Dermatosis papulosa nigra dessication

 

Dermatosis papulosa nigra (DPN) is a benign cutaneous condition common among blacks. It is usually characterized by multiple, small, hyperpigmented, asymptomatic papules on the face of adult blacks. Histologically, dermatosis papulosa nigra resembles seborrheic keratoses. The condition may be cosmetically undesirable to some patients.

 

Dermatosis papulosa nigra 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.

 

 

Causes

 

Dermatosis papulosa nigra is likely to be genetically determined, with 40-54% of patients having a family history of involvement. Dermatosis papulosa nigra is believed to be caused by a nevoid developmental defect of the pilosebaceous follicle. Hairston et al have suggested that dermatosis papulosa nigra should be classified within the group of epithelial nevi.[4]
