Pigmented BCCs:

 

Arborising telangiectasia:

These are small branching blood vessels in a 'tree-like' pattern.

 

 

 

 

 

 

 

 

 

 

Blue-grey ovoid nests:

These are pigmented tumour islands of BCC and look like blue 'blobs'.

 

 

 

 

 

 

 

 

 

 

 

 

Blue-grey globules:

These are small islands of pigmented tumour cells.

 

 

 

 

 

 

 

 

 

 

 

 

Maple leaf-like structures:

These are brown bulbous extensions taking the form of a maple leaf representing dermal aggregates of pigmented tumour cell

 

 

 

 

 

 

 

 

 

 

 

Spoke-wheel like structures:

These are projections from a central dark point giving the appearance of spokes.

 

 

 

 

 

 

 

 

 

 

 

 

 

Ulceration and crust:

Erosions and ulceration is common over many BCCs.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Non-pigmented BCCs:

 

Arborising telangiectasia and ulceration:

As outlined above these are important features of non-pigmented BCCs. Other features include shiny white areas (seen in PD) and short fine telangiectasias.
