A 18-year-old man consulted for a pigmented lesion on his left heel.

Dermoscopy revealed a parallel ridge pattern and the presence of aggregated black globules, noticeably visible at the border of the lesion : this unique dermoscopic feature named "pebbles on the ridges" is typical of a subcorneal haemorrhage (or subcorcorneal hematoma, black heel).

Nice legs !

A 59-year-old patient consulted for this white lesion on her back.

Dermoscopy confirmed easily the diagnosis showing the legs of this charming bug ! A tick !

Dorsal red plaque

A 51-year-old man presented a slowly enlarging red plaque on his back.

Dermoscopy revealed:

• absence of pigment network
• thin arborizing vessels

A biopsy confirmed the diagnosis of superficial basal cell carcinoma.

In superficial BCC, vessels are often thinner than in other subtypes (nodular BCC).
