Findings are presented of dynamic examination of 443 patients with soft tissue sarcoma (STS) and 48 patients with aggressive fibromatosis. Relapses were identified in 85 (19.2%) patients with STS and 11 (22.9%) patients with aggressive fibromatosis. Based on ultrasound examination, STS relapses featured: homogenous and non-homogenous solid structure (86.9%), decreased echogenisity (71.2%), and low to moderate vascularization (92.1%). Contrary to prime tumors, they were solitary (63.4%), oval (60.2%), and clearly confined by a pseudocapsule (88.5%) in most cases.
