Benign liver tumours are commonly identified and usually asymptomatic, however, upon discovery, may pose a challenge in characterization and management. Cavernous haemangioma is the most common benign liver tumour. It may present in various sizes and numbers and if significantly large can cause clinical symptoms due to thrombosis, rupture, and haemorrhage. Among the benign tumours of hepatocellular origin, hepatocellular adenoma and focal nodular hyperplasia are frequently seen in young females, with the former having variants which carry the potential for malignant transformation. Biliary hamartomas and focal fatty lesions are often encountered intraoperatively and may be misconstrued as malignant deposits. Due to their byzantine clinical behaviour, a thorough knowledge of the vast array of benign liver tumours and their aetiopathogenesis is sine qua non for management.
