Whitish area

A 17-year-old girl presented a pigmented lesion with a lateral  depigmentation.

Dermoscopy  revealed a globular pattern associated with a whitish structureless area. On this whitish area some vessels were observed. There were no signs of peppering.

This lesion was excised and pathology revealed a benign dermal melanocytic nevus with a fibrous involution.

Whitish structureless area can be observed in:
  • fibrous involution
  • after traumatism
  • in case of regression (with peppering)
