Angiosarcoma of the soft tissue is a high-grade sarcoma with a high rate of death and short survival time. A large number of patients, 50% in some series, also had metastasis, and a significant number (20%) had local recurrences. [3, 9, 10]

Older patient age, retroperitoneum location, and larger tumor size are unfavorable prognostic factors. Approximately 66% of retroperitoneal angiosarcomas recur locally in the tumor bed and can recur diffusely throughout the peritoneal cavity (angiosarcomatosis).
