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)
