Skin Challenge: DPN

Dermatosis papulosa nigra (DPN) is characterized by small brown or black spots found on the skin around the cheekbones and eyes. It can also be found on other areas of the face, neck, chest, and back. Some people with dermatosis papulosa nigra have a few, isolated spots while others have hundreds of spots. The spots may be flat or hang off the skin like a skin tag. Scaling, crusting, and ulceration do not occur.

The spots are neither cancerous nor medically concerning, but they may be itchy, irritating, or cosmetically undesired. DPN spots are usually present as multiple small, 1–5 mm diameter, smooth, firm, black or dark brown papules that are deemed another type of seborrheic keratosis.

The papules are symptomless but may be regarded as unsightly. They are common in people with skin of color, with Fitzpatrick skin types 4, 5, or 6. This condition affects up to 35 percent of African Americans, yet has a lower frequency in same group with a fairer complexion. Dermatosis papulosa nigra also occurs among dark-skinned Asians and Polynesians, but the exact frequency is unknown. Females are more frequently affected than males. Dermatosis papulosa nigra usually begins in adolescence. The incidence, number and size of lesions increases with age.

SPA MANAGEMENT

What is the cause of Dermatosis Papulosa Nigra in your client?

Dermatosis papulosa nigra is likely to be genetically determined with 40–50 percent of patients having a family history. It is believed to be due to a naevoid developmental defect of the hair follicle; otherwise, cause is unknown.  

Determine any medications, contraindications, and cautions before proceeding with any spa treatment.

Treatments that can be offered:

  • Electrodessication
  • Cryotherapy
  • Laser therapy

Estheticians: Treatment for DPN is complicated as it occurs mostly in people of color who are at a higher risk of developing pigmentation defects (lightening or darkening of the skin) and scarring following treatment. The result can be a blotchy or scarred appearance on the skin, which could be worse than the original dermatosis papulosa nigra spots.
