Abstract
BACKGROUND Cutaneous adverse events (CAEs) related to oncological therapies are a common scenario in daily clinical practice. METHODS This is a retrospective observational study collecting the data regarding CAEs of patients treated with immune checkpoints inhibitors (ICIs) in four different Italian centers. RESULTS Of 323 patients included, 305 were evaluable for this analysis; 182 patients (59.7%) had metastatic cutaneous melanoma (CM), 99 (32.5%) non-small cell lung cancer (NSCLC) and 24 (7.8%) renal cell carcinoma (RCC). The most frequent CAEs that we found, considering all the 305 patients, were pruriginous maculopapular rash (10.2% of the patients), vitiligo-like areas (7.2% of the patients), psoriasiform rash (6.2% of the patients), asymptomatic maculopapular rash (4.6% of the patients), and lichenoid rash (4.3% of the patients). Vitiligo-like areas occurred more frequently in patients with CM, while a lichenoid rash was more frequently observed in patients with RCC. Treatment interruption was related to drug-induced CAEs in 15.4% of melanoma patients and 0.0% of lung and kidney patients. Patients developing a cutaneous adverse event had better overall response rate and higher progression free survival and overall survival than the patients without CAEs. CONCLUSIONS Our study brings new information on the characteristics of CAEs related to ICIs treatment in three different types of cancers, CM, NSCLC and RCC.

Transcriptional profiling of rare acantholytic disorders suggests common mechanisms of pathogenesis. JCI Insight 2023; 8:e168955.

Abstract
Darier, Hailey-Hailey, and Grover diseases are rare acantholytic skin diseases. While these diseases have different underlying causes, they share defects in cell-cell adhesion in the epidermis and desmosome organization. To better understand the underlying mechanisms leading to disease in these conditions, we performed RNA-seq on lesional skin samples from patients. The transcriptomic profiles of Darier, Hailey-Hailey, and Grover diseases were found to share a remarkable overlap, which did not extend to other common inflammatory skin diseases. Analysis of enriched pathways showed a shared increase in keratinocyte differentiation, and a decrease in cell adhesion and actin organization pathways in Darier, Hailey-Hailey, and Grover diseases. Direct comparison to atopic dermatitis and psoriasis showed that the downregulation in actin organization pathways was a unique feature in the acantholytic skin diseases. Furthermore, upstream regulator analysis suggested that a decrease in SRF/MRTF activity was responsible for the downregulation of actin organization pathways. Staining for MRTFA in lesional skin samples showed a decrease in nuclear MRTFA in patient skin compared with normal skin. These findings highlight the significant level of similarity in the transcriptome of Darier, Hailey-Hailey, and Grover diseases, and identify decreases in actin organization pathways as a unique signature present in these conditions.

Cutaneous Side Effects of Modern Targeted Therapy and Immunotherapy in Patients with Dermatological Malignancies. Cancers (Basel) 2023; 15:3126. [PMID: 37370736 DOI: 10.3390/cancers15123126] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2023] [Revised: 05/24/2023] [Accepted: 06/07/2023] [Indexed: 06/29/2023] Open
Abstract
The advent of immunotherapy and targeted therapies in treating dermatological malignancies has dramatically changed the landscape of dermato-oncology in recent years. Their superior efficacy compared to previous therapeutic options, such as chemotherapy, has resulted in their use in treating devastating malignancies, such as melanoma or unresectable/metastatic basal cell and squamous cell carcinoma. Skin toxicity is a critical safety consideration, among other adverse reactions, that can occur under treatment with these agents. This article aims to summarize the cutaneous side effects of immune checkpoint inhibitors and targeted dermato-oncological therapies. Although the skin side effects of these agents are primarily mild, they can occasionally affect the decision for treatment continuation and the quality of life of the affected patients. Therefore, physicians must be acquainted with the specific cutaneous toxicity profile of such treatments to mitigate their impact on the patients and optimize the overall outcome of dermato-oncological therapy.

Immune-Related Uncommon Adverse Events in Patients with Cancer Treated with Immunotherapy. Diagnostics (Basel) 2022; 12:diagnostics12092091.

