==Haemangiosarcoma==

[[Haemangiosarcoma|Haemangiosarcomas]] are a highly malignant tumour of vascular endothelial origin (cf [[Haemangioma|Haemangiomas]] which are more benign and generally affect other vascular tissue such as cutaneous vascular tissues). They commonly affect dogs and the most frequently affected areas are the spleen, pericardium, right atrium, [[Liver - Anatomy & Physiology|liver]] and muscle.  Cats are less frequently affected; the most common sites for feline haemangiosarcomas are the liver, spleen and mesentry. Metastasis occurs via the haematogenous route or via splenic capsule rupture and transabdominal spread.  Metastatic sites include, lungs, liver, omentum and diaphragm. Surgery is the treatment of choice but even with this survival time remains very short.
