ARGUELLES SALIDO, E.; CONGREGADO RUIZ, C.B.; MEDINA LOPEZ, R.A.  e  PASCUAL DEL POBIL MORENO, J.L.. Retroperitoneal malignant fibrous histiocytoma. Actas Urol Esp [online]. 2004, vol.28, n.8, pp.624-626. ISSN 0210-4806.

We report a new case of retroperitoneal tumor: a malignant fibrous histiocytoma, in its less agressive histologyc type, the mixoyd variety. This is a recently isolated histologyc presentation from other sarcomas, with a low incidence, non-specific clinic findings and poor prognosis due to its tendency to reappear and to produce metastasis.
