DEMATOSIS PAPULOSA NIGRA-DPN
These are benign growths that occur frequently in African skin due to photo aging. Dermatosis Papulosa Nigra (DPN), a cluster of small seborrheic keratosis, is prominently located on the face, neck and upper trunk of both African men and women. They are small, brown or black bumps that are sometimes mistaken for moles. It is felt that a combination of heredity, aging and exposure to the sun are factors in the development of DPNs.
Since DPNs are non-cancerous, they do not have to be treated. They do, however, increase in number and size as women/men mature and it is for these reasons that many want them treated. It can be treated with cryosurgery, electrodessication, curettage or laser treatment. Side effects of removal may include light or black skin discolourations which usually fade rapidly especially if the skin is pretreated with a skin lightening agent.
