Abstract Background Head and neck cancers HNC are relatively common and often very serious diseases in both dogs and humans. Neoplasms originating in the head and neck region are a heterogeneous group. HNC often has an unfavourable prognosis and the proximity of the tissue structures renders extirpation of tumours with sufficient margins almost incompatible with preservation of functionality. In humans oral malignant melanoma OMM is extremely rare but represents a particular challenge since it is highly aggressive as is the canine counterpart which thus may be of interest as a spontaneous animal model. Methods Canine cases entered in the Danish Veterinary Cancer Registry DVCR from May 15th 2005 through February 29th 2008 were included in this study. Fisher s exact test was used to compare proportions of HNC in dogs and humans as well as proportions of surgically treated cases of OMM and squamous
