| Degeneration of the optic pathway has been reported in various animal species including cattle. We experienced a case of bilateral optic tract degeneration characterized by severe gliosis in a Japanese black cattle without any obvious visual defects. To evaluate the significance, pathological nature and pathogenesis of the lesions, we examined the optic pathway in 60 cattle (41 Japanese black, 13 Holstein and 6 crossbreed) with or without ocular abnormalities. None of these animals had optic canal stenosis. Degenerative changes with severe gliosis in the optic pathway, which includes the optic nerve, optic chiasm and optic tract, were only observed in 8 Japanese black cattle with or without ocular abnormalities. Furthermore, strong immunoreactivity of... |

| 38カ月齢のホルスタイン種乳牛において，体全体が左側に傾くという神経症状が進行性に認められた．経過，左側対光反射と左側音響耳介反応の減弱，及び聴性脳幹誘発電位測定検査における左刺激時Ⅲ波-Ⅴ波の遅延所見より，延髄から橋における片側性圧迫性病変を疑った．病理解剖の結果，橋左側に帯黄色脆弱化病巣を認め，病理組織学的検索により，病変は腫瘍であり，迷入組織に由来する可能性があるものの，原発組織は確定できなかった． |

| 10歳の雄の雑種犬が，3週間前から持続する発熱及び元気消失を主訴に帯広畜産大学動物医療センターを受診した．心雑音及び心エコー検査において僧帽弁の疣贅物が確認され，抗生物質等により加療したが，第7病日より心不全の悪化を認め，第10病日に肺水腫により斃死した．病理解剖では，軽度の心拡大及び僧帽弁における多中心性疣贅物が認められた．血液培養検査では，Staphylococcus haemolyticusが検出されたが，疣贅物を用いたPCR検査ではStreptococcus canisと100％一致する塩基配列が得られた．血液培養分離菌はコンタミネーションであった可能性が高く，本症例の心内膜炎はStreptococcus canisによるものと考えられた．血液培養結果と実際の心内膜炎起因菌が異なる場合があることを考慮する必要がある． |

| 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... |

| Humeral chondrosarcoma was found in an 18-year-old male Hokkaido brown bear (Ursus arctos yesoensis). Necropsy revealed a large firm mass under the left superficial pectoral muscle at the axillary region. The mass involved the left shoulder joint and peripheral muscles, and connected to the head of the humerus with osteolysis. Histopathologically, the mass was composed of irregularly shaped myxomatous to cartilaginous tumor lobules. The tumor cell showed moderate nuclear atypia with a relatively high mitotic index, especially in the edges of the myxomatous lobules. The tumor cells were positively immunostained with vimentin and S-100 protein. Based on these findings, the tumors were diagnosed as chondrosarcoma. Metastases were found in the left axillary... |

| 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. |
