Optimising size and depth of punch grafts in autologous transplantation of vitiligo and piebaldism: a randomised controlled trial.

Background: To date, autologous punch grafting appears to be the easiest and least expensive surgical technique for stable vitiligo and piebaldism. Punch grafting is available worldwide, with no need for specialised instruments. However, no reliable data on efficacy and safety of different punch depths and punch sizes are available.

The antibody response against MART-1 differs in patients with melanoma-associated leucoderma and vitiligo.

Patients with melanoma may develop skin depigmentation spontaneously or following therapy, referred to as melanoma-associated leucoderma (MAL). As clinical presentation of MAL may precede primary/metastatic melanoma detection, recognition of MAL is important to prevent its misdiagnosis as vitiligo and the subsequent application of immunosuppressive treatment. To reveal the immunity involved in MAL development, we investigated the presence of antibody and T-cell immune responses directed against the melanocyte-differentiation-antigens MART-1 (Melan-A), tyrosinase and gp100 in patients with MAL, as compared to patients with vitiligo.
