From the Research
No, acrochordons (skin tags) and dermatosis papulosa nigra (DPN) are not the same condition. Acrochordons are small, soft, flesh-colored or brown growths that typically appear in skin folds such as the neck, armpits, groin, and eyelids. They occur in people of all ethnicities and are associated with obesity, diabetes, and friction. In contrast, dermatosis papulosa nigra presents as multiple small, dark brown to black papules primarily on the face, particularly the cheeks and around the eyes. DPN predominantly affects individuals with darker skin types, especially those of African or Asian descent, and has a strong genetic component 1.
Some key differences between the two conditions include:
- Appearance: Acrochordons are typically flesh-colored or brown, while DPN lesions are dark brown to black
- Distribution: Acrochordons occur in skin folds, while DPN lesions occur primarily on the face
- Demographic prevalence: Acrochordons occur in people of all ethnicities, while DPN predominantly affects individuals with darker skin types
- Genetic component: DPN has a strong genetic component, while acrochordons do not 2
While both conditions are benign and can be removed for cosmetic reasons through similar methods (snipping, freezing, or electrocautery), they differ in their appearance, distribution patterns, and demographic prevalence. Neither condition requires treatment unless they cause discomfort or cosmetic concerns 3.
It's worth noting that treatment options for DPN are limited and often unaffordable, as treatment is elective in most cases. However, a systematic review of treatments for DPN found that various modalities, including simple excision, curettage, electrodesiccation, cryotherapy, topicals, and laser therapies, can be effective in removing lesions and improving cosmetic appearance 1. Ultimately, treatment should consider the patient's Fitzpatrick type, treatment area, associated costs, and potential adverse effects.
