Haemangioma

• benign tumour of dogs
• may grow to considerable size

- the size of the lesion giving rise to clinical signs is compounded by haemorrhage from and into the tumour

- thus, a large mass of apple size may be found protruding from the spleen and adherent to the omentum

• on section, it is largely blood clot
• responds well to surgery

- therefore it must be distinguished from haemangiosarcoma
