A slowly enlarging pigmented lesion

A 32-year-old woman consulted for a pigmented lesion on her left arm. This lesion was slowly enlarging for 3 years.

 Dermoscopy revealed:

  • an atypical reticular pattern with a total disorganization
  • multiple colors
  • signs of regression

 Two punch biopsies were performed.
Pathology was in favor of melanoma in situ.
Lesion was excised with a 0.5 margin.
