Below are dermoscopic features commonly associated with the diagnosis “Overview of benign nevi patterns”. The example images have been approved by a panel of experts as representative of each given feature.
For a more in-depth discussion of associated features, please see the Dermoscopedia page for “Overview of benign nevi patterns”.
Diffuse reticular network[edit]
A pigment network has a grid-like pattern consisting of interconnecting pigmented lines surrounding hypopigmented holes. A typical network has minimal variability in the color, thickness, and spacing of the lines and symmetrically distributed throughout the lesion.[1]
Patchy reticular network[edit]
Islands of pigment network symmetrically distributed throughout the entire lesion.[2]
Peripheral reticular network with central hypopigmentation[edit]
Peripheral reticular network with central hyperpigmentation[edit]
Peripheral reticular network with central globules[edit]
Homogeneous (tan, brown, blue, or pink)[edit]
Central network with evenly distributed peripheral globules[edit]
Globular pattern[edit]
Regular globules have minimal variability in their color, size and shape.[3]
Two-component pattern[edit]
Symmetric multi-component pattern[edit]
A multi-component pattern consists of a combination of reticular, globular and homogenous pattern in the same lesion.[4]
