PY - 2019 T2 - Fitzpatrick's Dermatology, 9e AB - This chapter discusses melanocytic nevi, defined as benign neoplasms of melanocytes, most of which manifest themselves as cutaneous pigmented lesions. They are characterized by the presence of banal melanocytic cells in nests (defined as three or more melanocytes in direct contact [also known as thèque]), within the epidermis, dermis, or in other tissues. The melanocytic cells forming these nevi are referred to as nevomelanocytes. The term melanocytic hyperplasia is a descriptive term used to indicate increased melanocytes confined to the basal layer of the epidermis in the absence of nest formation.
