Histologic patterns of recurrent nevus phenomenon. In the histologic patterns types 1and 2, there is effacement of the retiform epidermis with junctional (a) and compound melanocytic hyperplasia (b), respectively. Dermal scar accompanies both biopsies. This is in contrast to types 3 and 4, where there is retiform epidermal hyperplasia, associated with junctional (c) and compound melanocytic hyperplasia (d), and dermal scar.
