A couple days ago I was contacted via email by a women that has a pig with a possible cancerous lump on his teat. She said she couldn't afford to treat him and was looking for options on what to do for him.
Being that I have a little experience from Sal's Lump I felt comfortable taking him in.
The owner discovered the lump in June and now it is huge. I have an appointment set up with Murray on Monday. Hopefully it won't be cancerous. Something I find interesting is that Quincy's lump is in the same exact spot as Sal's.
Here's Sal's lump:
Quincy is now in quarentine. He is enjoying some fresh veggies and realizing what real hay tastes like. Here he is in his bluegrass cave:
Any ideas on what his color is classified as?
I'm also worried about his teeth. When I gave him veggies he'd put them in his mouth and do the chewing motion but when the sprig came out of his mouth it was still intact.
When Sal had his mastectomy Murray took fluid from the lump and found it to be a tumor. He didn't even test Quincy's which has me thinking that Quincy is going to need all the luck he can get. I'll know after 4pm how the surgery went. It'll take a couple of days to determine if the lump is cancerous or benign. I'll continue to update with any information I get.
I'm going to try to copy this pic to the post without messing anything up. :-) (I think you said it was fine to use these pics)
- ...what, what, what?
I hope that all works out well, and that the tumor is benign!
- For the love of my girls!
I was wondering if someone (Mel?) can better explain what some of this means. The description area of the report seems a lot different from Sal's and I want to make sure I understand it all.
I would ask Murray these questions but he was busy with patients. He doesn't plan on talking to me again till the margin report comes in and that'll be a couple of days. Below is mostly what I don't understand. Anything else that anyone can explain is welcomed.
I don't understand the bulk of the description area. What does this mean?
"It consist of tubular structures, some of which are cystically dilated with some papillary fronds also observed. Lining the epithelial cells exhibit mild anisocytosis and anisokaryosis with piling observed. Occasion extension below the basement membrane is present. Narrow bands of fibrostroma bisect throughout the mass and the mitotic rate is approximately 1/hpf."
Also, what does "exhibiting low-grade morphologic malignant characteristics." mean?
Source/History: Adult male guinea pig, obtained as a rescue animal. Owner noted mass when obtained, uncertain duration. Mass from right mammary gland. Received 2cm skin-covered specimen with subcutaneous mass.
Within the subcutis of this skin-covered specimen is a well-differentiated but unencapsulated, variable cystic mass. It consist of tubular structures, some of which are cystically dilated with some papillary fronds also observed.
Lining the epithelial cells exhibit mild anisocytosis and anisokaryosis with piling observed. Occasion extension below the basement membrane is present. Narrow bands of fibrostroma bisect throughout the mass and the mitotic rate is approximately 1/hpf.
In the initially examined section, there is a surrounding margin of normal tissue present at natural borders of approximately 0.4cm.
Microscopic Findings: Mammary tubular Adenocarcinoma, well differentiated, low grade.
Prognosis: Fair to possibly long term - guarded.
Comments - Mammary neoplasm's can occur in both male and female guinea pigs. The majority of mammary tumors in guinea pigs are consistent with benign fibroadenomas. Approximately 30% are Adenocarcinoma, as in this case.
They generally behave as local invasive tumors with rare metastasis reported. This mass was well differentiated, exhibiting low-grade morphologic malignant characteristics. Completer remove prior to metastasis may prove curative.
In my initial section there did appear to be a surround margin on normal tissue present; however, additional section have been ordered and will be evaluated for thoroughness. A final report with comments regarding margins will follow.
Borders: - See comments.
**This is a preliminary report, the final report will follow**

(Part of the reason I got spooked was that the normal vet he sees doesn't have any way to do pre-op bloodwork. The place I took one of my hamsters to, they were going to do bloodwork on her, but they couldn't get blood out of her. She probably got some out of them, though.)
Hmm, I should probably have started a new topic?
