A whitish lesion

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

A temporal lesion

A 60-year-old woman consulted for this temporal  pigmented lesion

 Dermoscopy revealed:

• blue-gray dots / globules
• leaf-like areas

Pathology was in favor of a basal cell carcinoma

A small lesion...

A 52-year-old woman consulted for a cutaneous check up.
Examination revealed this lesion.

Dermoscopy revealed:

• maple leaf-like areas (black arrow)
• blue ovoid nests (red circle)
• structureless area (red arrow)

This lesion was excised and pathology revealed a superficial basal cell carcinoma.

A facial telangiectatic tumor

A 67-year-old woman consulted for this small lesion on her left cheek.


Dermoscopy was typical of a basal cell carcinoma: ulceration, arborizing vessels and a (subtle) leaf -like area.

Leaves

A 48-year-old woman presented a pigmented lesion on her sternal area:

Dermoscopy revealed:

• a non melanocytic pattern
• typical leaf-like structures
• one spoke wheel-like structure

in favour of a basal cell carcinoma

Leaf-like structures

A 92-year-old woman presented a red tumor on her neck.

Dermoscopy revealed many brown structures with a leaf-like configuration located at the periphery of the lesion. This was typical of leaf-like structures, also called maple leaf-like areas in the first publications.

Leaf-like structures are quite exclusively found in basal cell carcinomas but have also been reported in featureless melanomas.
