ABSTRACT
Introducción: De los tumores de retroperitóneo, el liposarcoma es considerado de crecimiento rápido y gran porcentaje de recurrencia, los autores lo consideran una patología inusual. Los sarcomas retroperitoneales son poco comunes constituyen el 10 a 15% de todos los sarcomas y su incidencia anual está estimada en 2.7 casos por millón de habitantes. Se decide realizar el presente estudio debido a ser patología inusual, siendo el objetivo principal la importancia del manejo quirúrgico de este tipo de tumores gigantes retroperitoneales. Métodos: Estudio descriptivo, retrospectivo, longitudinal, realizado en el Hospital Abel Gilbert Pontón desde enero 2013 a diciembre 2017. Se realiza revisión de historias clínica de todos los pacientes que acudieron a consulta externa presentando masa abdominal. Se seleccionan aquellos con diagnóstico anatomopatológico de liposarcoma retroperitoneal gigante, con datos completos en su historial y con mínimo 2 controles por consulta externa. Resultados: la muestra estudiada fue de 4 pacientes intervenidos quirúrgicamente entre 40 y 65 años. Tumores entre 45 a 70 cm, 1 caso con compromiso a órganos vecinos. No se reportaron complicaciones. Recibieron el alta en promedio a las 2 semanas de operados Conclusión: La serie de casos revisada evidencia que el manejo adecuado de este tipo de patologías, es multidisciplinario, siendo la piedra angular el tratamiento quirúrgico.