Abstract
Immunotherapy has dramatically changed the therapeutic landscape of oncology, and has become standard of care in multiple cancer types in front or late lines of therapy, with some longstanding responses and outstanding results. Notwithstanding, its use has brought a totally unique spectrum of adverse events, characterized by a myriad of diverse manifestations affecting nearly every organ and system of the body, including the endocrine, nervous, cardiac, respiratory and gastrointestinal systems. Uncommon adverse events, defined as those occurring in less than 1% of patients, comprise an even more heterogeneous group of diseases that are being seen more recurrently as the use of immune check-point inhibitors increases and indications spread in different tumor types and stages. Here, we comprehensively review some uncommon, but exceedingly important, immune-related adverse events, with special emphasis in the clinical approach and diagnostic workup, aiming to reunite the evidence published previously, allowing an increase in awareness and knowledge from all specialists implicated in the diagnosis, treatment, and care of cancer patients treated with immunotherapy.

Abstract
In accordance with recent therapeutic progress of immune checkpoint inhibitors for certain cancers, various disorders are induced as immune-related adverse events (irAEs) affecting the skin, gut, thyroid gland, lung, and liver. Among such irAEs, mucocutaneous manifestation is the most common. Cutaneous manifestations are categorized into several groups, ie, inflammatory reactions, immunobullous reactions, alterations of epidermal keratinocytes, and alterations of epidermal melanocytes; however, there are additionally various cutaneous toxicities, unclassified into those groups. Blocking of programmed cell death 1 (PD-1)/programmed cell death ligand 1(PDL1) can lead to the induction of autoimmune reaction, via activation of cytotoxic T cells, inhibition of regulatory T cell function, and alteration of cytokine balance. Similarly, blockade of cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4) reduces the suppressive function of regulatory T cells. Due to those mechanisms, various autoimmune conditions can be induced, in addition to nonspecific drug eruptions. Dermatologists should be aware of various types of those mucocutaneous manifestations, either common or rare, as well as the management of such conditions. Herein, various mucocutaneous manifestations of irAEs and cases involving Japanese patients have been described, based on a single institute's experience.

Abstract
Immune checkpoint inhibitors have shown efficacy in the treatment of different cancers by stimulating the antitumoral activity of the patient’s immune system, representing a major breakthrough in the field of cancer therapy. Monoclonal antibodies including anti-cytotoxic T-lymphocyte–associated protein 4, anti–programmed cell death protein 1 and its ligand inhibitors have been approved for advanced melanoma among other solid cancers. Although immunotherapy demonstrated a good safety profile, a new spectrum of multisystemic immune-related adverse events has been recently reported due to their use. Cutaneous reactions represent one of the leading adverse events, often reported in literature as “skin rash”, and rarely further characterized in distinct dermatologic entities. Herein we describe the distinctive cutaneous rashes occurring during immunotherapies for advanced melanoma, discussing implications in the treatment management.

Abstract
Immune checkpoint inhibitors (ICIs) cause a variety of inflammatory eruptions. The understanding of ICI-induced inflammatory eruptions with detailed histopathological findings is not adequate, particularly in Asian populations. In this study, we retrospectively reviewed 51 patients who were histopathologically diagnosed with cutaneous immune-related adverse events (irAEs) following ICI therapy between 2014 and 2020 at the Department of Dermatology of Kyushu University Hospital. Of the 51 patients (30 men, 21 women), maculopapular rash (38/51, 74.5%), erythema multiforme (2/51, 3.9%), lichenoid reaction (3/51, 5.9%), psoriasiform reaction (3/51, 5.9%), bullous pemphigoid (3/51, 5.9%), scleroderma-like reaction (1/51, 2.0%), and Stevens–Johnson syndrome (1/51, 2.0%) were observed. The clinical and histopathological findings of these eruptions were equivalent to typical cases of common drug eruptions. The onset of maculopapular rash was relatively early (more than half of events occurred within 1 month), whereas lichenoid reactions and autoimmune diseases occurred relatively late (4–8 months). With appropriate treatment and/or interruption of ICIs, most rashes improved (50/51, 98.0%). The ICI-induced inflammatory eruptions shared similar clinical and histopathological features with classical inflammatory eruptions, but a variety of inflammatory eruptions may occur with different degrees of severity. Dermatologists play an important role in providing specialized care for cutaneous irAEs.

