Approach Considerations

No treatment generally is indicated for dermatosis papulosa nigra unless lesions are cosmetically undesirable. Aggressive therapeutic modalities have been complicated by postoperative hyperpigmentation or hypopigmentation or scarring. Keloid formation is a potential complication. Therefore, conservative treatment is advisable.

Abrasive curettage with or without anesthesia, [5] superficial liquid nitrogen cryotherapy, and electrodesiccation followed by curettage have been shown to be effective. Laser therapy has also been reported. [6, 7, 8] Both EMLA (topical lidocaine/prilocaine cream) and LMX (topical lidocaine cream) creams are effective for providing topical anesthesia. [9] Use caution with all therapies to minimize the depth of treatment.
