Treatment Outcomes for Dermatosis Papulosa Nigra Using Low-Intensity Electrodesiccation Device in African Patients.
J Cosmet Dermatol
December 2024
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.
Management of dermatosis papulosa nigra: a systematic review.
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.
Clinical and Dermoscopic Patterns of Basal Cell Carcinoma and Its Mimickers in Skin of Color: A Practical Summary.
Medicina (Kaunas)
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.