Abstract
Immune checkpoints assist with self-tolerance and minimize collateral tissue damage when immune responses are activated. Although immune checkpoint inhibitors (CPIs) are characterized by a favorable risk/benefit ratio, immune checkpoint blockade has been associated with a new subset of autoimmune-like toxicities, named immune-related adverse events (irAEs). Dermatologic reactions are among the most prevalent irAEs triggered by CPIs. In a majority of cases they are self-limiting and readily manageable. However, it is not uncommon that they result in severe skin involvement and impairment of patients' quality of life. Awareness of the spectrum of cutaneous irAEs is mandatory for every clinician involved in the management of oncologic patients. The role of the dermatologists is essential because early recognition and appropriate management of skin toxicity may prevent dose modifications and discontinuation of CPIs. The latter is particularly relevant, considering that recent data suggest favorable oncologic response in patients developing irAEs.

Abstract
Grover's disease (GD) is an itchy acantholytic disorder occurring on the trunk of middle-aged men. Based on the best evidence, this study aimed to provide a summary of the clinical characteristics, disease course and treatments of GD. A systematic review was performed according to PRISMA guidelines for original articles published between 01.01.1970-08.15.2019, assessing clinical features and/or any type of intervention for GD. A total of 263 articles were retrieved, and 116 original reports that were deemed relevant and satisfied the inclusion criteria were included in the analysis (88 case reports, 26 case series and two retrospective reviews). From these articles, 317 patients were identified, with a male-to-female ratio of 3.95. The mean age was 59 years (range 11-92). Typical lesions were itchy papules and vesicle-papules, generally located on the trunk. Spontaneous resolution within one week to eight months was described in 42 % of cases. Topical corticosteroids (TCSs) were the most frequent treatment (response rate of 70 %) followed by systemic retinoids and corticosteroids with response rates of 86 % and 64 %, respectively. According to the results of this review, TCS appears to be the most frequently employed treatment, and we suggest TCS as first-line therapy. Second-line treatments could include systemic retinoids or systemic corticosteroids.

Abstract
Antineoplastic agents that use the immune system have revolutionized cancer treatment. Specifically, implementation of immune checkpoint inhibitors, monoclonal antibodies that block cytotoxic T-lymphocyte-associated antigen-4, programmed cell death protein 1, or programmed cell death ligand 1 show improved and sustained responses in patients with cancer. However, these agents are associated with a plethora of adverse events, many manifesting in the skin. As the clinical application of cancer immunotherapies expands, understanding the clinical and histopathologic features of associated cutaneous toxicities becomes increasingly important to dermatologists, oncologists, and pathologists to ensure timely diagnosis and appropriate care. This review discusses cutaneous reactions to immune checkpoint inhibitors, focusing on histopathologic features.

Abstract
Grover disease (GD) is a benign eruption that causes a papulovesicular rash on the trunk and proximal extremities. It often resolves spontaneously but can follow a more chronic and fluctuating course that may last several years. Although the etiology remains unknown, several associated triggers have been identified including heat and sweating, cool and dry air, renal failure, malignancy, and the initiation of several drugs. Since the disease tends to resolve on its own, management is aimed at disease prevention and symptomatic relief. First-line therapy includes topical steroids and vitamin D analogues with adjuvant antihistamines. In more severe cases that are refractory to less aggressive therapy, systemic corticosteroids, retinoids, and phototherapy may lead to successful resolution. Novel therapies are few and have little evidence but involve innovative use of light therapy and immune modulators. Herein, we review the literature and new trends of GD with a focus on established and novel treatments.

