Rosacea has been reported less frequently among individuals with skin of color than in those with white skin, but rosacea is not a rare disease in this population. In fact, rosacea might be underreported and underdiagnosed in populations with skin of color because of the difficulty of discerning erythema and telangiectasia in dark skin. The susceptibility of persons with highly pigmented skin to dermatologic conditions like rosacea, whose triggers include sun exposure, is probably underestimated. Many people with skin of color who have rosacea might experience delayed diagnosis, leading to inappropriate or inadequate treatment; greater morbidity; and uncontrolled, progressive disease with disfiguring manifestations, including phymatous rosacea. In this article, we review the epidemiology of rosacea in skin of color and highlight variations in the clinical presentation of rosacea across the diverse spectrum of patient populations affected. We present strategies to aid in the timely diagnosis and effective treatment of rosacea in patients with skin of color, with an aim of promoting increased awareness of rosacea in these patients and reducing disparities in the management of their disease., (Copyright © 2018 American Academy of Dermatology, Inc.

Background: Acne fulminans (AF) is a severe variant of inflammatory acne. It typically manifests as an explosive worsening and ulceration of skin lesions, and can be associated with systemic symptoms. However, there is a paucity of evidence-based information and no clear guidelines concerning the classification and treatment of AF., Objective: To better define the spectrum of AF and its variants, devise optimal therapeutic approaches, and identify areas of future research., Methods: A panel of physicians with expertise in severe acne vulgaris was convened after a comprehensive literature review of severe acne variants. Priority topics were reviewed and presented by each panelist at a 5-hour conference. Following review of the audiotape and scribed notes from the conference, surveys were utilized to address points of controversy and to clarify consensus recommendations., Results: Appropriate clinical case presentations and consensus survey questions were utilized to create final recommendations based on both the literature and the expert consensus., Limitations: Limited evidenced-based data and prospective studies in the literature concerning the treatment of AF is available., Conclusion: These guidelines better characterize AF and provide health care practitioners approaches to the classification, treatment, and prevention of AF and its variants., (Copyright © 2016 American Academy of Dermatology, Inc.

Acne is one of the most common disorders treated by dermatologists and other health care providers. While it most often affects adolescents, it is not uncommon in adults and can also be seen in children. This evidence-based guideline addresses important clinical questions that arise in its management. Issues from grading of acne to the topical and systemic management of the disease are reviewed. Suggestions on use are provided based on available evidence., (Copyright © 2016 American Academy of Dermatology, Inc. Published by Elsevier Inc. All rights reserved.)

The differential diagnosis of subcutaneous lesions of the scalp is extensive and includes many tumors with intracranial and intraosseous extension. The vast majority of lesions seen by the dermatologist will be benign. However, certain lesional characteristics increase the likelihood of a serious disorder and these must be evaluated preoperatively. We review the important features of subcutaneous scalp lesions and suggest a systematic approach to diagnosis based on patient age, lesion morphology, location, and radiographic findings.
