My cat has developed a lump at vaccine site...most likely VAS... getting a biopsy on Wednesday. After my vet consulted with Cornell, they brought up the *slim* possibility of it being a cryptococcal granuloma, as she was diagnosed with cryptococcosis 3 1/2 years ago and had a stubborn titer..... didn't think to question vet further about the granuloma since we were talking about the biopsy and treatment options if malignant.

Could be.. the skin and/or subcutaneous tissues are involved in about half of crypto cats. Granuloma formation is caused by the cat's cell-mediated immune response to crypto.--- but I don't think the lump is related to crypto - not with such a low titer and after all this time. Does the lump feel soft or hard? Does it feel like its just under the skin and moves with the skin? IOW, if you tent the skin (like a in skin pinch test for dehydration), does the lump move with the skin or is it stationary and feel like its attached to or growing from the muscle? If it moves with the skin, it could very well be an interdermal cyst - (e.g, sebaceous). Eosinophilic granulomas are usually *on* the skin, not under the skin. > didn't think to question vet further about the granuloma since we were > talking about the biopsy and treatment options if malignant. Try to relax a bit and wait until you get the biopsy results. I could be just a cyst. Phil. > > My cat has developed a lump at vaccine site...most likely VAS... getting a > > biopsy on Wednesday.

The vet said she thinks it is under (or in?) a layer of muscle. We are rethinking having the biopsy done at our vet's and just going up to Cornell for it. Will talk to vet on Monday about this... Linda > > Does the lump feel soft or hard?

Hi Linda, Based on your description, size and location of the lump, I'd avoid manipulating the mass as much as possible. I'd have some very serious reservations about manipulating or opening a possibly cancerous mass and leaving it in the cat -- even for a second. I'd image the margins of the mass with ultrasounds -- in a surgical setting -- and opt for an *excisional biopsy* instead of an incisional or needle biopsy. An excisional biopsy removes the entire mass -- which can be sent to a lab for a definitive histopathologic examination. If you opt for an incisional biopsy and the tumor turns out to be cancerous, you'll have to subject Betsy to a second surgery. The first surgery is the most important and has best chance of producing a complete cure. The complete surgical removal of a localized cancerous mass cures more cats than all other treatments combined To my mind, the small size and relatively shallow location of the mass makes an excisional biopsy the wisest choice. Please keep me updated. Good luck. Phil. > > > Does the lump feel soft or hard? Does it feel like its just under the > > skin [quoted text clipped - 52 lines] > > Phil. Phil, We have been rethinking this all weekend.... We were thinking that maybe they can do the biopsy *and* ultrasound/CT scan at the same time, ( I assume the cat will need to be drugged or put to sleep for the ultrasound?) but didn't think about having the whole thing excised at that time. I will be calling my vet in the a.m. and getting the name of the oncologist that she talked with so I can discuss it with them. Thanks again. Linda > > > > Does the lump feel soft or hard?

Linda, Ultrasounds can be performed on awake cats but some cats might need a mild sedative. Cats *definitely* need to be heavily sedated or anesthetized for CT. If you opt for an ultrasound-guided excisional biopsy, of course she'll need to anesthetized. In this case, I think an ultrasound-guided excisional biopsy would be a better choice than CT. Also, if you're having the surgery done at Cornell, their ultrasound machines are fully equipped with Colorflow Doppler and even power Doppler which will show exactly where the major vascular structures are in relation to the mass so they can be avoided during surgery. This greatly reduces bleeding and minimizes the risks of hemorrhage and also shortens operative and anesthetic time. . but > didn't think about having the whole thing excised at that time. I would. The biopsy slice wouldn't be much smaller than the entire lump! I will be > calling my vet in the a.m. and getting the name of the oncologist that she > talked with so I can discuss it with them. Thanks again. > Linda Keep me posted. Good luck. Phil. > > > Does the lump feel soft or hard? Does it feel like its just under the > > skin [quoted text clipped - 52 lines] > > Phil. Question, Phil: If we do an ultrasound pre-excision and the margins are not "even" (or whatever the term meaning "good" is), would they likely choose to do radiation before surgery, without doing a biopsy first to confirm that it *is* cancer?

For example, real time ultrasounds can determine if a mass is growing from within an organ, adhered to the organ, or merely touching the organ. would they likely choose to do > radiation before surgery, without doing a biopsy first to confirm that it > *is* cancer? I don't think your vet would choose radiation before surgery as a prophylactic. Phil > > > > > Does the lump feel soft or hard?

I'm so confused....... Will keep you posted. Linda > What actually is a granuloma? Granulomas are non-cancerous tumors containing granulation tissue. Cats sometimes get eosinphilic granulomas. Eosinphils are cells that are associated with inflammation or allergic reactions. They treat eosinphilic granulomas in cats with steroids such as prednisone. I had a cat that had a spell of rodent ulcers or eosinphilic granulomas on his lip. He was treated with oral prednisone and recovered completely. He never was troubled with them again. The vet said they were called rodent ulcers because at one time they were believed to be caused by eating mice.  SignatureWhen the fog came in on little cat feet last night, it left these little muddy paw prints on the hood of my car. Hi William , I'm not sure that rodent ulcer and eosinphilic granuloma aren't exactly the same thing , AFAIK a rodent ulcer occurs on the top lip and the second is when the bottom lips (trout pout<G>) swells although the cause is the same. Kim gets a reaction to flea treatment but if I dont treat her , she gets a reaction to fleas . Catch 22!
