[Retroperitoneal malignant fibrous histiocytoma].
We report a new case of retroperitoneal tumor: a malignant fibrous histiocytoma, in its less aggressive histologic type, the mixoid variety. This is a recently isolated histologic 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.
