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)
