[Renal liposarcoma. Report of one case and bibliographic review].
OBJECTIVE
To report a new case of well-differentiated renal liposarcoma, and to describe its clinical features, diagnosis, treatment, and differences with other mesenchymal tumors of the retroperitoneum.


METHODS
We perform a clinical review of renal mesenchymal tumors, especially liposarcomas. We report one case of well-differentiated renal liposarcoma in a 52-year-old female, and review current lines of treatment and follow-up.


CONCLUSIONS
The well-differentiated renal liposarcoma is a very unfrequent mesenchymal tumor, for which it is necessary to know exactly its origin in the renal parenchyma. The treatment of choice is complete tumor exeresis; close follow-up should be exercised because even though it does not metastasize, local recurrences appear in 30% of the cases.
