This melanoma is characterized by numerous irregular streaks (arrows) throughout the lesion

|
Note several irregular streaks (arrows) at the upper left part of this melanoma
|
|
|
This melanoma is characterized by streaks (arrows) unevenly distributed along the periphery
|
|
|
The radial arrangement of streaks along the periphery of this lesion is virtually diagnostic for Reed nevus
|
|
|
Streaks are presumably formed by a particular three-dimensional arrangement of heavily pigmented nests of melanocytes (circle) as exhibited in this melanoma. Three-dimensional reconstructions, however, would be necessary in order to confirm this assumption. The dermoscopic-pathologic correlation is aggravated by the fact that dermoscopic features and their underlying histopathologic structures are present in two different planes, namely, the horizontal and vertical ones
