### What is Dermatosis Papulosa Nigra? Dermatosis Papulosa Nigra (DPN) is a skin condition that appears as small, dark, or skin-colored bumps on the face, neck, and upper torso. These bumps are harmless and don't cause any ulcerations, scaling, or crusting. They typically start in adolescence as smooth, freckle-like bumps and gradually become rougher with time. DPN primarily affects people of African and Asian descent and tends to run in families. ### Causes and Risk Factors The exact causes of DPN are unclear, but it shares similarities with Seborrheic Keratoses, a common noncancerous skin growth. There may be a link between UV exposure and DPN development, especially in people with darker skin who use skin-lightening creams. DPN is more common in women and those with a family history of the condition. ### Diagnosis DPN can usually be diagnosed clinically without any tests. If there are doubts, a dermoscopy may be used to differentiate DPN from similar skin lesions. In rare cases, a skin biopsy may be taken if the growth is suspected to be cancerous. ### Treatment and Management DPN doesn't usually require treatment unless the bumps become itchy or you don't like their appearance. Treatment options include: - **Snipping the bumps off** - **Carbon-dioxide laser treatment** - **Potassium Titanyl Phosphate (KTP) laser therapy** These treatments may leave some scarring, and there's no guarantee the bumps won't return. Laser therapy is effective in reducing the appearance of DPN and leaves little or no scarring. Consult your dermatologist to determine the best treatment option for your skin.
