A small pigmented lesion on a leg

A 29-year-old woman consulted for  a small pigmented lesion on her right leg.

Dermoscopy revealed

• spoke wheel areas

Pathology revealed a superficial basal cell carcinoma 

What is this lesion on a leg (first case) ?

A 72-year-old woman consulted for this ulcerated lesion on her right leg.

Dermoscopy revealed:

• ulceration (crusts)
• central glomerular vessels regularly disposed
• blue-gray globules
• spokewheel areas

Discussion: blue-gray globules were the main sign in favor of a basal cell carcinoma (BCC), in association with ulceration and some spokewheel areas.

Nevertheless, glomerular vessels have not been reported in BCC. We think that, in our case, these glomerular vessels were due to a stasis dermatitis.

An excision was performed and pathology confirmed the diagnosis of BCC.

Nasal lesion.

A 72-year-old man consulted for a lesion on his nose.

Dermoscopy revealed:

• absence of pigment network
• arborizing blood vessels
• blue-gray globules
• spokewheel areas

in favor of a basal cell carcinoma and confirming the clinical hypothesis.

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
