A tumor was removed from the nose of a 4-year-old Holstein. Hemangiosarcoma was diagnosed on histologic examination. Redevelopment of the tumor necessitated a second surgery. Routine CBC and serum biochemical analysis were normal. Clinical signs of metastasis were not reported by the owner during the next 13 months before the cow was sold for slaughter.
