Background: Primary hepatobiliary tumors are rare in dogs and cats. Studies suggest a prevalence of 0.6% in dogs and 2.9% in cats from all occurring tumors. Neoplasia in these tissues can have hepatocellular and bile ducts origin or even be sarcomas or neuroendocrine tumors. Its clinical signs are nonspecific and the diagnosis is most often tardy or even done during necropsy. A case of cholangiocellular carcinoma and glomerulonephritis in a cat is reported, addressing its clinical aspects and emphasizing the importance of an early diagnosis.Case: A mixed breed, 12-year-old neutered cat was admitted in the Veterinary Teaching Hospital of the Federal University of Rio Grande do Sul treated previously without obvious improvement. Jaundice, severe dehydration, excessive salivation, low body condition (score three out of nine), abdominal discomfort, and lethargy were evident on physical examination. Blood tests showed neutrophilic leukocytosis, lymphopenia, and increased serum levels of both alanine aminotransferase and alkaline phosphatase enzymes.
