Rosacea: Practical Guidance and Challenges for Clinical Management.

Rosacea is a common chronic dermatosis. Clinically, rosacea can present with flushing, erythema, papules, pustules, telangiectasias, phymatous changes, pruritus, burning, and stinging. In 2017, the National Rosacea Society Expert Committee recommended a phenotype-based classification for therapy.

A survey of United States dermatologists' knowledge, attitudes, and practices with intramuscular triamcinolone.

Since the 1970s, intramuscular triamcinolone (IMT) has been available as an option for systemic corticosteroid use in dermatology. Although shown to be safe and effective in early studies, this method of systemic corticosteroid delivery fell out of favor in the 1980s in many United States residency programs. To identify factors associated with US dermatologists' preferences for and use of IMT we surveyed a random sample of US board-certified dermatologists to assess knowledge, attitudes, and practices regarding IMT in dermatologists' daily clinical practice.

Evaluation of Skindex-16 construct validity in routinely collected psoriasis data: a retrospective analysis of the relationship between overall physician global assessment scores and Skindex-16 and measure discordance.

Patient-reported outcome measures (PROMs) capture disease severity metrics from the patient's perspective, including health-related quality of life (HRQL). Disease-specific validation of PROMs improves their clinical utility. We evaluated construct validity (HRQL) for Skindex-16 in routinely seen psoriasis patients and characterized instances of discordance between Skindex-16 scores and clinician-reported outcome measure of disease severity.

Amelanotic Melanoma Treated as Fungal Infection for Years.

This study describes a case of amelanotic lentigo maligna melanoma in a 69-year-old female that had been growing for approximately 5 years. The asymptomatic lesion had been previously diagnosed and treated as a fungal skin infection, an inflammatory rash, and an actinic keratosis that did not respond to standard treatments. Biopsy revealed confluent and nested atypical melanocytes at the dermal-epidermal junction, consistent with melanoma in situ.
