A 15-year-old spayed female domestic shorthair cat presented with alopecia associated with hepatocellular carcinoma. Clinical signs, which had commenced 6 months previously, included loss of appetite, loss of weight, and depression. As reported by the owner, the cat developed alopecia a week before referral. The hair loss was localized to the ventral aspect of the thorax and abdomen, medial aspect of front and hind limbs, and ventral aspect of the tail, and was associated with histological features consistent with paraneoplastic alopecia. At necropsy, multiple hepatic nodules were observed, and subsequent histopathological investigation showed cords and sheets of hepatocyte-like neoplastic cells positive for the hepatocyte marker (Hep Par 1), thereby demonstrating the hepatocellular origin of the tumour, which was diagnosed as a hepatocellular carcinoma. This is the first report of feline paraneoplastic alopecia associated with hepatocellular carcinoma confirmed by the Hep Par 1 marker.
