Abstract
Entre los tumores hepáticos benignos se encuentra un amplio espectro de lesiones que se comportan de formas muy diversas y que, debido a esto, precisan una estrategia de tratamiento adaptada específicamente a cada uno de ellos. El tumor hepático benigno sólido más frecuente es el hemangioma seguido de la hiperplasia nodular focal, y el tumor quístico más frecuente es el quiste simple. La mayoría de estos tumores son asintomáticos, hallazgos casuales en pruebas de imagen realizadas por otros motivos, y generalmente no precisan tratamiento ni seguimiento. En ocasiones, el diagnóstico diferencial con tumores malignos hepáticos es difícil y esto constituye el principal motivo para la resección quirúrgica, así como la presencia de síntomas o complicaciones. There is a wide range of benign liver tumors that behave in very different ways and require a management strategy specifically tailored to each. The most common benign solid liver tumor is hemangioma followed by focal nodular hyperplasia; the most common cystic tumor is the simple cyst. Most of these tumors are asymptomatic and are discovered as incidental findings on imaging tests performed for other reasons. Usually, no treatment or follow-up is required. The differential diagnosis with malignant liver tumors is sometimes difficult. This difficulty, together with the presence of symptoms or complications, is the main reason for surgical resection.
