Dermatosis Papulosa Nigra
Dermatosis Papulosa Nigra is skin condition that appears as black or brown papules on one’s skin. They are usually flat and elevated a little bit from the skin surface. These little mole-like dots are usually between 1-5mm in size. In most cases they appear on the cheeks, forehead torso or neck region. There are also reported cases of Dermatosis Papulosa Nigra appearing underneath the eye.
It is not clear to dermatologists a to what the exact cause of Dermatosis Papulosa Nigra is, however, one possibility is that there might be a mutation happening in the pipes. Also, Dermatosis Papulosa Nigra is likened to be linked with genetic predisposition. Sources have come out to say that one can inherit it from one’s lineage.
Dermatosis Papulosa Nigra is common among blacks and on blacks it is characterised by multiple small hyperpigmented asymptomatic papules on the faces of adult blacks. Dermatosis Papulosa Nigra usually develops on darker skin as multiple small black and brown papules. While it mostly affects African Americans, dark-skinned Asians and Polynesians are also at risk.
Epidemiology of Dermatosis Papulosa Nigra
According to studies, Dermatosis Papulosa Nigra occurs in about 35% of the black population and an unknown percentage of Asians. Studies have also shown that black women are more predisposed to Dermatosis Papulosa Nigra than black men. Symptoms are apparent starting in adolescence. With age, the papules tend to increase in size as well as number. Contact Buckhead Dermatology in Atlanta and College park for expert advice
There are three levels of severity:
- Mild- less than 10 papules
- Moderate-more than 10 papules
- Severe-more than 50 papules
Because Dermatosis Papulosa Nigra is a benign condition, most people affected tend to seek treatment help from dermatologists for cosmetic purposes. Over the past few years, surgical procedures using special lasers have shown to be a promising treatment for Dermatosis Papulosa Nigra. Other orthodox methods include: cryosurgery (freezing), curettage (scraping), and electrocautery (burning). However these methods increase the risk of scarring, the keloid development and unwanted pigmentation problems.
Since DPN is hereditary, there’s not a lot you can do to prevent it. However, you can slow the growth if you have good skin-care habits, like wearing sunscreen. “UV exposure promotes DNA changes in skin cells and can promote cell growth,” says Dr. Desai. Time in the sun can also give the spots a tan and make them darker (aka more noticeable). To slow the spread of DPN, both dermatologists recommend daily broad-spectrum sunscreen use.
You can also stock up on skin-care products with chemical exfoliants. “One treatment that can really help keep [these spots] at bay is washing your face with a salicylic or glycolic acid wash,” says Dr. Sherrie-Ann Straughn. Note: This isn’t going to keep them from popping up, but it can stall them from growing larger. Dr. Desai says using retinol products, which increase cell turnover, can also help diminish the appearance of DPN—but, again, it’s not a cure.
