Dermal gland ducts

Melanocytes are located in the basal layer of the epidermis (Figure 1.1). They can be found in the external root sheath and hair matrix of hair follicles, in the sweat gland ducts, and in sebaceous glands. Melanocytes have dendritic processes that either extend between adjacent keratinocytes or run parallel to the dermal surface.
