Massive hepatoma treated with curative-intent liver lobectomy in a standard poodle dog

A 12-year-old neutered male standard poodle was seen at a veterinary clinic for a complete oral health assessment and treatment. A routine blood biochemistry revealed a marked hepatic enzymopathy, with gamma-glutamyltransferase being the most severely elevated enzyme. Liver lobectomy was performed to remove a hepatic tumor visualized on abdominal ultrasound examination. Despite concerns for a cholestatic disorder or biliary neoplasia, histopathology of the resected mass confirmed a massive hepatoma from the left lateral liver lobe.
