With hemangiosarcoma, the pericardium fills up with blood due to rupture of the tumor. When the tumor occurs in the skin, a mass or lump can usually be felt in or under the skin. The mass may become ulcerated and bleed. When the tumor occurs in a bone, it can cause pain and discomfort.
Hemothorax is defined as blood within the chest cavity. The most common cause of hemothorax in dogs is chest trauma, although tumors within the thorax (chest cavity) can also result in a hemothorax if they rupture, slowly bleed or invade into a blood vessel causing blood to accumulate in the thorax.
