What is dematosis papulsa nigra?

Dematosis papulosa nigra (DPN) is a common dermatological condition characterized by the presence of multiple small, dark-brown to black papules (raised bumps) on the skin. These papules typically occur on the face, neck, chest, and back, but can also be found on other parts of the body. DPN is more common in people with darker skin tones and is usually not associated with any symptoms. Although the exact cause of DPN is unknown, it is thought to be related to hormonal changes and sun exposure. Treatment for DPN is usually not necessary, but some people may choose to have the papules removed for cosmetic reasons.
