RESUMEN
Cutaneous immune-related adverse events encompass a spectrum of dermatological manifestations, including lichenoid reactions, psoriasiform eruptions, eczematous dermatitis, immunobullous disorders, granulomatous reactions, pruritus, vitiligo, and severe cutaneous adverse reactions such as Stevens-Johnson syndrome. The conventional approach to treating high-grade or refractory cutaneous immune-related adverse events has involved high-dose systemic corticosteroids. However, their use is limited owing to the potential disruption of antitumor responses and associated complications. To address this, corticosteroid-sparing targeted immunomodulators have been explored as therapeutic alternatives. Biologic agents, commonly employed for non-cutaneous immune-related adverse events such as colitis, are increasingly recognized for their efficacy in treating various patterns of cutaneous immune-related adverse events, including psoriasiform, immunobullous, and Stevens-Johnson syndrome-like reactions. This review consolidates findings from the English-language literature, highlighting the use of biologic agents in managing diverse cutaneous immune-related adverse event patterns, also encompassing maculopapular, eczematous, and lichenoid eruptions, pruritus, and transient acantholytic dermatosis (Grover disease). Despite the established efficacy of these agents, further research is necessary to explore their long-term effects on antitumor responses.

Immune checkpoint inhibitors (ICIs) are effective antitumor agents but are associated with immune-related adverse events. ICI-induced psoriasis commonly presents in patients with a history of psoriasis but may occur de novo, and it has a significant physical and psychosocial impact. ICI-induced and non-ICI-induced psoriasis are likely mediated by similar cytokines, and similar treatments are employed. Topical treatment often suffices, and when needed, several systemic treatments appear to be effective without impacting antitumor response. Development of psoriasis may indicate a superior response to ICIs. Thus, recognition and management of ICI-induced psoriasis is essential to avoid ICI interruption and maximize therapeutic potential.

With an increasing number of patients eligible for immune checkpoint inhibitors, the incidence of immune-related adverse events (irAEs) is on the rise. Dermatologic immune-related adverse events (D-irAEs) are the most common and earliest to manifest, often with important downstream consequences for the patient. Current guidelines lack clarity in terms of diagnostic criteria for D-irAEs. The goal of this project is to better define D-irAE for the purposes of identification, diagnosis, and future study of this important group of diseases.The objectives of this project were to develop consensus guidance for an approach to D-irAEs including disease definitions and severity grading. Knowing that consensus among oncologists, dermatologists, and irAE subspecialists would be critical for usability, we formed a Dermatologic irAE Disease Definition Panel. The panel was composed of 34 experts, including oncologists, dermatologists, a rheumatologist, and an allergist/immunologist from 22 institutions across the USA and internationally. A modified Delphi consensus process was used, with two rounds of anonymous ratings by panelists and two virtual meetings to discuss areas of controversy. Panelists rated content for usability, appropriateness, and accuracy on 9-point scales in electronic surveys and provided free text comments. A working group aggregated survey responses and incorporated them into revised definitions. Consensus was based on numeric ratings using the RAND/UCLA Appropriateness Method with prespecified definitions.Following revisions based on panelist feedback, all items received consensus in the second round of ratings. Consensus definitions were achieved for 10 core D-irAE diagnoses: ICI-vitiligo, ICI-lichen planus, ICI-psoriasis, ICI-exanthem, ICI-bullous pemphigoid, ICI-Grover's, ICI-eczematous, ICI-eruptive atypical squamous proliferation, ICI-pruritus without rash, and ICI-erosive mucocutaneous. A standard evaluation for D-irAE was also found to reach consensus, with disease-specific exceptions detailed when necessary. Each disorder's description includes further details on disease subtypes, symptoms, supportive exam findings, and three levels of diagnostic certainty (definite, probable, and possible).These consensus-driven disease definitions standardize D-irAE classification in a useable framework for multiple disciplines and will be the foundation for future work. Given consensus on their accuracy and usability from a representative panel group, we anticipate that they can be used broadly across clinical and research settings.

Dermatologic adverse events resulting from oncologic therapy are common and negatively impact patients' quality of life. Dermatologic adverse events include toxicity of the skin, oral mucosa, nails, and hair and are seen with cytotoxic chemotherapy, targeted therapy, immunotherapy, and radiation therapy, with distinct patterns of dermatologic adverse events by drug class. Here, we review the literature on the impact of dermatologic adverse events on quality of life. Studies on quality of life in patients with cancer have relied on scales such as the Dermatologic Life Quality Index and Skindex to demonstrate the association between dermatologic adverse events and declining quality of life. This relationship is likely due to a variety of factors, including physical discomfort, changes to body image, decreased self-esteem, and an effect on social interactions. Addressing such quality-of-life concerns for patients with cancer is critical, not only for patients' well-being but also because decreased satisfaction with treatment can lead to discontinuation of treatment or dose reduction. Prophylactic treatment and early management of dermatologic adverse events by experienced dermatologists can alleviate the negative effects on quality of life and allow continuation of life-prolonging treatment.

