DERMATOSIS PAPULOSA NIGRA
Dermatosis papulosa nigra (DPN) is a variant of seborrheic keratoses that presents as multiple brown to black papules on the cheeks of darker-skinned individuals.
Multiple, brown, papules, small plaques and pedunculated lesions occur on the face, neck, and upper trunk in a darker-skinned patient. Histologically, DPN resembles the seborrheic keratosis.
No treatment is needed. If the patient desires, several destructive modalities may be done including scissors excision, light cautery, and/or electrodesiccation. An alternative is the application of EMLA for anesthesia followed by light electrocautery. Cryotherapy should not be done as it may cause hypopigmentation.
