Nodular Basal Cell Carcinoma
Nodular basal cell carcinoma (nBCC) is the most common sub-type and accounts for approximately 50-80% of BCCs. Clinically is manifests as an elevated tumor (papule or nodule) with a pearly and translucent margin and telangiectasia .
General dermoscopic features
As nodular BCC is the "classic" BCC type, all of the dermoscopic features mentioned in the general BCC sub-chapter can be found in nodular BCC:

Specific dermoscopic features
- Arborizing vessels
- Blue-gray ovoid nests
Features that are less likely to be seen in nodular BCC compared to other BCC subtypes include:
- Leaf-like structures
- Spoke wheel-like structures
- Multiple small erosions
