ABSTRACT In a survey of 3145 feline necropsies at The Animal Medical Centre, eighteen cases of haemangiosarcoma and one case of lymphangiosarcoma were diagnosed. The haemangiosarcomas were primarily located in the spleen (four), liver (six), mesentery (four), mediastinum (three) and the lungs (one). The lymphangiosarcoma was seen in the skin and subcutaneous tissue of the abdominal wall and thighs. The clinical, macroscopic, and microscopic features of these tumours have been described. The most common clinical signs in the case of haemangiosarcoma were due to the rupture of the primary or metastatic neoplasms (70%). Metastases wese observed in 67% of the cases. Three main histological types (1, cavernous; 2, solid; and 3, capillaries separated by stroma) were observed, although mixtures of more than one histological type were seen in any one particular tumour. Rare cases of pulmonary haemangiosarcoma and lymphangiosarcoma in the cat have also been described.
