What about a blocked feather follicle? Check out this link:

"As the feather grows, the lump -- caused by the ingrown feather -- also continues to grow until the feather cyst becomes an oval or long swelling."
"A feather cyst can occur anywhere on the birds body."
If you look at the images of blocked feather follicles, some of them are huge for the size of bird. Maybe she got it infected? If she dustbathes as much as ours do, I can only imagine all the dirt and crap she's gotten on it.
That being said, it sure looks like a tumor.
I'm trying to see the glass half full.
Love your outlook but I looked and I just don't see this as a cyst of any kind. Below is what I just posted on the disease forum as no one has run into the problem but it's getting narrowed down to a tumor of some kind.

"Well I've read just about as much as my stomach can handle... sooo many nasty looking photos & trying to figure this out!
I did find this on one forum:
"...unfortunately, as my vet informed me last year when I took in a hen with a lump at the base of her tail, chickens can suffer from upwards of 300 different types of tumors and cysts. If it is a solid mass and does not feel like fluid, it is most likely a tumor and will prove fatal eventually. I've had three hens with tumors over the years, all died shortly after the mass was discovered. The thing with tumors is, the chicken will carry on normally and not act or look ill until the thing just takes so much of their energy that they pass away. Cysts have a better outlook, they can usually be drained, but you never know if they will reoccur. "
Don't know the poster or if it's true but sounds possible... I just hate the idea of putting this girl down, and if we do and I get a good look at this thing and figure out I could have let her live I'll really have a bad night.
but on the other side...I've read on a ton of sites (like research docs) that there are many tumors caused by a virus. That's just dandy. NOT. I'm not seeing a good way out for this good layer.
