Dermatosis Papulosa Nigra
Dermatosis Papulosa Nigra (DPN) is a harmless skin condition that is common in individuals with darker skin type. Although it is commonly seen in Afro-Caribbeans, we encounter many Asians with similar condition as well. It usually appears during the adolescent period, and increases in size and number with age. Females appear to have a greater prevalence of dermatosis papulosa nigra compared to men. In about half of DPN cases, it may even run in families.

Does It Cause Harm?
No, it does not. Dermatosis Papulosa Nigra does not develop into skin cancer nor does it signify any underlying medical illness.
Dermatosis Papulosa Nigra Treatments
Being a benign and harmless condition, it is not necessary to treat dermatosis papulosa nigra.
We understand that many individuals with DPN may find the appearance of it undesirable, and therefore prefer its removal. There are a variety of methods to remove dermatosis papulosa nigra skin lesions. The selection of the treatment modality takes into account the downtime, potential side effects of the treatments and costs.
Treatment methods to remove Dermatosis Papulosa Nigrans include electrodessication, cryotherapy (liquid nitrogen) and laser surgery. The Nd:YAG Laser, CO2 (Carbon Dioxide) Laser and Pulsed Dye Laser systems have been used to treat DPN. In one study, CO2 Laser surgery for dermatosis papulosa nigra has been shown to have low complication rates with a high degree of patient satisfaction. The healing time takes about a week, and side effects such as skin hyperpigmentation, hypopigmentaion and scarring are minimal in our clinical experience.
