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 [1].



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

However, some features are more common in nodular BCC compared to other BCC sub-types [2][3][4]. These include:

  • Arborizing vessels
  • Blue-gray ovoid nests
  • Ulceration

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
