Fibrosarcoma
A fibrosarcoma or fibroblastic sarcoma is a malignant tumor in animals and humans that arises from connective tissue cells and is characterized by immature, proliferating fibroblasts or anaplastic spindle cells .
Fibrosarcoma is a very rare tumor that occurs in humans in all age groups, and can even be congenital. Therefore, a distinction is made between congenital and infantile species in children under five years of age and the adult form. It occurs most frequently in men over the age of four. Therapy consists of extensive surgical removal of the tumor followed by radio or chemotherapy. The prognosis is usually unfavorable.
In 1943, fibrosarcoma was differentiated from the group of osteosarcomas , because the 5-year survival rate here, at 31 percent, was significantly better than that of osteosarcomas.
The Feline fibrosarcoma is with about 40 percent of the time the second most common skin cancer form in cats . Here, it is assumed that a relationship of tumor formation with injections (injection-associated fibrosarcoma) is. In these cases, the likelihood of metastasis forming is significantly higher.
