Dermatosis papulosa nigra in Dakar, Senegal

Abstract

This study on 30 cases of DPN is the first in Senegal. The classic female predominance, family predisposition, and photodistribution of the lesions were found. The lesions were profuse, with a background of artificial depigmentation. This suggests that the sun may be an etiopathogenic factor. Aesthetic problems are an indication for ablation of the lesions using a method that minimises the risk of scarring. Artificial depigmentation may cause delayed healing and dyschromic scars, as may the application of carbon dioxide snow.
