Location: Connective tissue (sub)cutaneous
Behavior: Grows slowly in nearby tissues, rarely metastasizes
Diagnostics: Cytology, histology, radiography
Treatment: Surgery, (chemotherapy, radiotherapy)

These are generally slow growing and non-painful masses. Depending on the localization of the tumor and how invasive the tumor is, local symptoms will occur (e.g. tumor that penetrates the bone or complicates the folding of the toes will cause limping). Satellite injuries occur regularly. This is because fibrosarcomas choose the path of least resistance when spreading. When there is tension in the skin, the tumor spreads away from this tension.
