Two cases of male breast cancer are presented. The patients underwent a modified radical mastectomy with immediate closure of the defect using a triple L-shaped transposition flap. We briefly recall the behaviour of these tumors and the applied surgical principles to define better the value of this plastic procedure. A variety of surgical plastic techniques are described and compared. The triple L-shaped Limberg flap, very well adapted to the treatment of male breast cancer, is described in detail. The results are gratifying both from the plastic and cancerologic view-point.
