosis (tissue death). Once that happens, it is a far more serious condition to treat. A vet can identify the tissue type, clean it and usually replace it inside the body if it is caught in time. In the meanwhile, try to keep the tissue clean, un-injured and moist. A water based lubricant like KY is ideal but even olive or mineral oil  will do.
Now, if this looks more like a lump that is forming under his normal skin then you may still likely require a vet but it is less of an emergency then a prolapse.
Keeping him off the sand was a good first step. You can also soak him in a bit of tepid water to clean the area a abit more. Human topical antibiotic ointment can be used on the area (and on a prolapse as well). Unfortunately, reptile pus forms as a solid so abscesses do not tend to drain on their own. If it has been getting obviously larger then you might not want to wait too much longer before seeking veterinary help. At least you have a few people who are, hopefully, willing to share the cost a bit. The site called Herp Vet Connection can help you locate a reptile vet in your area. Good luck to your little mascot.
