DPN’s Moles

Home / DPN’s Moles

Dermatosis papulosa nigra(DPN’s) is a unique skin condition seen primarily in persons of color. It appears as small, dark bumps and most commonly affects the face, neck, chest, and back.
We are able to successfully treat DPN’s in our office.

The cause of dermatosis papulosa nigra is uncertain. There is a strong genetic basis for the disorder, and oftentimes the lesions can be seen in several members of the same family. Under the microscope, the lesions are a type of keratosis that is harmless. Dermatosis papulosa nigra is not a skin cancer, and it will not turn into a skin cancer. The condition is chronic, with new lesions appearing over time.

Physical

Dermatosis papulosanigra is characterized by multiple, firm, smooth, dark brown to black, flattened papules that measure 1-5 mm in diameter. Lesions occur mainly on the malar area of the face and the forehead, although they also may be found on the neck, upper back, and chest. A small percentage of patients have similar lesions on the upper trunk. Scaling, crusting, and ulceration do not occur.

Lesions usually begin during puberty. They tend to increase steadily in number and size as the individual ages