PURPOSE: Cutaneous adverse effects from cyclin-dependent 4 and 6 kinase inhibitors (CDK4/6i) used in metastatic breast cancer are prevalent and well described. Vitiligo-like lesions have been reported and are rare. They can negatively impact patients' quality of life and may be associated with survival benefits. We describe the clinical characteristics of vitiligo-like lesions in an international cohort of patients treated with CDK4/6i to help improve recognition and management. METHODS: Retrospective review of patients diagnosed with vitiligo-like lesions from CDK4/6i from five academic institutions in the USA and Europe was performed. Ten patients were included in the study. RESULTS: Median age of our patients was 55 (range 37-86). Median progression-free survival was 24 months in 5 patients. The median time to rash was 10 months. Sun-exposed areas such as the arms and face were the most affected areas. Multiple skin-directed therapies such as topicals, laser, and phototherapy were trialed with minor success. Mild repigmentation was seen in one patient treated with ruxolitinib cream. CDK4/6 treatment was discontinued due to the vitiligo-like lesions in one patient. CONCLUSION: Clinical characteristics are similar to previously reported findings in case reports and series. We add topical ruxolitinib as a potential treatment option for these patients and include data regarding progression-free survival that should continue to be collected. No definitive conclusions can be made regarding survival benefits from our cohort. Clinicians should refer these patients to dermatologists to aid with management.

BACKGROUND: Xylazine is an α 2 -adrenergic agonist that is commonly used as a veterinary tranquilizer and is increasingly present in the unregulated US drug supply since at least 2019. There are many suspected clinical complications of xylazine use, including unusual skin wounds, atypical overdose presentations, and possible dependence and withdrawal syndromes. However, there are few reports of cutaneous manifestations of xylazine in patients who inject drugs that can guide diagnosis and management in patients with confirmed xylazine toxicology. CASE SUMMARY: We present the cases of 3 stably housed patients in Connecticut with opioid use disorder and intravenous use of fentanyl who presented with atypical, chronic wounds at the site of injection drug use. Xylazine toxicology sent on all 3 patients was positive. All patients were seen by wound care and dermatology, and 1 patient was followed by infectious diseases. Wound care management strategies are discussed as well as harm reduction strategies. For all patients, the dose of their medication for opioid use disorder was increased to decrease frequency of drug use given concern that patients were exposed to a drug supply containing xylazine. CLINICAL SIGNIFICANCE: This case report presents wound characteristics that raise the index of suspicion for xylazine-involved injection wounds and might assist in their diagnosis and management. There is urgent need for more reporting of such cases as well as rigorous research to understand the potential impact of xylazine on people who use drugs. Multidisciplinary best practices should be established.

BACKGROUND: In 2023, nearly 2 million patients will be diagnosed with cancer in the United States and at least 40% will be eligible for treatment with an immune checkpoint inhibitor (ICI). Cutaneous immune related adverse events (cirAEs) from ICIs are common and include pruritus as well as maculopapular, eczematous, bullous, lichenoid, and psoriasiform reactions. All clinicians interfacing with cancer patients must expedite proper evaluation and diagnosis, treatment, and/or consultation that supports the need for evidence-directed guidelines. MATERIALS AND METHODS: A panel of advisors was selected, and a systematic literature review generated foundational evidence to develop a treatment algorithm for cirAEs via a modified Delphi process. Iterations of the algorithm were performed until the group met consensus. RESULTS: An algorithm that tailors the management of cirAEs was developed based on the CTCAE v.5 grading of skin disorders. Representative clinical images and suggested diagnostic measures, supplement the algorithm. CONCLUSION: Recognition and treatment of cirAEs guided through a multidisciplinary, physician-developed algorithm will limit disruption of immunotherapy, optimize quality of life, and enhance overall outcomes in patients treated with ICIs.

The diagnosis of scabies can be difficult when the infection presents as erythroderma. Crusted scabies is a severe form of scabies caused by cutaneous ectoparasitic infection by the mite Sarcoptes scabiei var hominis. Crusted scabies most commonly occurs in patients with underlying immunosuppression from acquired infection or subsequent to solid organ or bone marrow transplantation. We present a rare case of a patient with granulomatosis with polyangiitis (GPA) who developed azathioprine-induced myelosuppression and subsequent erythrodermic crusted scabies. It is critical to maintain a broad differential when patients present with erythroderma, especially in the setting of medication-induced immunosuppression for the treatment of autoimmune disease.

The peripheral T cell repertoire of healthy individuals contains self-reactive T cells1,2. Checkpoint receptors such as PD-1 are thought to enable the induction of peripheral tolerance by deletion or anergy of self-reactive CD8 T cells3-10. However, this model is challenged by the high frequency of immune-related adverse events in patients with cancer who have been treated with checkpoint inhibitors11. Here we developed a mouse model in which skin-specific expression of T cell antigens in the epidermis caused local infiltration of antigen-specific CD8 T cells with an effector gene-expression profile. In this setting, PD-1 enabled the maintenance of skin tolerance by preventing tissue-infiltrating antigen-specific effector CD8 T cells from (1) acquiring a fully functional, pathogenic differentiation state, (2) secreting significant amounts of effector molecules, and (3) gaining access to epidermal antigen-expressing cells. In the absence of PD-1, epidermal antigen-expressing cells were eliminated by antigen-specific CD8 T cells, resulting in local pathology. Transcriptomic analysis of skin biopsies from two patients with cutaneous lichenoid immune-related adverse events showed the presence of clonally expanded effector CD8 T cells in both lesional and non-lesional skin. Thus, our data support a model of peripheral T cell tolerance in which PD-1 allows antigen-specific effector CD8 T cells to co-exist with antigen-expressing cells in tissues without immunopathology.
