SUMMARY A tumor mass with hemorrhage was observed in the liver of a six-month-old barrow, and histopathology
revealed proliferation of spindle or pleomorphic cells forming various sized vasculature containing blood
as well as silver-stained networks of the vascular basement membrane. The proliferated cells were positive
for vimentin and factor VIII by immunostain and the case was diagnosed as hemangiosarcoma. --------------------J. Jpn. Vet. Med. Assoc., 52, 253〜255(1999) |
