El tumor fibroso solitario (antiguo hemangiopericitoma) es una infrecuente neoplasia de partes blandas cuya localización más frecuente es el retroperitoneo y las extremidades inferiores. Presentamos dos casos de hemangiopericitomas retroperitoneales diagnosticados tras intervención quirúrgica. Realizamos una revisión bibliográfica exponiendo los aspectos clínicos, anatomopatológicos y terapéuticos de estos tumores (AU)

Solitary fibrous tumor (formerly known as hemangiopericytoma) is a rare soft tissue neoplasm, most frequently arising from the retroperitoneum and lower extremities. We present two cases of retroperitoneal solitary fibrous tumors diagnosed after surgical removal. We provide a literature review showing the basic clinical, pathologic and therapeutic features of these tumors (AU)
