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]
