Superficial spreading melanoma on an arm

A 31-year-old man consulted for this pigmented lesion on his right arm.

Dermoscopy revealed pigmented lesion with the following dermoscopic signs:
  • asymmetry of colors and shape
  • regression area: depigmentation (black rectangle ) and blue gray dots (peppering) (yellow circle)
  • atypical reticular network (brown rectangle)
  • pseudopods (red arrow)

This lesion was excised and pathology confirmed the diagnosis of superficial spreading melanoma. Breslow index was 0,48 mm.
