WebMelanocytes located in the epidermis account for 5–10% of all cells. They form epidermal melanin units, which are a dendritic junction of one melanocyte with about 30–40 neighboring keratinocytes. Dermal melanocytes transport mature melanosomes into keratinocytes, which is followed by cell death [2,10,11].
