Kurzfassung auf Englisch: Case summary: A 10-year-old male neutered British Shorthair cat was presented with a 6 month history of lethargy, weight loss and alopecia. Clinical examination revealed widespread alopecia of the ventral abdomen and hindlimbs. The skin in these areas was smooth and shiny and hairs could be easily epilated. Spontaneous pruritus was observed. Cytological examination of superficial impression smears showed a severe Malassezia species dermatitis and pyoderma. Ectoparasites could not be detected and no sign of dermatophytosis was visible in trichograms and Wood’s lamp analysis. Abdominal ultrasound found a focally thickened wall of the large intestine and multiple nodules in the liver. Fine-needle aspirates from lymph nodes, liver and altered colonic wall were consistent with an undifferentiated malignant neoplasia. The cat was euthanased at the owners’ request, owing to potential neoplasia with metastatic spread. At necropsy a metastasising carcinoma of the colonic wall was found, as well as a paraneoplastic alopecia.
Relevance and novel information: Feline paraneoplastic alopecia has been reported in association with pancreatic carcinoma, bile duct carcinoma and hepatocellular carcinoma, as well as with neuroendocrine pancreatic carcinoma and hepatosplenic plasma cell tumour. This is the first reported case of feline paraneoplastic alopecia associated with a colon carcinoma.
