Leaflike areas are brown to blue-gray projections connected radially to a common base, which remind the shape of leaves (Kittler et al., 2016a). Spoke wheel areas are a variant of leaflike areas where radial projections emerge from a dark brown central hub. Sometimes the projections are ill-defined and may resemble concentric structures (clod within a clod). In the absence of pigment network they are highly suggestive of pigmented BCC. (Aimilios Lallas et al., 2015) Histologically, they represent dermal aggregates of pigmented BCC nests at the DEJ and in the papillary dermis (table 6) (Aimilios Lallas et al., 2015).
