Cutis. 1983 Oct;32(4):385-6, 392.
The incidence and natural history of dermatosis papulosa nigra was assessed in eighty-two black patients. The overall incidence in the study population was 77 percent, with a predominance in women of almost 2:1. Fifty-four percent of these patients reported that other members of their families were also affected. The peak incidence and number of lesions occurred in those patients in their sixties. Fair-complexioned blacks had the lowest frequency of involvement. These findings confirm those of other investigators; however, we report a higher than average incidence of involvement in the population we studied.
