Dermatosis papulosa nigra (DPN) is a benign cutaneous condition common among blacks. It is usually characterized by multiple, small, hyperpigmented, asymptomatic papules on the face of adult blacks. Histologically, dermatosis papulosa nigra resembles seborrheic keratoses. The condition may be cosmetically undesirable to some patients. See the image below.
