Resumen:

Liposarcoma is a malignant tumor of mesenchymal origin, which represents the most frequent variety of soft tissue sarcomas. However, the incidence of these tumors in adult oncological pathology is less than 1%. Of that percentage, only between 10% and 15% are located in the retroperitoneum. We present the clinical case of a patient with incidental diagnosis of a retroperitoneal tumor, and suspected imaging of liposarcoma with anatomopathological confirmation of myxoid variety. The complete macroscopic excresis of the lesion and external adjuvant radiotherapy were performed. A brief summary of the current management of the aforementioned pathology is also presented.


El liposarcoma es un tumor maligno de origen mesenquimático, que representa la variedad más frecuente de sarcomas de partes blandas. No obstante, la incidencia de estos tumores en la patología oncológica del adulto es menor al 1%. De ese porcentaje, tan solo entre un 10% a 15% se localizan en el retroperitoneo. Se presenta el caso clínico de un paciente con diagnóstico incidental de un tumor retroperitoneal, y sospecha imagenológica de liposarcoma con confirmación anatomopatológica de variedad mixoide. Se realizó la excéresis macroscópica completa de la lesión y radioterapia externa adyuvante.Se presenta además un breve resumen del manejo actual de la citada patología.
