| 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. |