Abstract
Background:The introduction of Immune Checkpoint Inhibitors in the recent years has resulted in high response rates and extended survival in patients with metastatic/advanced malignancies. Their mechanism of action is the indirect activation of cytotoxic T-cells through the blockade of inhibitory receptors of immunomodulatory pathways, such as cytotoxic T-lymphocyte-associated antigen-4 (CTLA-4), programmed cell death protein-1 (PD-1) and its ligand (PD-L1). Despite their impressive therapeutic results, they can also induce immune-related toxicity, affecting various organs, including the skin.Objective:To provide an updated summarized overview of the most common immune-mediated cutaneous side effects and their management.Method:English articles derived from the databases PubMed and SCOPUS and published between 2009 and 2018, were analyzed for this narrative review.Results:The most common adverse cutaneous reactions include maculopapular rash, lichenoid reactions, vitiligo and pruritus, with severity Grade 1 or 2. Less frequent but eventually life-threatening skin side effects, including Stevens-Johnson syndrome, Drug Reaction with Eosinophilia and Systemic Symptoms and Toxic Epidermal necrolysis, have also been reported.Conclusion:Basic knowledge of the Immune-Checkpoint-Inhibitors-induced skin toxicity is necessary in order to recognize these treatment-related complications. The most frequent skin side effects, such as maculopapular rash, vitiligo and pruritus, tend to subside under symptomatic treatment so that permanent discontinuation of therapy is not commonly necessary. In the case of life-threatening side effects, apart from the necessary symptomatic treatment, the immunotherapy should be permanently stopped. Information concerning the management of ICIs-mediated skin toxicity can be obtained from the literature as well as from the Summary of Product Characteristics of each agent.

Suprabasal acantholytic dermatologic toxicities associated checkpoint inhibitor therapy: A spectrum of immune reactions from paraneoplastic pemphigus-like to Grover-like lesions.

Abstract
Checkpoint inhibitors (CPIs) restore the function of effector immunocytes to target and destroy cancer cells. Immune-related adverse events (irAEs) are a consequence of immune reactivation, with unpredictable inflammatory response, loss of self-tolerance, and development of autoimmunity. Adverse events from CPIs that present as dermatologic toxicities have diverse clinical and histopathologic features. CPI-associated dermatologic toxicities may exhibit histopathologic features of lichenoid dermatitis, bullous pemphigoid, and granulomatous/sarcoid-like reactions. Suprabasal acantholytic dermatologic toxicities associated with CPIs are particularly rare but represent an emerging histopathologic pattern and include lichenoid dermatitis with suprabasal acantholysis/vesicle formation to Grover disease (transient acantholytic dermatosis). Here, we report two patients who developed suprabasal acantholytic dermatologic toxicities during CPI therapy. One patient exhibited a CPI-associated autoimmune blistering disease with paraneoplastic pemphigus (PNP)-like features restricted to histopathology and immunofluorescence, while the other patient had Grover-like lesions. A review of the literature revealed a spectrum of suprabasal acantholytic dermatologic toxicities associated CPIs that may present as lichenoid dermatitis with acantholysis/vesicle formation, Grover-like eruptions, and lesions with PNP-like features restricted to histopathology and immunofluorescence. It is important for clinicians and pathologists to recognize the types of dermatologic toxicities associated with CPIs to direct appropriate therapeutic strategies.

Abstract
The development of immune checkpoint inhibitors [monoclonal antibodies targeting cytotoxic T lymphocyte-associated antigen-4 (CTLA-4), programmed cell death protein 1 (PD-1) or programmed death ligand 1 (PD-L1)] represents a major breakthrough in cancer therapy. Although they present a favorable risk/benefit ratio, immune checkpoint blockade therapies have a very specific safety profile. Due to their unique mechanism of action, they entail a new spectrum of adverse events that are mostly immune related [immune-related adverse events (irAEs)], notably mediated by the triggering of cytotoxic CD4+/CD8+ T cell activation. Cutaneous toxicities appear to be one of the most prevalent irAEs, both with anti-PD-1 and anti-CTLA-4 agents or with the newly developed anti-PD-L1 agents, which corresponds to a class effect. They are observed in more than one-third of the treated patients, mainly in the form of a maculopapular rash (eczema-like spongiotic dermatitis) and pruritus. A wide range of other dermatologic manifestations can also occur, including lichenoid reactions, psoriasis, acneiform rashes, vitiligo-like lesions, autoimmune skin diseases (e.g., bullous pemphigoid, dermatomyositis, alopecia areata), sarcoidosis or nail and oral mucosal changes. In addition, the use of anti-CTLA-4 and anti-PD-1 therapies in combination is associated with the development of more frequent, more severe and earlier cutaneous irAEs compared to single agents. In most cases, these dysimmune dermatologic adverse events remain self-limiting and readily manageable. Early recognition and adequate management, however, are critical to prevent exacerbation of the lesions, to limit treatment interruption and to minimize quality of life impairment. This review describes the variable clinical and histopathologic aspects of dermatologic irAEs induced by immune checkpoint inhibitors. Appropriate treatment and counseling are also proposed, with a step-by-step approach for optimized management by both practicing oncologists and dermatologists.

