The carcinoma of the mucosa of the ethmoid was reported in all domestic animals but specially in cattle and pigs in India. The tumour mass extended from the ethmoid to the nasal cavity and obturated the respiratory tract hence the clinical manifestation reported. Retropharyngeal and parotidal lymphnodes showed by metastases. The tumoral transformation was observed in the cells of the ethmoid mucosa. An early diagnosis could be done by sampling of cells in the nasal mucus. The disease was reproduced by instillation of cellular extracts. Several viruses have been isolated from the tumour tissue. In pigs there was a correlation between the incidence of tumour and the use of aflatoxin contaminated feed. This was an enzootical problem for the herd but neither genetics or microbial factors are determined. Various attempts were made to control the tumour growth.
筛窦黏膜癌在所有家畜中均有报道，但在印度的牛和猪中尤为常见。肿瘤块从筛窦延伸至鼻腔，阻塞呼吸道，因此出现了所报道的临床表现。咽后和腮腺淋巴结出现转移。在筛窦黏膜细胞中观察到肿瘤转化。通过采集鼻黏液中的细胞可进行早期诊断。通过滴注细胞提取物可引发该病。已从肿瘤组织中分离出几种病毒。在猪中，肿瘤发病率与使用受黄曲霉毒素污染的饲料之间存在关联。这是畜群中的一个地方病问题，但尚未确定遗传或微生物因素。人们进行了各种尝试来控制肿瘤生长。
