Lump on my dog, Cytology Report and what they want to do.

Took my little girl down to the vet the other day because we noticed a bump on her side. They did a fine needle aspirate of it and we just got the cytology report back.

The vet said it could be a benign fibroma which they usually wouldn't worry much about unless it grows big and causes problems or possibly a soft tissue sarcoma which could become invasive and once it grows bigger its much harder to remove for good as it can grow back if not removed sooner than later. But they don't know for sure unless we remove it with surgery and have a biopsy/histologic evaluation.

Below is the cytology report,

"Source: 4 slides from semi-firm movable subcutaneous mass on right side of thorax about 2cm in diameter.

Microscopic description:The sample is highly cellular, consisting of numerous mesenchymal cells and low numbers of inflammatory cells (few neutrophils and macrophages) on a highly proteinaceous background with free lipid. Some collagen is noted. The mesenchymal cells are spindled with moderately basophilic cytoplasm. Their nuclei are ovoid and display moderate anisokaryosis. They have stippled chromatin and some haver prominent nucleoli. Few mitotic figures are observed.

Findings: Atypical mesenchymal proliferation with mild mixed cell inflammation

Comments: the mesenchymal cells could be a reactive fibroblast population since a mild degree of inflammation is present; however, they display moderate nuclear atypia, including increased mitotic activity. Other differentials include a benign fibroma or hamartoma or a soft tissue sarcoma. It is difficult to discern reactive vs neoplastic mesenchymal populations on cytology when inflammation is present.

In most cases, soft tissue sarcomas do not readily metastasize, but can be locally invasive and some may recur. Biopsy and histologic evaluation are recommended to discern a reactive vs neoplastic mesenchymal population."

My vet doc then added,

"Pathologist is concerned about reactive fibroblast, benign fibroma, hamartoma or soft tissue sarcoma. Of all those differential diagnosis, the soft tissue sarcoma is the one we need to be concerned of. "

They came back with a treatment plan and what it would cost to have it removed and evaluated to see exactly what it is. They want around $1500-1700 total. I was wondering if this is normal for pricing or what anyone's opinion is on the cytology report or anyone that has maybe gone through this.

I want to do whatever she needs but I don't want to get taking for a run and put her through surgery if it could be nothing serious.

Was hoping the fine needle aspirate would have given more answers since we had to pay $285 already to have it sent to a cytology specialist to look at it and now they say they have to remove it with surgery to biopsy it to know for sure.
