Dermatosis papulosa nigra (DPN) is a unique skin condition seen primarily in persons of color. It appears as small, dark bumps and most commonly affects the forehead, cheeks, and neck. The bumps increase in size and number over time, initially appearing in people ages 20-30. Some people call them “flesh moles.” Bill Cosby, Morgan Freeman and Condoleezza Rice are notable people with the condition. It tends to occur slightly more frequently in women than in men.
What causes DPN?
The cause of dermatosis papulosa nigra is uncertain. There is a strong genetic basis for the disorder, and oftentimes the lesions can be seen in several members of the same family. Under the microscope, the lesions are a type of keratosis that is harmless. Dermatosis papulosa nigra is not a skin cancer, and it will not turn into a skin cancer.
How is DPN diagnosed?
The diagnosis is easily made by a dermatologist.
Can DPN be prevented?
No, because it is passed on genetically. One can treat the bumps when they are small to prevent them from becoming obvious and maintain a regular treatment program (every 1-4 years) to keep them away.
How is DPN treated?
Generally speaking, no treatment is necessary other than for cosmetic concerns. In certain circumstances, if the lesions are symptomatic (painful, inflamed or itchy) or cosmetically undesirable, the lesions can be treated via a minor in-office surgical procedure with excellent results. Your doctor will review treatment options with you and recommend the one that is most appropriate for your condition.
Action steps
Realize the condition is inherited and occurs later in life but does not turn into skin cancer. The spots may get worse over time, and they can be removed if they are irritated or unwanted. If DPN is undesirable, there are techniques used by an experienced dermatologist to provide excellent treatment results.

Do you recommend getting the moles scraped or lasered off?
What’s up with the word “nigra” in dermatosis papulosa nigra? What is the origin? I find it highly offensive.
Thanks for your comment/question.
Please don’t be offended. It is a medical term. Nigra is a Latin word.
It is pronounced Nie-grah
Dermatosis = affecting the skin
Papulosa = papule, bump
Nigra (Latin) = dark colored
So the term Dermatosis Papulosa Nigra means:
Dark colored bump that is found on/affects the skin
Nothing more.
I appreciate your question.
Is there a link between DPN and aging ? I have heard that people with moles, particularly dark skin, tend to have a slower aging process . Is there any proven correlation ?
Dr. Crutchfield, what procedure was used to remove the DPN in the male patient photos included in the article? I live in a small southern city and the dermatologists here do not recommend removing them due to possible changes in pigmentation once removed.. I would very much appreciate a recommendation for a board certified dermatologist in SC or the Charlotte, NC area. Capable of removing my DPN. Thank you
Often black dots, representing the blood veessels which feed the wart, are visible.
Afterward you soak the region getting it all nice and a lot of and after that rub away the warts with one
off those pumice stones or several fine sand papers.
But ddo we really want to drop that much money in something hat we may not have the ability to
do for partial the price.
If these warts at so easily removed, why do people like Morgan Freeman and Bill Cosby let them colonize all over their faces? These guys’ faces are important for making a living. I’m not saying their faces should be flawless. But with all their money, one would expect them to be spending some on fixing their facds.
