This quiz will test your knowledge of benign melanocytic naevi.
Melanocytic naevi may be congenital or acquired. Melanocytes are normally separated from each other along the basal layer of the epidermis, but in naevi they form nests in contact with each other within the epidermis and/or dermis. They may be found on any cutaneous or mucosal site. Groups of benign naevus cells are sometimes also found in lymph nodes, where they are known as ‘rests’.
