Leaf like areas
Leaf-like areas are seen as brown to gray-blue discrete bulbous blobs that often form a pattern shaped like a leaf. They can sometimes appear as tan, broad, and fuzzy streaks at the periphery of a lesion. In the absence of a pigment network, they are highly suggestive of pigmented basal cell carcinomas.
Histopathologically, they represent dermal nodular aggregates of pigmented basal cell carcinoma.
