| Abstract: | Benign solid liver tumors are a heterogeneous group of lesions (adenoma, focal nodular hyperplasia, hemangioma, etc.) with highly varied epidemiological characteristics. Advances in diagnostic methods have improved preoperative diagnosis. Magnetic resonance imaging has become the key test, but there is still a percentage of cases in which definitive preoperative diagnosis is not feasible. The most frequent symptom is abdominal pain, although patients are frequently asymptomatic. Surgery is indicated when diagnosis is uncertain or there are complications (rupture, hemorrhage, etc.). Because of the risk of malignant transformation, adenomas should always be resected. Morbidity and mortality after resection of these tumors is very low since excision is limited, performed in young people without concomitant disease, and in healthy liver. |
