The typical network is regularly meshed and composed of lines that are relatively uniform in width and homogenous in color; the lines often become gradually thinner and fainter in pigmentation at the lesion’s periphery:
An example of a typical pigment network clinically and dermoscopically:
On histopathology, the lines of the typical network correspond to pigment in the rete ridges, that are relatively uniform in width and equidistant from each other.
The typical network usually corresponds to the junctional component of a nevus. However, reticulation can also be seen in darkly pigmented normal skin and in heavily pigmented rete ridges as encountered in dermatofibromas, ink spot lentigo or accessory nipples .
