Repigmentation after autologous miniature punch grafting in segmental vitiligo in North Indian patients

Segmental vitiligo is rather refractory to medical treatment. The paucity of literature on the results of autologous miniature punch grafting in segmental vitiligo in dark-skinned patients led us to conduct such a study in 15 dark-skinned patients of North Indian origin to observe the repigmentation response to this technique at different sites. The age range was 16-42 years (mean 23.08 years). There were four males and eleven females (M:F ratio being 1:2.75) who had the disease for 3-15 years. After autologous miniature punch grafting, a remarkable repigmentation was obtained in 12 (80%) cases with 90% to 100% improvement. About 40-60% repigmentation was observed within 3-6 months in the majority (66.6%) of cases and near total to total repigmentation was observed within 2 years. The maximum pigment spread was observed over the face (cheeks) and neck, and the minimum pigment spread was observed over the left arm and right upper eyelid. Complications were minimal. The present study demonstrates that autologous miniature punch grafting is a safe and easy technique, that produces good cosmetic results in the unsightly depigmenting lesions of segmental vitiligo, especially on the face and exposed areas, even in dark-skinned races if patients are selected carefully. This can be of great benefit to patients who are psychologically disturbed by their disease.
