A new approach using a numerical diagnostic criterion for vitiligo diagnosis with HMB-45 and Melan-A staining.

This study aims to investigate the usefulness of the Melan-A and homatropine methyl bromide-45 (HMB-45) markers in identifying melanocytes and to evaluate cut-off values for the diagnosis of vitiligo. We also aim to identify the role of remaining melanocytes when using HMB-45. We counted and confirmed melanocytes and melanin in the samples using a high-magnification microscope. The Melan-A, HMB-45, and Fontana-Masson staining methods were...
