A case of feline paraneoplastic alopecia with secondary Malossezia‐associated dermatitis
1998
Godfrey, D. R.
A 13‐year‐old neutered female domestic shorthaired cat had progressive ventral abdominal alopecia attributed initially to hyperthyroidism. Corrective treatment by unilateral thyroidectomy did not, however, resolve the dermatosis and the alopecia progressed to involve the whole ventral trunk, the lower limbs and the head. Pruritus of the lower limbs was a prominent feature and was associated with the finding of Malassezia on cytology; Malassezia‐associated dermatitis was diagnosed. Resolution of pruritus was seen after treatment with oral ketoconazole and a cleansing shampoo to eliminate the yeast, but severe polyphagia, small intestinal diarrhoea and polydipsia developed subsequently and the cat was euthanased. Necropsy revealed an exocrine pancreatic adenocarcinoma with hepatic metastases. The pancreatic, hepatic and dermatologlcal lesions were found to be typical of feline paraneoplastic alopecia (FPA). Malassezia‐associated dermatitis can be associated with pruritus in cats with FPA.
