Nasal pigmented lesion

A 85-year-old woman consulted for a pigmented lesion on the tip of her nose.

Dermoscopy revealed:
  • a pseudo-pigmented network (due to the facial localisation)
  • asymmetric pigmentation of the follicular openings
  • slate gray dots disposed as annular- granular structures

Clinical and dermoscopic features were in favor of a lentigo maligna melanoma which was confirmed by a punch biopsy.
