Benign liver tumors are common in general population, can be seen in 9% to 20% of individuals. Some of these tumors have a completely benign natural history and do not need to be resected, while others carry a risk of growth, hemorrhage, or malignant transformation and should be operatively removed. Obtaining a preoperative diagnosis is therefore critical, and this single factor remains the primary challenge in managing patients with benign tumors of the liver. This article gives basic information about hemangioma, liver cell adenoma, focal nodular hyperplasia, and less common lesions that arise from the hepatic epithelial or mesenchymal tissues.
