Consultant Dermatologist, Aalborg University, Aalborg, Denmark.
Objective: We aimed to document the treatment outcomes of African patients treated with low-intensity electrodesiccation for DPN's. Other treatment options for DPN's include snip excision, light curettage, cryotherapy, and lasers devices such as PDL, Nd: YAG, KTP, and CO2, which are generally unsafe for darker skin types and come with high costs.
Methods: Nonprobability convenience sampling of patient records was used to extract retrospective data on demographics and treatment outcomes according to the inclusion criteria.

Int J Dermatol
October 2024
Department of Dermatology, LSU Health Sciences Center-New Orleans School of Medicine, New Orleans, LA, USA.
Article Synopsis
- Dermatosis papulosa nigra (DPN) is a benign skin condition characterized by hyperpigmented, pedunculated papules, primarily affecting individuals with darker skin tones, and can lead to discomfort and distress.
- This study reviews existing literature on treatment options for DPN, encompassing 17 relevant publications, including various study types like cohort and randomized controlled trials.
- Treatment methods include excision, curettage, cryotherapy, and laser therapies, but may cause side effects like postinflammatory hyperpigmentation; treatment strategies should be tailored to individual factors such as skin type, costs, and potential adverse effects.

August 2024
Institute of Dermatology, Department of Medical Area, University of Udine, 33100 Udine, Italy.
Article Synopsis
- Diagnosing basal cell carcinoma (BCC) in individuals with darker skin tones (dark phototypes IV-VI) is difficult due to varied presentations and fewer identifiable clues; dermoscopy can aid in identifying BCC in these patients.
- This review provides a comparison of BCC's clinical and dermoscopic patterns in people of color to those in lighter-skinned individuals, identifying common mimickers like squamous cell carcinoma and melanoma.
- Key dermoscopic features of BCC in darker skin include blue, black, and gray dots, with arborizing vessels being the primary indicator, while unique conditions in darker skin such as dermatosis papulosa nigra are also considered in differential diagnosis.

Dermatosis papulosa nigra (DPN) is a skin condition characterized by pigmented sessile and pedunculated papules on the body, particularly on the face and other sun-exposed areas, that can cause cosmetic disfigurement and varying degrees of distress and psychosocial concern among patients. We sought to evaluate the effect of DPN on quality of life (QoL). A 39-item questionnaire was administered to 50 African-American (AA) adults, 48 women and two men, with an average age of 51.

Gradations in skin color are a consequence of differing amounts of melanin and their varying distribution. Although many darkly pigmented skin lesions are melanocytic and can be attributed to melanin content, the color of a black lesion can also be due to blood, necrotic tissue, or exogenous pigment. The source, pattern, and distribution of the color in black lesions usually offer important insight into its etiology.
