Soft Tissue Sarcomas in Dogs

Jul 26, 2018

Soft tissue sarcomas (STS) make up a large category of tumors that arise from connective tissue. This category includes tumors of fibrous tissue, fat, smooth muscle, nerves, and lymphatic vessels. The diagnosis of soft tissue sarcoma includes fibrosarcomas, malignant peripheral nerve sheath tumors, histiocytomas, myxosarcomas, liposarcomas, lymphangiosarcomas, and undifferentiated sarcomas. STS comprise ~15% of all skin/subcutaneous (under the skin) tumors. These tumors are typically very invasive to the surrounding tissue but generally have a low risk of spreading (metastasis).
