Reticular pattern[edit]

A lesion with a reticular pattern has typical pigment network throughout the entire lesion.

Patchy reticular pattern[edit]

A patchy network pattern is a benign pattern composed of islands of pigment network symettrically distributed throughout the entire lesion.

Peripheral reticular with central hyperpigmentation[edit]

In this benign pattern we see typical pigment network at the periphery of lesion with a central dark structureless area.

Peripheral reticular with central hypopigmentation[edit]

In this benign pattern we see typical pigment network at the periphery of a lesion with a central light stuctureles area. This is seen very frequently in compound nevi.

Globular patterns[edit]

Globular pattern[edit]

This is a benign pattern composed of regular globules

Peripheral reticular with central globules[edit]

This is a benign pattern with peripherl reticulation (pigment network) and regular globules in the center

Homogenous pattern[edit]

Homogenous brown pattern[edit]

This benign pattern is frequently seen in congenital nevi

Homogenous tan pattern[edit]

This benign pattern is frequently seen in nevi in redheads

Homogenous blue pattern[edit]

This benign pattern is frequently seen in blue nevu

Pattern with peripheral globules / streaks[edit]

Peripheral rim of globules pattern[edit]

This pattern is currently seen in growing lesions.

Teared globules at the periphery[edit]

This pattern is typically seen in Spitz nevi

Peripheral streaks (starburst pattern)[edit]

This pattern is typically seen in Spitz / Reed nevi

Multicomponent patterns[edit]

Two component pattern[edit]

This pattern can be seen in a kissing nevus (collision of 2 nevi) or in atypical or malignant lesions. We recommend either follow up or excision of these lesions.

Multi component pattern[edit]

A multi component pattern consists of a combination of reticular, globular and homogenous pattern in the same lesion. If the multi component pattern is symmetric throughout the lesion we recommend follow up or excision. It the multicomponent pattern is assymetric, we recommend excision of the lesion.
