Abstract

Background: Low grade fibromyxoid sarcoma or tumor Evans is a variety of soft tissue sarcoma that represents 1% of all malignancies. More common in limbs and trunk (50%), we present 3 new cases of retroperitoneal reviewing their characteristics and performing a literature review.

Clinical case: In the retroperitoneal location highlights the poor specificity of clinical symptoms, demonstrating, according to their growth and size, as an abdominal tumor, usually painless, or by compression and/or invasion of nearby structures. In cases that present the most important finding was the presence of a palpable abdominal tumor without other symptoms despite remarkable infiltration of other organs that should be included in surgical resection.

Conclusions: We emphasize the difficulty of correct diagnosis preoperatively because preoperative studies are inconclusive and only the histological and immuno-histo-typing chemistry allow precise identification.

Antecedentes: el sarcoma fibromixoide de bajo grado o tumor de Evans es una variedad de sarcoma de partes blandas que representa el 1% de todos los tumores malignos. Más frecuente en extremidades y tronco (50%), presentamos tres nuevos casos de localización retroperitoneal. Se revisan sus características y se realiza actualización bibliográfica. Casos clínicos: en su localización retroperitoneal destaca lo inespecífico de su sintomatología clínica, se manifiesta en función de su crecimiento y tamaño, como una tumoración abdominal, habitualmente indolora, o por la compresión y/o invasión de estructuras próximas. Los casos presentados se manifestaron, por la presencia de tumoración abdominal, sin otra sintomatología; a pesar de infiltrar a otros órganos. Conclusiones: el diagnóstico preoperatorio es difícil, y debe tenerse la presunción clínica para solicitar el estudio histológico, con tipificación inmuno-histo-química para su dentificación precisa.

Keywords: Low-grade fibromyxoid sarcoma; retroperitoneal tumor; sarcoma de tejidos blandos; sarcoma fibromixoide de bajo grado; soft tissue sarcoma.
