Diffuse reticular network

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

Islands of pigment network symmetrically distributed throughout the entire lesion.[2]

Peripheral reticular network with central hypopigmentation

Peripheral reticular network with central hyperpigmentation

Peripheral reticular network with central globules

Homogeneous (tan, brown, blue, or pink)

Central network with evenly distributed peripheral globules

Globular pattern

Regular globules have minimal variability in their color, size and shape.[3]

Two-component pattern

Symmetric multi-component pattern

A multi-component pattern consists of a combination of reticular, globular and homogenous pattern in the same lesion.[4]
