Plantar nevus

A 25-year-old woman consulted for a pigmented lesion on her right foot.
Dermoscopy revealed a parallel furrow pattern and a whitish structureless area.
On the middle of this structureless area a keratotic lesion was noticed in favor of a callus.
An excision was performed and pathology revealed a benign melanocytic nevus.
The structureless area was caused by the chronic friction of this nevus against shoes.
