ABSTRACT
Lymphoma involving the skin in dogs and cats is relatively uncommon. Cutaneous lymphoma accounts for 3%-8% of all cases of lymphosarcoma reported in dogs.163,164 Reliable information on occurrence rates in cats is unavailable, but in general, it is safe to conclude that cutaneous lymphoma occurs less frequently in cats than in dogs. This form of lymphoma tends to occur in older animals with a mean age of onset in dogs of 9.5 years and 11 years in cats.165-167 In several studies of cats with this form of lymphoma, all cats tested were FeLV test negative.165-169 Cutaneous lymphoma can occur as the primary form, or it may disseminate to or from other areas.
