“…-Pleomorphic, with many different types of cells. In our case there was an association of several histological subtypes, with each recurrence being more aggressive histologically, although there were no signs of distant metastases (3,4). The histologic diagnosis is based on the presence of fatty tissue cells and immunohistochemical techniques like S-100, desmin, CD117 and cytokeratins, markers of different types of cells (5), and the determination of changes in the region 12q13-15 that produce MDM2 and CDK4 gene mutations, involved in the malignancy of the different subtypes of cells.…”

“…CT can clearly demonstrate the characteristics of the mass, the localisation of tumours and the relation to adjacent organs and vessels. It is also used to detect pulmonary, bone or hepatic metastases and local recurrence in patients who have already been resected, 12 which is helpful in making precise surgical plans.…”

“…En cuanto a la supervivencia, oscila alrededor del 40% tras una resección completa y solamente del 5% cuando no puede resecarse todo el tumor, lo cual ocurre en un porcentaje de alrededor del 25 de los casos [4,26]. parece haber acuerdo en su utilización de forma paliativa en tumores no operables o en caso de completa ya que, a pesar de que los tumores mesodérmicos son radiorresistentes, el liposarcoma es el más radiosensible [1,10].…”

“…Algunos órganos como los riñones, uréteres y suprarrenales están dentro de Los sarcomas de tejidos blandos son tumores poco frecuentes y representan el 1% de s tumores sólidos del adulto. Sólo entre el 10 y el 20% de estos tumores se localizan en el retroperitoneo [3,4]. El liposarcoma es la variedad histopatológica más frecuente de los tumores retroperitoneales, que por sí mismos suponen 2% de todas las neoplasias del En general, los liposarcomas se originan de tejidos blandos profundos del organismo, principalmente en pelvis, retroperitoneo, y mesenterio [7,8].…”
