Dermatosis Papulosa Nigra – Safe Removal by Consultant Dermatologist in London

Understanding dermatosis papulosa nigra

Dermatosis papulosa nigra (DPN) is a type of benign skin growth. The condition produces multiple small, pigmented bumps that are typically smooth and dome-shaped. They most often appear on the face, particularly around the eyes and cheeks, but can also be found on the neck, chest, and back. While DPN does not carry medical risk, many patients seek advice due to cosmetic or self-esteem concerns.

Causes and risk factors

The exact cause of DPN is unknown, but genetic predisposition plays a strong role. It is far more common in people with darker skin types (Fitzpatrick skin types IV–VI), and tends to run in families. Hormonal factors may also influence its development, with lesions often increasing in number with age.

Clinical features

DPN lesions are typically:

• Small (1–5 mm in diameter)
• Dark brown to black in colour
• Round, smooth, and dome-shaped
• Painless and non-itchy, though occasionally irritated by friction

They are often confused with seborrhoeic keratoses or even melanomas, which is why professional assessment is recommended.

Who is affected?

Dermatosis papulosa nigra is particularly common in people of African, Afro-Caribbean, and Asian descent. It usually develops during adolescence and increases in number with age. Women may seek treatment more often due to facial visibility of the lesions.

Diagnosis

Diagnosis is typically clinical and straightforward for an experienced dermatologist. Dermoscopy may be used to distinguish DPN from other pigmented lesions. A biopsy is rarely necessary, but may be performed if there is diagnostic uncertainty.

Management and treatment

As DPN is harmless, treatment is not medically required. However, many patients request removal for aesthetic reasons or due to irritation. Options include:

• Cryotherapy: Freezing with liquid nitrogen is generally avoided, as it may cause hypopigmentation in darker skin tones.
• Electrosurgery: A precise electric current removes the lesion with minimal bleeding.
• Curettage: Scraping of the lesion under local anaesthetic.
• Laser therapy: Advanced lasers can safely target and remove pigmented bumps with reduced risk of scarring.

Choice of treatment depends on the number of lesions, skin type, and patient preference.

Prevention and aftercare

DPN cannot be prevented due to its genetic basis. After treatment, good wound care is essential to minimise scarring or pigment change. Sun protection is especially important in the healing phase.

Special considerations for skin of colour

Because DPN is most common in darker skin types, treatment requires specialist expertise. Certain techniques such as cryotherapy can cause unwanted light patches. At Skinhorizon, we use methods that are safe and effective for skin of colour.
