Management of dermatosis papulosa nigra: a systematic review

Le résumé fourni par la source

Dermatosis papulosa nigra (DPN) is a variant of seborrheic keratosis that typically presents as hyperpigmented pedunculated papules on the face, trunk, and/or back in those with skin of color. Although benign, the lesions can cause significant discomfort and distress. Management options are limited and often unaffordable, as treatment is elective in most cases. This study was undertaken to provide an updated summary of safe and efficacious treatments for DPN. Five databases were searched to identify full-text publications reporting on treatments and outcomes in adults with DPN. Seventeen publications met inclusion criteria and were included: six cohort studies, one randomized controlled trial, five case report studies, one case series, and four pilot studies. Treatment options included simple excision, curettage, electrodesiccation, cryotherapy, topicals, and laser therapies. These modalities varied in their documented outcomes and associated potential adverse effect profiles. Postinflammatory hyperpigmentation is a common adverse effect that often leads to patient dissatisfaction. It can be mitigated with topical treatments aimed at reducing local inflammation. Study limitations included small sample size in individual studies, lack of consistent reporting of Fitzpatrick skin type, and lack of comparison to the standard treatment of electrodesiccation or curettage. Ultimately, treatment should consider the patient's Fitzpatrick type, treatment area, associated costs, and potential adverse effects.
