Hemangiosarcoma of the skin usually appears as a small red or bluish-black lump.

The term angiosarcoma, when used without modifier, usually refers to hemangiosarcoma.

It is suspected that in the skin, hemangiosarcoma is caused by sun exposure.

Visceral hemangiosarcoma is usually fatal even with treatment, and usually within weeks or, at best, months.

This may be in reference to blood (hemangiosarcoma) or lymphatic vessels (lymphangiosarcoma).

Owners of the affected dogs often discover that the dog has hemangiosarcoma only after the dog collapses.

Hemangiosarcoma of the spleen or liver is the most common tumor to cause hemorrhage in the abdomen.

Angiosarcoma and hemangiosarcoma: These are rare forms of cancer that start in the blood vessels of the liver.

Dogs with hemangiosarcoma rarely show clinical signs until the tumor has become very large and has metastasized.

Other cancers that are known to commonly affect Scotties include mast cell sarcoma and hemangiosarcoma.

Hemangiosarcoma is a rapidly growing, highly invasive variety of cancer, occurring almost exclusively in dogs and rarely in cats.

Vascular tumors: angiosarcoma and hemangiosarcoma.

Occasionally, hemangiosarcoma of the skin can be a metastasis from visceral hemangiosarcoma.

Hemangiosarcoma can cause anemia, thrombocytopenia (low platelet count), and disseminated intravascular coagulation (DIC).

When it occurs following mastectomy it is known as Stewart-Treves syndrome (which can be both lymphangiosarcoma and hemangiosarcoma following mastectomy).

Primary liver cancer most commonly manifests as hepatocellular carcinoma and/or cholangiocarcinoma; rarer forms include angiosarcoma and hemangiosarcoma of the liver.

Hemangiosarcoma is quite common in dogs, and more so in certain breeds of dogs including German Shepherds and Golden Retrievers.

The Leonberger Health Foundation, a private nonprofit foundation whose sole mission is to support major researchers who are seeking to identify genetic markers for serious diseases which affect the breed, is currently focusing on osteosarcoma, hemangiosarcoma, and Leonberger Polyneuropathy.

In addition to hip dysplasia, Leonbergers can inherit and/or develop heart problems, Inherited Leonberger Paralysis/Polyneuropathy (ILPN), osteosarcoma, hemangiosarcoma, Osteochondrosis Dissecans, allergies, digestive disorders, cataracts, entropian/ectropian eyelids, progressive retinal atrophy (PRA), perianal fistulas, and thyroid disorders.

A retrospective study published in 1999 by Ware, et al., found a five times greater risk of cardiac hemangiosarcoma in spayed vs. intact female dogs and a 2.4 times greater risk of hemangiosarcoma in neutered dogs as compared to intact males.

Studies of cardiac tumors in dogs showed that there was a 5 times greater risk of hemangiosarcoma, one of the three most common cancers in dogs, in spayed females than intact females and a 2.4 times greater risk of hemangiosarcoma in neutered dogs as compared to intact males.
