Hepatoma

Contributor(s): Susan North

Introduction

  • Primary hepatic tumors are rare in cats, accounting for approximately 1% of feline tumors.
  • Signs: large cranial abdominal mass, may be associated with gradual weight loss due to inappetence, +/- vomiting Vomiting.
  • Paraneoplastic hypoglycemia has been documented.
  • Diagnosis: diagnostic imaging, exploratory laparotomy Laparotomy: midline, biopsy and histopathology.
  • Treatment: liver lobectomy Lobectomy: liver.
  • Prognosis: good.

Pathogenesis

Etiology

  • Unknown.
  • Benign tumor of hepatocytes.

Pathophysiology

  • Affects one liver lobe.
  • Degree and significance of clinical signs depends on lobe affected and size of tumor causing compression as a space occupying lesion.
  • Secondary effects may be seen due to presence of a large space-occupying mass within one liver lobe, eg compression of bile duct/gall bladder, compression on stomach.

Timecourse

  • Recognized late.
  • Often these tumors are large before signs seen, therefore may have been slow growing for many months.
