Dermatosis papulosa nigra: a clinically and histopathologically distinct entity.

Clin Dermatol 2017 Sep - Oct;35(5):491-496. Epub 2017 Jun 8.

Department of Dermatology and Cutaneous Biology, and the Jefferson Center for International Dermatology, Sidney Kimmel Medical College at Thomas Jefferson University, Philadelphia, Pennsylvania.

Dermatosis papulosa nigra was first described by Aldo Castellani (1874-1971) more than 90 years ago, and it has since been presumed to be a variant of seborrheic keratosis. Despite their morphologic similarities both macroscopically and microscopically, key differences have yet to be explained. These lesions also exhibit different demographics, with dermatosis papulosa nigra having a predilection for dark-skinned individuals and a female predominance. Read More

A Clinicopathological and Dermoscopic Correlation of Seborrheic Keratosis.

Indian J Dermatol 2016 Nov-Dec;61(6):622-627

Department of Dermatology Venereology and Leprosy, Father Muller Medical College Hospital, Mangalore, Karnataka, India.

Background: Seborrheic keratosis (SK) is the most common benign epidermal tumor of the skin. Even though SK has been well characterized clinically, dermoscopically, and histopathologically, data regarding clinical dermoscopic and histopathological correlation of different types of SK are inadequate.

Aim: We carried out this study to establish any correlation between the clinical, dermoscopic, and histopathological appearance of SK and its variants. Read More

Dermatosis Papulosa Nigra and 10,600-nm CO2 laser, a good choice.

J Cosmet Laser Ther 2014 Jun 18;16(3):114-6. Epub 2013 Nov 18.

Department of Surgery and Translational Medicine, Section of Dermatology, University of Florence , Florence , Italy.

Dermatosis Papulosa Nigra (DPN) is a common skin condition observed in black people and considered a benign epithelial tumor, and more specifically, a particular topographic form of seborrheic keratosis. We treated five female patients affected by DPN with 10,600-nm CO2 laser. We propose the 10,600-nm CO2 laser as a valid therapeutic option in patients affected by DPN, since the treatment is well tolerated, causes no major side effects, and is effective and long lasting.

Postprocedural wound-healing efficacy following removal of dermatosis papulosa nigra lesions in an African American population: a comparison of a skin protectant ointment and a topical antibiotic.

J Am Acad Dermatol 2011 Mar 17;64(3 Suppl):S30-5. Epub 2011 Jan 17.

College of Physicians and Surgeons, Columbia University, New York, USA.

Background: Removal of dermatosis papulosa nigra (DPN) lesions results in superficial cutaneous wounds that are frequently treated with topical antibiotic ointments. We hypothesize that antibiotics are not necessary for effective and safe healing of such wounds.

Objective: This study compared the wound healing efficacy and safety of the skin protectant Aquaphor Healing Ointment (AHO) (Beiersdorf Inc, Wilton, CT) and Polysporin first-aid ointment (Poly/Bac) (polymyxin B sulfate/bacitracin zinc) (Johnson & Johnson, New Brunswick, NJ) after removal of DPN lesions.

National Institute for Health, Migration and Poverty, Via di San Gallicano 25/a Roma, Italy.

Dermatosis papulosa nigra (DPN) is a benign epithelial tumor that is common in dark-skinned people. Although the diagnosis is easily made on medical examination, DPN is characterized by a chronic and worsening course. Therefore, even if DPN is a benign disease, the lesions are unaesthetic and the therapeutic options are quite inefficient. Read More
