RESUMEN
INTRODUCTION: Mogamulizumab is an anti-C-C chemokine receptor 4 antibody that is increasingly being used to treat T-cell malignancies such as cutaneous T-cell lymphoma, adult T-cell leukemia-lymphoma, and peripheral T-cell lymphoma. Because CCR4 is expressed on both malignant T-cells and regulatory T-cells (Tregs), mogamulizumab can be associated with increased immune-related adverse events (irAEs). While there is abundant literature on mogamulizumab-associated rash (MAR) and graft-versus-host disease (GVHD), other reported irAEs have not been collated into a single review. AREAS COVERED: This narrative review covers irAEs associated with mogamulizumab in patients with T-cell lymphomas, focusing on events other than MAR and GVHD. We searched PubMed and Google Scholar for case reports, case series, chart reviews, and clinical trials published from inception to March 2024. Identified events include alopecia, vitiligo, arthritis, psoriasis, myocarditis, myositis/polymyositis, hepatitis, and others. EXPERT OPINION: Mogamulizumab's ability to augment the host immune response through Treg depletion adds to its efficacy but has wide-ranging implications for autoimmunity across multiple organ systems, similar to immune checkpoint inhibitor therapy. Occurrence of irAEs may be associated with improved overall clinical response, although long-term follow-up studies are needed.

Seborrheic dermatitis (SD) is a highly prevalent dermatological condition globally. The condition demonstrates bimodal presentation with what is commonly thought to be two subtypes: adult/adolescent seborrheic dermatitis (ASD) and infantile seborrheic dermatitis (ISD). Despite the common prevalence of ASD and ISD, there remains uncertainty around the underlying pathogenetic mechanisms, risk factors, and appropriate classification of the disease(s). This narrative review summarizes the current understanding of the epidemiology, presentation, and pathogenetic factors like epidermal barrier dysfunction, lipid abnormalities, and cutaneous microbiome for ASD and ISD. Elements such as immune responsiveness, neuroendocrine factors, and genetics in these disease states are also investigated. Throughout our review, we highlight shared features and discrepancies between ASD and ISD that are present in the literature and discuss potential avenues for future research that explore these disease states. We aim to contribute to the medical discourse on ASD and ISD and increase awareness of the need for additional research around these conditions, ultimately informing better targeting of therapeutics moving forward.
RESUMEN
The skin-lightening (SL) industry has a global reach and is projected to continue to grow over the coming decade. Although SL treatments may be safely prescribed for the treatment of some dermatologic conditions, many over-the-counter SL products contain ingredients that can cause harm to the skin and other organ systems. Given a lack of transparent information to patients and the historical colorist foundation that contextualizes a component of the cosmetic SL industry, dermatologists need to navigate biomedical and ethical concerns when explaining SL products to patients. This commentary briefly outlines the medical ethical issues surrounding this topic and describes avenues by which dermatologists may provide informed patient care that best supports beneficence, justice, autonomy, and nonmaleficence.
