Cutaneous Paraneoplastic Syndromes in Dogs and Cats: A Review of the Literature

Cutaneous paraneoplastic syndromes in dogs and cats were noncancerous skin disorders linked to internal malignancies, aiding in the detection and treatment of underlying cancers. While over 30 such disorders were identified in humans, only a few were described in veterinary medicine, possibly due to lower incidence or lack of recognition. Recognized veterinary paraneoplastic dermatoses included feline paraneoplastic alopecia, feline thymoma-associated exfoliative dermatitis, and others, often associated with specific tumor types. The causes of these syndromes remained largely unknown in both humans and animals.
