Dermatosis papulosa nigra : ウィキペディア英語版 | 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.〔Grimes PE, Arora S, Minus HR, Kenney JA Jr. Dermatosis papulosa nigra. Cutis. Oct 1983;32(4):385-6, 392.〕 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. ==Pathophysiology== The pathophysiology of DPN is unknown. Evidence of family history may suggest a genetic propensity.
