A 48-year-old woman consulted for a whitish scar-like lesion on her back.  

Clinical picture: whitish scar-like lesion with a pigmented border. Patient has a background of former heavy sun exposure.

At dermoscopy:

• no signs in favor of a melanocytic lesion
• a structureless  scar-like white pattern
• pinkish areas without any vascular structures
• a peripheral pigmentation (red square) in favor of leaf-like areas

Pathology revealed a superficial basal cell carcinoma

Dermoscopy revealed a blue homogeneous pattern and some barely visible arborizing tree vessels in favour of a basal cell carcinoma.

This lesion was excised and pathology confirmed the diagnosis of basal cell carcinoma.

The almost entire area of this basal carcinoma was pigmented: arborizing vessels are seen in the upper right quadrant.

Pigmented basal cell carcinoma

A 67-year-old man consulted for a pigmented tumor on his right forearm. Dermoscopy revealed a central ulceration, arborizing blood vessels and blue ovoid nests. The lesion was excised and pathology confirmed the diagnosis of basal cell carcinoma.
