Melanoma in situ on the back with an asymmetric distribution of colors and structures that can be clearly appreciated on the dermoscopic image

|
Melanoma in situ on the leg characterized predominantly by a combination of blue areas and whitish areas (so-called blue-whitish areas) virtually indistinguishable from a blue-whitish veil

Melanoma in situ of the face, also called lentigo maligna, exhibiting annular-granular structures (black arrows) and rhomboidal structures (white arrow)

This is a stereotypical example of early invasive melanoma on the back displaying basically all the relevant melanoma-specific criteria
|
|
|
Early invasive melanoma on the neck with pronounced diffuse hyperpigmentation. Thus the dermoscopic melanoma-specific criteria, such as atypical pigment network, irregular streaks and irregular dots/globules, are rather difficult to detect.

This melanoma of intermediate thickness on the chest reveals a blue-whitish veil that in association with irregular streaks and irregular dots/globules is virtually diagnostic
|
|
|
This thick melanoma on the leg is characterized by a bluish nodule covered by a hyperpigmented scale-crust
