DERMATOSIS PAPULOSA NIGRA (DPN)

Understanding Dermatosis Papulosa Nigra in Skin of Color

Dermatosis Papulosa Nigra (DPN) is a benign skin condition characterized by small, dark, raised papules, most commonly appearing on the face and neck. These papules are usually smooth, round, and range from 1–5 mm in diameter.

Why Does DPN Happen?

DPN is believed to be a variant of seborrheic keratosis, a common benign skin growth. The exact cause is unknown, but genetics play a significant role. DPN is much more common in individuals with darker skin tones, particularly those of African, Asian, or Hispanic descent. It often runs in families, suggesting a hereditary component.

Why is DPN More Common in Skin of Color?

Research shows DPN affects up to 35% of Black adults in the United States. The higher prevalence in skin of color is likely due to genetic predisposition and differences in melanin production and skin biology. The papules themselves contain increased melanin, which makes them more visible and pigmented in darker skin.

Is DPN Dangerous? Is there any Cancer Risk?

DPN is completely benign and not cancerous. There is no evidence linking DPN to skin cancer or any other serious health condition. However, because the papules can resemble other pigmented lesions, it’s important to confirm the diagnosis, especially if there are changes in size, color, or shape.

 Risks Associated with DPN

While DPN is harmless, some people may experience:

Cosmetic concerns: The appearance of DPN can cause emotional distress or self-consciousness.

Irritation: Rarely, papules may become irritated by shaving, jewelry, or clothing.

Scarring: Attempting to remove DPN at home can lead to scarring, especially in skin of color, which is more prone to hyperpigmentation and keloid formation.

Treatment Options for DPN 

Treatment is not medically necessary but may be sought for cosmetic reasons.

Options include:

Electrodessication: Using a small electric current to dry and remove the papules.

Curettage: Gently scraping off the papules.

Laser Therapy: Certain lasers can target and remove DPN with minimal scarring.

Cryotherapy (Freezing): Less commonly used, as it can cause pigment changes in darker skin.

Important: All procedures should be performed by a medical professional experienced in treating skin of color to minimize the risk of post-inflammatory hyperpigmentation, scarring, or keloid formation.

Final Thoughts

Dermatosis Papulosa Nigra is a common, benign skin condition that predominantly affects people with skin of color. While it poses no cancer risk or health threat, treatment is available for those who are bothered by its appearance. If you notice new or changing skin lesions, always consult a medical professional to rule out other conditions.
