case_images: After 2-cm wider excision of the melanoma scar and sentinel lymph node biopsy, the patient had a considerable circular defect in the lumbar area, left of the midline (Figure 1).
case_images: (a) Technique for coverage of lumbar defect using the double perforators-based superior gluteal artery perforator flap. The flap is raised as described in the text and the two dominant perforators are demonstrated emerging between the gluteus maximus muscle fibres. (b) The two dominant perforators are located 6 cm away from each other emerging from parallel rows. (c) The flap is completely freed from its under surface and rotated some 170  clockwise to reach the uppermost part of the defect in a "propeller fashion".

case_images: Careful dissection under 3.5* loupe magnification was performed revealing two dominant perforators emerging between the gluteus maximus muscle fibres (Figure 2(a)). They were located 6 cm away from each other and emerged from parallel rows (Figure 2(b)).
