A third nipple.

A 28-year-old man consulted for this pigmented lesion located under his nipple. He was thinking this lesion was present since birth.

Dermoscopy revealed a central hypo-pigmented area with a peripheral pigmented reticulation.
This feature looks like a dermatofibroma

This lesion was a surnumerary nipple (accessory nipple)
