BACKGROUND Primary cutaneous lymphomas (PCL) are a multifaceted spectrum of cutaneous T cell lymphoma (CTCL) and cutaneous B cell lymphomas (CBCL). Mycosis fungoides (MF) is a rare subset of CTCL that primarily affects adults, and its occurrence in children is exceedingly rare. Most pediatric MF manifests as hypopigmented patches resembling other benign dermatoses, causing diagnostic challenges.

A niche in the context of microorganisms defines the specific ecological role or habitat inhabited by microbial species within an ecosystem. For the human commensal Malassezia, the skin surface is considered its primary niche, where it adapts to the skin environment by utilising lipids as its main carbon and energy source. However pathogenic characteristics of Malassezia include the production of allergens, immune modulation and excessive lipid utilisation, which result in several diseases such as pityriasis versicolor, seborrheic dermatitis, Malassezia folliculitis and atopic dermatitis.

Indian J Dermatol
October 2024
From the Division of Biological Sciences, Academy of Scientific and Innovative Research (AcSIR), Ghaziabad, Uttar Pradesh, India.
Background: Psoriasis (PS), vitiligo (VT), and (PR) are chronic skin diseases often occurring as a consequence of exaggerated immune responses. These skin manifestations can be triggered as a result of the molecular mimicry between viral protein (s) and host protein (s), which could generate auto-antibodies. In addition, it can be hypothesised that skin diseases are manifestations of the reduced immunity that is observed in chronic hepatitis B virus (HBV)-infected individuals.

Department of Dermatology, University of Illinois College of Medicine, Chicago, IL, USA.
Background: While IL-23 inhibitors, which include guselkumab, tildrakizumab, and risankizumab, are currently FDA-approved solely for the treatment of psoriasis, several other inflammatory skin conditions have been associated with elevated IL-23 levels. The purpose of this review is to summarize and interpret the literature surrounding the off-label uses of IL-23 inhibitors in dermatologic practice.
Methods: We conducted searches on PubMed and for clinical trials, observational studies, case series, and case reports assessing use of the three IL-23 inhibitors for non-psoriatic dermatologic conditions.
