Lymphangiosarcoma and haemangiosarcoma in a cat.
Ultrastructural findings in a feline ventral abdominal vascular tumour showed lack of basal lamina, few micropinocytotic vesicles and intercellular junctions and a discontinuous endothelial cell layer. A splenic cyst had a continuous basal lamina, numerous micropinocytotic vesicles and intercellular junctions and a continuous endothelial cell layer. These findings were compatible with diagnosis of lymphangiosarcoma (ventral abdomen and metastases) and haemangiosarcoma (splenic cyst).
