Retroperitoneal liposarcoma presenting with bilateral leg lymphedema--case report.

The case of a 54-year-old man with a large right retroperitoneal liposarcoma presenting with bilateral leg lymphedema, is reported. Total excision of the tumor resulted in marked reduction of the edema in both legs persisting for four years. Follow-up lymphographies demonstrated lymphatic drainage dysfunction on both sides; nevertheless, the edema did not recur. Based on these findings, a non-compressive hypothesis concerning the evolution of lymphedema in this case is postulated.
