Disseminated superficial actinic porokeratosis (DSAP) is an uncommon skin condition that can be inherited or may occur sporadically with multiple red-brown, thin plaques in a photodistribution. The condition more often affects middle-aged women and is often recalcitrant to therapy. In rare literature reports, systemic medications can trigger exacerbation or promote inflammation in pre-existing lesions of DSAP. Read More

Hydroxychloroquine and chloroquine, also known as antimalarial drugs, are widely used in the treatment of rheumatic diseases and have recently become the focus of attention because of the ongoing COVID-19 pandemic. Rheumatologists have been using antimalarials to manage patients with chronic immune-mediated inflammatory rheumatic diseases for decades. It is an appropriate time to review their immunomodulatory and anti-inflammatory mechanisms impact on disease activity and survival of systemic lupus erythematosus patient, including antiplatelet effect, metabolic and lipid benefits.

Many studies have investigated cutaneous reactions to antitumor drugs and found them to be quite numerous. We describe drug eruptions that may be associated with different therapies by class: antimetabolite chemotherapeutics, genotoxic agents, spindle inhibitors, signal transduction inhibitors, and immunotherapies. Methotrexate is most often associated with mucocutaneous reactions, alkylating antimetabolite agents with hyperpigmentation, and platinum antimetabolite agents with type I IgE-mediated hypersensitivity reactions.

Drug eruptions are among the great masqueraders that sometimes cause diagnostic challenges in clinical practice. Pharmacologic agents may induce skin changes, sharing the same pathophysiologic mechanisms of specific dermatoses, or inducing drug eruptions with different pathologic mechanisms that have similar clinical presentations. The former conditions are usually called drug-induced skin diseases, whereas the latter conditions are termed "dermatosis-like drug eruptions. Read More

Contact dermatitis (CD) refers to a group of cutaneous diseases caused by contact with allergens or irritants. It is characterized by different stages of an eczematous eruption and has the ability to mimic a wide variety of dermatologic conditions, including inflammatory dermatitis, infectious conditions, cutaneous lymphoma, drug eruptions, and nutritional deficiencies. Irritant CD and allergic CD are the two main presentations of the disease. Read More

Epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI) therapy is the primary treatment option for patients with non-small cell lung cancer (NSCLC). However, one of the major adverse effects associated with this therapy is skin toxicity, which impacts the patient's quality of life. This study aimed to describe the severities and locations of skin toxicity, and to analyze their association with the quality of life in patients with advanced NSCLC who received EGFR-TKI therapy as first-line treatment.

Dermatologic toxicities appear to be the most prevalent immunotherapy related adverse effects, both with anti-PD-1 and anti-CTLA-4 agents, as well as with the newly developed anti-PD-L1. They occur in more than one-third of the patients treated with immune check point inhibitors, regardless of the cancer being treated. They mainly manifest in the form of self-limiting maculopapular rashes and pruritus. Read More

Increased inflammatory cytokines [such as tumor necrosis factor alpha (TNFα) and interleukin-6 (IL-6)] are observed in COVID-19 patients, especially in the severe group. The phenomenon of a cytokine storm may be the central inducer of apoptosis of alveolar epithelial cells, which leads to rapid progression in severe group patients. Given the similarities of clinical features and pathogenesis between toxic epidermal necrolysis (TEN) and COVID-19, we hypothesize that the application of etanercept, an inhibitor of TNFα, could attenuate disease progression in severe group COVID-19 patients by suppressing systemic auto-inflammatory responses.

Background And Objectives: Treatment of severe dermatological autoimmune diseases and toxic epidermal necrolysis (TEN) with high-dose intravenous immunoglobulin (IVIg) is a well-established procedure in dermatology. As treatment with IVIg is usually considered for rare clinical entities or severe cases, the use of immunoglobulin is not generally based on data from randomized controlled trials usually required for evidence-based medicine. Since the indications for the use of IVIg are rare, it is unlikely that such studies will be available in the foreseeable future. Read More

Penicillin refers to a group of beta-lactam antibiotics that are the first-line treatment for a range of infections. However, they also possess the ability to form novel antigens, or neoantigens, through haptenation of proteins and can stimulate a range of immune-mediated adverse reactions - collectively known as drug hypersensitivity reactions (DHRs). IgE-mediated reactions towards these neoantigens are well studied, however, IgE-independent reactions are less well understood. Read More

The wide spectrum of the disease manifestations, long-term sequelae, and high mortality rates are a clinical concern. Though not commonly reported in spinal surgery patients, the use of long-term antibiotics is a potential causative agent in spinal infections. Read More

A severe cutaneous drug reaction resembling acute generalized exanthematous pustulosis resulting from ingestion of hydroxychloroquine has been documented. It is distinguishable by its longer incubation period, more varied morphology with initially urticarial and later targetoid and arcuate plaques, recalcitrance to therapy and longer duration. Given the anticipated surge in the use of hydroxychloroquine due to its reported benefits in those with coronavirus disease 2019, specific recognition of this entity is pivotal. Read More

Erythema nodosum (EN) is a form of septal panniculitis, which is believed to represent a delayed hypersensitivity reaction activated by infectious agents, drugs, granulomatous and autoimmune diseases, pregnancy, and malignancies. There are only four reported cases of EN during oral isotretinoin therapy to our knowledge, all of them occurring in patients with severe acne. Since acne itself can trigger EN, the question as to whether there is indeed a causative relationship between isotretinoin and EN in the reported cases remains to be elucidated. Read More

Immune checkpoint inhibitors (ICPi) have emerged as a new frontier of cancer therapy. Although monoclonal antibodies to cytotoxic T-lymphocyte associated protein 4 (CTLA-4), programmed cell death 1 (PD-1), and programmed cell death ligand 1 (PD-L1) have revolutionized oncologic management, these agents may result in a spectrum of immune-related adverse events (irAE) of which dermatologic toxicities are among the most frequent. Prompt recognition and management of irAE is essential for dermatologists caring for the expanding population of cancer patients exposed to these drugs. Read More

Toxic epidermal necrolysis (TEN) and Stevens-Johnson syndrome (SJS) are life-threatening, cutaneous reactions often associated with culprit drugs. A growing body of knowledge has deepened our understanding of the pathophysiology and clarified mechanisms such as drug-specific cytotoxicity mediated by T-cells, genetic linkage with HLA and non-HLA genes, TCR restriction, and cytotoxicity mechanisms. Physicians should broadly consider the etiology of SJS/TEN in order to better understand treatment strategies as well as identify which patients may be at risk for developing this condition.

We present the first detailed report of acneiform eruptions in patients on CTLA-4 inhibitor therapy. Acneiform eruptions commonly occur (up to 75-100%) as a cutaneous adverse event associated with EGFR inhibition; however, acneiform eruptions have not been highly reported as a cutaneous adverse event associated with CTLA-4 inhibitor therapy.
