…included clinical findings and cytological features of the lesion are synovial cell sarcoma, undifferentiated fibrosarcoma or neurofibrosarcoma, histiocytic sarcoma or less likely chondrosarcoma.

While we knew all sarcomas are bad, the report gave us some hope that it may be something less aggressive than an

…Maria,

I'm so sorry about your pup. I just saw your comment in a post and am so glad to see you posted here. Have you seen these Histiocytic Sarcoma survivor stories?

Oh I see you started a new topic here! Going over there now.

…almost 4 year old Great Pyrenees had his front left leg amputated Tuesday this last week. He is suspected to have histiocytic sarcoma or a soft tissue sarcoma.

We had been doing very well managing his pain up until Sunday late afternoon/night. He started panting more and

She was diagnosed with Histiocytic Sarcoma on Tuesday after a needle aspiration of a sudden growth on her knee. Our regular vet said we really didn't need to do it because it's very, very

He believes it could have been a second cancer unrelated to the the bone cancer like a lymphoma, or possibly a very rare 1% cancer called Histiocytic Sarcoma.

Yesterday when I thought she was going to go down I was able to have the chance to spend some time with her alone in a private room to say my

Coco had a rare histiocytic sarcoma and there is very little information out there about the disease and I am more than willing to share any information I have learned or experienced.

…you are a good student, because you put her good news above the diagnosis, and that says so much about your awesome attitude at a time like this! 

Histiocytic sarcoma sucks, no doubt. But when we saw more than one long-term survivor in our community, I had to do this post to give others hope. Let me know if it

…that she has in months.  It is really clear how much her diseased limb was hurting her.

Now the terrible news.  Greta's official diagnosis is histiocytic sarcoma, and the lymph node they believed was cancer free after the needle biopsy actually is metastatic cancer.  The surgeon was saddened by the results

…dog like you and if you listen to what he is telling you he will guide you the direction you need to go thats best for him and you. Oh. Coco has Histiocytic Sarcoma which unfortunately is a very aggressive cancer. Sorry for the all the babbling, Hope at least some of it helps.

…prognosis isn't always right. That's really good to keep in mind. It sounds like she's doing way better than they predicted. I'd been researching histiocytic sarcoma and it sounds really hard. (For a while, it looked like Eli might have it, too, so I was reading up on it.) 

It's also good to know that chemo

On April 28th I received the devastating news that she had an aggressive form of cancer called histiocytic sarcoma in that same right leg but it had also spread to her lymph nodes, liver, and lungs. We had her leg removed about a week later, and around 2 weeks

…both Tufts and UW Wisconsin (go Badgers!) are working with it in clinical trials. See:

Tufts: Pilot study of a MEK inhibitor in dogs with histiocytic sarcoma

…. The vet reached back out to me and the "off label" drug is Trametinib look it up. It is a very interesting study or drug used specifically for histiocytic sarcoma. Although the cost is nearly 400 a month and they have to meet certain criteria. I think I may try a month or two in all honesty to see if her

And all these amazing Tripawd dogs who beat histiocytic sarcoma (a poor prognosis)!

A leg cancer tumor in a Tripawd's remaining leg isn't as common as say, osteosarcoma lung metastasis. Again, don't focus on

…10 yr old Coco pretty much is in the same situation and I dont regret the amputation. Unfortunately, she has histiocytic sarcoma. Her prognosis is grave. I plan trying on the chemo. We meet with the oncologolist onTues. Shes getting around wonderfully, see my previous post

…gosh yes we have a lot of members who have used it for histiocytic sarcoma treatment. See these Forums search results for Lomustine and these for CCNU.

I don't have firsthand experience with this so I hope others will

How wonderful to hear that Teddy has done so well!

I'm Murphy's mom - he made it over 4 years after his amputation for periarticular histiocytic sarcoma - he had his right front leg removed.  He had 6 doses of CCNU and then we waited.  X rays, ultrasounds, waiting ... lol and I finally said no

…Teddy is kicking cancer's butt, well this just made my day!!!

OK I guess we need to add him to this article now:

But first, a few more words about Teddy and some pics so we can do that.

Upon further inspection, I got the flash light out and everything and only that section of his skin is really purple. Everywhere

…on the Ultrasounds, X-Rays, etc.

Unfortunately, they were not able to pinpoint the cancer type. They gave me 3 different possibilities: Histiocytic sarcoma, osteosarcoma, or Hemangiosarcoma. What they removed in his leg was a sarcoma. All 3 of these cancer's are very aggressive and the doctor didn’t

…. We are SO GLAD you decided to share your story and celebrate this big milestone. I'm adding your story to our article, "Tripawd Tuesday: Canine Histiocytic Sarcoma Heroes."

That's so wonderful that he's done so well and is loving life. Histiocytic sarcoma is one of those dreaded diagnoses and your superhero

Unfortunately, he was diagnosed with histiocytic sarcoma about one year ago when he was only 8.5 years old. After discussing with the surgeon who actually recommended checking out this website, Charles

…had thought the cancer was Synovial Cell, but the cytology report came back sort of inconclusive. It stated it may be a soft tissue or possibly histiocytic sarcoma and may need additional staining test to rule out histiocytic sarcoma. So this is a little worrisome. In the meantime I'm happy she is getting back

…everyone!

Teddy is day 8 post op from a right forelimb amp for periarticular histiocytic sarcoma. We are confirmed no spread (yay!) and hope to have many more years with our boy (median survival is 30 mo). We start chemo 8/25 - they will

This is certainly not the outcome we were looking for. His surgeon told me to not get ahead of myself that the localized type has better
