Soft tissue sarcomas
Soft tissue sarcomas are tumors of connective tissues. Different soft tissue sarcomas are grouped together within this larger category because they need similar appearances on biopsy and similar clinical behavior within the patient. Subtypes include fibrosarcoma, hemangiopericytoma, liposarcoma, myxosarcoma, and undifferentiated sarcoma, among others.
Soft tissue sarcomas typically grow under the skin. they will feel soft or firm and are usually attached to underlying structures. While the tumor may feel well defined, they’re highly invasive and send microscopic extensions altogether directions. The extent of the tumor is poorly estimated by feel.
Initially, most dogs haven’t any signs associated with the tumor. When signs develop, they’re usually associated with the first tumor instead of spread. because the tumor grows, it can cause difficulty ambulating and/or cause pain. they’ll grow quickly, over the course of a couple of weeks. More commonly they grow slowly over months or years. In advanced cases, the skin overlying the tumor can ulcerate or break open. This leaves dogs vulnerable to pain and infection.
