Doesn't sound horrible, just serious; do not be scared to death! Limited
metastatic potential is a promising trait.
I had an Asslan of Robinsway son, out of a Lance daughter (that darned Lance
just about destroyed our breed, eh?-----JOKING!!) who had one of these removed
from his pastern at about 5 years of age. No recurrence; no further problems.
If it does recur, however, I would probably go get another vet's opinion. Your
current vet may just know what to worry about and what not to worry about.
From the Merck Veterinary Manual:
Hemangiopericytomas (canine spindle-cell sarcoma, canine malignant fibrous
histiocytoma, canine neurofibrosarcoma, canine perineuroma) are common in dogs
and rare in cats (if they occur at all). This tumor was initially named because
it was thought to be derived from fibroblastic cells that surround small
vessels; however, the appropriateness of the name remains a topic of debate.
These tumors develop most commonly on the distal extremities and thorax of
older dogs. Females appear to be predisposed, and Siberian Huskies, mixed-breed
dogs, Irish Setters, and German Shepherds are most at risk. Hemangiopericytomas
typically present as firm, multilobulated, solitary lesions with irregular
borders, most commonly in the subcutaneous fat but sometimes in the dermis.
They are of intermediate malignancy and have limited metastatic potential.
Complete excision is the treatment of choice but, due to their infiltrative
nature, ~30% recur. If the first excision of any sarcoma is not adequate,
followup surgery to completely remove the tumor bed is indicated. At surgery,
intralesional chemotherapy with carboplatin and intraoperative radiation
therapy may improve the tumor-free interval. Followup external beam radiation
therapy may also be considered as an option to control local recurrence
following incomplete excision or narrow margins.

Subject: Hemangiopericytoma
Just wondering if anyone has dealt with this type of tumor? I had a lump
removed from one of my bitches' elbows 10 days ago and the lab said it
was a Hemangiopericytoma. My vet didn't act like it was that big of a
deal, except they keep coming back and more invasive and must be removed
immediately upon their return. I got on the internet yesterday and one
of the articles I read mentioned cancer, radiation and amputation. Now
I'm scared to death. I also read on Shirley's Wellness Cafe where
someone treated one holistically with favorable results. I'd really like
to hear if anyone else has gone through this with a dog and what happened
with your animal. Also, any useful articles would be appreciated
