Dermatosis Papulosa Nigra (also known as DPN) is brown/black coloured bumps, usually present on the face, neck and upper part of the body. These bumps typically affect those of African origin, but sometimes can affect Hispanic and Asian people too. DPN can also sometimes be present on the top part of the eyelids.
DPN usually presents itself to the body by first appearing on the face. Many decades later it may then spread to other body parts, but mainly the upper torso together with the face and neck. The bumps are unpleasant visually and can notably affect the psyche of an individual. However, the bumps are totally harmless, and there is no such danger of their transformation into skin cancer. Statistically, over one third of the black population in North America are affected by Dermatosis Papulosa Nigra (DPN).
