Benign nevus pattern
Reticular patterns[edit | edit source]
Reticular pattern[edit | edit source]
A lesion with a reticular pattern has typical pigment network throughout the entire lesion.
Patchy reticular pattern[edit | edit source]
A patchy network pattern is a benign pattern composed of islands of pigment network symmetrically distributed throughout the entire lesion.
Peripheral reticular with central hyperpigmentation[edit | edit source]
In this benign pattern we see typical pigment network at the periphery of the lesion with a central dark structureless area.
Peripheral reticular with central hypopigmentation[edit | edit source]
In this benign pattern we see typical pigment network at the periphery of the lesion with a central light structureless area. This is seen very frequently in compound nevi.
Globular patterns[edit | edit source]
Globular pattern[edit | edit source]
This is a benign pattern composed of regular globules
Cobblestone pattern[edit | edit source]
This is a variation of the globular pattern in which the globules are larger and more angulated, resembling a cobblestone
Peripheral reticular with central globules[edit | edit source]
This is a benign pattern with peripheral reticulation (pigmented network) and regular globules in the center
Homogenous patterns[edit | edit source]
Homogenous brown pattern[edit | edit source]
This benign pattern is frequently seen in congenital nevi
Homogenous tan pattern[edit | edit source]
This benign pattern is frequently seen in nevi in redheads
Homogenous blue pattern[edit | edit source]
This benign pattern is frequently seen in blue nevi
Patterns with peripheral globules / streaks[edit | edit source]
Peripheral rim of globules pattern[edit | edit source]
This pattern is currently seen in growing lesions.
Teared globules at the periphery[edit | edit source]
This pattern is typically seen in Spitz nevi
Peripheral streaks (starburst pattern)[edit | edit source]
This pattern is typically seen in Spitz / Reed nevi
Multicomponent patterns[edit | edit source]
Two component pattern[edit | edit source]
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 | edit source]
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. If the multicomponent pattern is assymetric, we recommend excision of the lesion.
