Below are dermoscopic features commonly associated with the diagnosis "Basal cell carcinoma". The example images have been approved by a panel of experts as representative of each given feature.
For a more in-depth discussion of associated dermoscopic features, please see the Dermoscopedia page for "Basal cell carcinoma".
Discrete, linear to bulbous extensions connected at an off-center base area, forming a leaf-like pattern.
Blue-gray ovoid nests
Confluent or nearly confluent, well-circumscribed, pigmented ovoid areas encompassing at least 10% of the lesion area.
Multiple blue-gray dots and globules (buckshot scatter)
Blue-gray dots are pinpoint blue-gray structures that are often distributed in a buckshot scatter like pattern; Blue-gray globules are well-defined round or oval structures, larger than dots, but smaller than large ovoid nests.
Spoke wheel-like structures / concentric structures
Radial projections that surround a central darker point.
Ulceration / erosion
Shallow erosions that may be covered with congealed blood.
White shiny blotches and strands
White patches or blotches, and linear white areas called strands; can only be seen on polarized dermoscopy.
Arborizing blood vessels
Multiple branching blood vessels in a tree-like pattern. The vessels tend to be bright red and sharply in focus.
