Tumours of the oropharynx of domestic animals are common in most parts of the world, but squamous cell carcinoma of the upper alimentary tract shows differences in prevalence in different geographical areas and occurs at different sites in the various species. Oral tumours of the melanogenic system are more common in dogs than in man. The following main histological categories, which broadly correspond to those used in the classification of tumours of man, are described: papilloma; squamous cell carcinoma; salivary gland tumours; malignant melanoma; tumours of soft (mesenchymal) tissues; tumours of the facial bones; tumours of haematopoietic and related tissues; and odontogenic tumours and jaw cysts. Papilloma, squamous cell carcinoma, malignant melanoma, fibroma, and fibrosarcoma account for about 80% of the tumours that occur in the upper alimentary tract of domestic animals.
家畜口咽肿瘤在世界大部分地区都很常见，但上消化道鳞状细胞癌在不同地理区域的患病率存在差异，且在不同物种中的发病部位也不同。黑色素生成系统的口腔肿瘤在犬类中比在人类中更常见。以下是主要的组织学类别，大致与人类肿瘤分类中使用的类别相对应：乳头状瘤；鳞状细胞癌；唾液腺肿瘤；恶性黑色素瘤；软组织（间充质）肿瘤；面骨肿瘤；造血及相关组织肿瘤；牙源性肿瘤和颌骨囊肿。乳头状瘤、鳞状细胞癌、恶性黑色素瘤、纤维瘤和纤维肉瘤约占家畜上消化道发生肿瘤的80%。
