The use of cross-leg flap in malignancy: realization of a potential complication.

We present a case of recurrent myxoid fibrosarcoma presumed to have spread to the contralateral leg by means of cross-leg flap procedure. In the era of free flap transfer, musculocutaneous flaps and the recent cross-leg musculocutaneous flap, the cross-leg flap remains a valuable technique for the reconstructive plastic surgeon. However, it should not be considered in reconstruction after resection of a malignant tumor.
