| 5歳5カ月齢のホルスタイン種雌牛が，発熱，食欲不振及び胎盤停滞を呈した．悪露排出及び子宮の腫脹は治療で改善がみられなかった．体表リンパ節の腫大はみられなかったが，直腸検査で子宮の硬結を認めたため，牛白血病を疑った．病理解剖では腹腔内リンパ節の腫大，胃漿膜面の腫瘤形成及び子宮壁の肥厚が認められた．また，組織所見ではこれら組織へのリンパ球様腫瘍細胞の浸潤が認められた．腫瘍細胞はB細胞マーカー陽性であった．牛白血病ウイルス（BLV）抗体は陰性であったが，末梢血のBLVプロウイルス検査では陽性が確認され，本症例におけるBLVの関与が示唆された． A 5-year-5-month old Holstein cow was presented with fever, anorexia, and retained placenta. Postnatal vaginal discharge and enlargement of the uterus did not improve after treatment. Although the superficial lymph nodes were not enlarged, enzootic bovine leukosis was suspected because of the enlarged and indurated uterus. An autopsy revealed enlargement of most abdominal lymph nodes, tumor mass formation on the omasum and abomasum, and thickening of the uterine wall. Histologically, there... |

| An 11-year-old Holstein-Friesian cow exhibited anorexia and jaundice. A large mass was found in the liver during necropsy. Macroscopically, the mass was composed of dark red multilobular tissue and a centrally located abscess, which was connected to the hepatic duct. Histologically, the mass consisted of proliferation of small neoplastic cells and was demarcated from the hepatic parenchyma by a thick region of granulation tissue. The neoplastic cells were predominantly arranged in solid sheets, but they also formed blood-filled cancellous structures, and proliferating foci were seen around blood vessels. Periodic acid-Schiff reaction demonstrated that a fine basement membrane-like structure surrounded the neoplastic cells. Immunohistochemically, the... |

| 5歳6カ月齢のホルスタイン種乳牛が鼻出血，眼球突出および黒色便を呈したため，地方病性牛白血病を疑った．し かし，生前の臨床検査では牛白血病の確定診断はできず，病理組織学的検査により鼻腔内骨肉腫と診断された．本症例では，明瞭な呼吸器症状や顔面の変形といった鼻腔内腫瘍を疑わせる所見が乏しく，生前診断が困難であった． Enzootic bovine leukosis was suspected in a Holstein cow aged 5-years and 6-months, as it displayed symptoms of epistaxis, proptosis, and melena. However, clinicopathological findings failed to confirm a diagnosis of bovine leukosis, and histopathological findings revealed a nasal osteosarcoma. As the case lacked typical findings of nasal tumor such as sneezing and facial deformity, a nasal tumor diagnosis would have been difficult. |
