Hey guys, wanted to know if you could ID an issue. I visited a friend the other day who has several burms and he asked me to identify a mass in one of them. I'm at a loss!

Here's the facts:

She's a Female
Mass has been there since June or so
She is eating regularly, but this lump is not a recent meal...
Doesn't appear to have pooped recently
Mass is pretty hard and lumpy
It doesn't extend to the cloaca as I would expect if it was impacted feces
Appears healthy in every other way

Here's the pics:



Any ideas I can pass on to him would be helpful. I'm very curious myself!]
