Hemangiosarcoma

Description:
Hemangiosarcoma is a malignant, rare, rapidly growing, highly invasive variety of cancer. It is a blood-fed sarcoma; that is, blood vessels grow directly into the tumor and it is typically filled with blood. A frequent cause of death is the rupturing of this tumor, causing the victim to rapidly bleed to death.
The term angiosarcoma, when used without modifier, usually refers to hemangiosarcoma. However, glomangiosarcoma (8710/3) and lymphangiosarcoma (9170/3) are distinct conditions. Hemangiosarcomas are commonly associated with toxic exposure to thorium dioxide (Thorotrast), vinyl chloride, and arsenic.
Stewart-Treves syndrome is a form of hemangiosarcoma due to lymphedema, usually following mastectomy and radiotherapy for breast cancer.
