Dermatosis Papulosa Nigra
Dermatosis papulosa nigra (DPN) is a condition of many small, benign skin lesions on the face, a condition generally presenting on dark-skinned individuals. DPN is extremely common, affecting up to 30% of Black people in the US. From a histological perspective, DPN resembles seborrheic keratoses. The condition may be cosmetically undesirable to some patients. They should not be confused for Leser-Trélat sign, a sudden explosion of lesions due to a growing tumor.
