Abstract
Tumors 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 various species. Oral tumors of the melanogenic system are more common in dogs than in man. The following histological categories, which broadly correspond to those used in the classification of tumors of man, are described: papilloma, squamous cell carcinoma, salivary gland tumors, malignant melanoma, tumors of soft (mesenchymal) tissues, tumors of the facial bones, tumors of hematopoietic and related tissues and odontogenic tumors and jaw cysts. Papilloma, squamous cell carcinoma, malignant melanoma, fibroma and fibrosarcoma account for about 80% of the tumors that occur in the upper alimentary tract of domestic animals.
