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
