A prototypic histologic pattern of RN was described as consisting of a junctional melanocytic component with varying degrees of pigmentation overlying fibrous scar tissue and deep, residual, monomorphous nevus cells lacking mitotic figures (2); this pattern would later be termed trizonal. (3) Several of the earlier studies involving RN disagree with regard to junctional melanocytic activity, a term used to describe excessive pigmentation of epidermal cells and increased prominence of melanocytes in the basal layer, without implying increased mitotic figures (which were not observed).
