Treatment of dermatosis papulosa nigra with a 1064 nm Nd:YAG laser: report of two cases.

Dermatosis papulosa nigra (DPN) is a chronic skin condition characterized by verrucous hyperpigmented papules on the face, neck and upper trunk in African American patients. The lesions are more common in females and in older patients. Although the lesions are benign, treatment is often sought for cosmetic reasons. We report two cases of patients with facial DPN who achieved an excellent cosmetic result following a single treatment with a long-pulsed 1064 nm Nd:YAG laser. We suggest this modality for consideration in treating patients with DPN.
