Autologous miniature skin punch grafting in vitiligo

Forty-five sites of stable vitiligo in 32 patients refractory to medical treatment were subjected to autologous miniature skin punch grafting. Main instruments used were skin biopsy punches 1-3 mm in diameter. Donor sites selected were either gluteal region or extensor aspect of the thigh which were not affected by the disease in the past. Most of the grafts changed from brown to black and upper scales desquamated within 10-15 days. Uniform perigraft pigmentation was observed by 1-1½ months and 90% area was covered within 3-4 months. The cases were followed up for six months. Fair to excellent results were observed in 87.5% of the cases.
