Leaf-like structures[edit]

Discrete, linear to bulbous extensions connected at an off-center base area, forming a leaf-like pattern.[1]

Blue-gray ovoid nests[edit]

Confluent or nearly confluent, well-circumscribed, pigmented ovoid areas encompassing at least 10% of the lesion area.[2]

Multiple blue-gray dots and globules (buckshot scatter)[edit]

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.[3]

Spoke wheel-like structures / concentric structures[edit]

Radial projections that surround a central darker point.[4]

Ulceration / erosion[edit]

Shallow erosions that may be covered with congealed blood.[5]

White shiny blotches and strands[edit]

White patches or blotches, and linear white areas called strands; can only be seen on polarized dermoscopy.[6]

Arborizing blood vessels[edit]

Multiple branching blood vessels in a tree-like pattern. The vessels tend to be bright red and sharply in focus.[7]

Short fine telangiectasias (superficial BCC)[edit]
