Welcome to the March 2020 issue of The Journal of Clinical and Aesthetic Dermatology. We begin the issue with an original research article from Janeczek et al, in which the authors used a standard Wood’s lamp to visualize porphyrins associated with Corynebacterium minutissimum (C. minutissimum) in 30 patients with inverse psoriatic plaques.
Background. Inverse psoriasis is characterized by erythematous nonscaly plaques in intertriginous regions. Similarly, erythrasma, a superficial infection caused by Corynebacterium minutissimum (C. minutissimum), is also found in skin folds with red-brown lesions, making the distinction between psoriasis and erythrasma difficult.
Background. Dr. Frederic Mohs believed that surgery can spread a melanoma; to prevent this, he applied an inactive black paste vehicle containing the active ingredient 50% zinc chloride solution to melanomas to kill and fix (i.e., preserve) tissue; this is termed fixed-tissue surgery.
Hailey-Hailey disease (HHD), or chronic benign familial pemphigus, is a rare inherited acantholytic dermatosis, characterized by chronic, recurrent vesicles, erosions, and maceration in intertriginous sites.
Neutrophilic urticarial dermatosis (NUD) is rare and poorly understood. First described in 2009, NUD has been reported in association with systemic and autoinflammatory disorders.