Abstract
New drugs against advanced melanoma have emerged during last decade. Target therapy and immunotherapy have changed the management of patients with metastatic disease. Along with its generalized use, drug toxicities have appeared and the skin is the target organ of a significant part of them. This revision summarizes the most common side effects and consensus management to improve the compliance of therapies and patients' quality of life. Among the BRAF inhibitors, main cutaneous side effects are photosensitivity, plantar hyperkeratosis, and the appearance of verrucal keratosis or squamous cell carcinoma. Special attention must be paid to the development of new primary melanomas or changes on nevi during BRAF inhibitor therapy. The most common cutaneous side effects of immunotherapy are rash, pruritus, and vitiligo. It remains controversial the possible role of these toxicities as markers of response to therapy.

Abstract
The development of immune checkpoint inhibitors (monoclonal antibodies targeting PD-1/PD-L1 or CTLA-4) represents a significant advance in the treatment of multiple cancers. Given their particular mechanism of action, which involves triggering CD4+/CD8+ T-cell activation and proliferation, they are associated with a specific safety profile. Their adverse events are primarily immune-related, and can affect practically all organs. In this context, dermatological toxicity is the most common, though it mostly remains mild to moderate and does not require discontinuation of treatment. More than a third of patients are faced with cutaneous adverse events, usually in the form of a maculopapular rash, pruritus or vitiligo (only in patients treated for melanoma). Much more specific dermatologic disorders, however, may occur such as lichenoid reactions, induced psoriasis, sarcoidosis, auto-immune diseases (bullous pemphigoid, dermatomyositis, alopecia areata), acne-like rash, xerostomia, etc. Rigorous dermatological evaluation is thus mandatory in the case of atypical, persistent/recurrent or severe lesions. In this article, we review the incidence and spectrum of dermatologic adverse events reported with immune checkpoint inhibitors. Finally, a management algorithm is proposed.

Atypical features and systemic associations in extensive cases of Grover disease: A systematic review. J Am Acad Dermatol 2017; 77:952-957.e1. [PMID: 28918973 DOI: 10.1016/j.jaad.2017.06.041] [Citation(s) in RCA: 31] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/27/2017] [Revised: 06/13/2017] [Accepted: 06/17/2017] [Indexed: 11/28/2022]
Abstract
BACKGROUND Grover disease is an acantholytic disorder that typically occurs on the trunk of older individuals, primarily white men, in association with heat and xerosis. Cases with extensive and/or atypical distributions have been reported. OBJECTIVE To review the literature characterizing the population, morphology, associations, and disease course of extensive or atypical eruptions of Grover disease. METHODS A systematic literature review identified 50 articles with 69 cases. RESULTS Patient age ranged from 14 to 83 years (mean age, 56 ± 15), with 71% of patients being male and 29% female. Areas of involvement included the trunk (90%), upper and lower extremities (63% and 61%, respectively), face/scalp (28%), neck (21%), groin (11%), buttocks (8%), and axillae (6%). The most common associations included a history of malignancy (61%), recent chemotherapy (38%), and recent transplant (20%). LIMITATIONS Extensive cases with typical clinical morphology may not have been examined by biopsy or reported; thus, this review may have publication bias toward more severe or atypical presentations. CONCLUSIONS Greater variability exists among patients affected by extensive or atypical Grover disease than among those with typical disease. Malignancy is a common association, and there may be a role for immunosuppression in the pathogenesis of extensive or atypical Grover disease.

Histopathological aspects of cutaneous erythematous-papular eruptions induced by immune checkpoint inhibitors for the treatment of metastatic melanoma. Int J Dermatol 2017; 56:527-533. [PMID: 28188628 DOI: 10.1111/ijd.13540] [Citation(s) in RCA: 24] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/19/2016] [Revised: 10/06/2016] [Accepted: 11/29/2016] [Indexed: 12/25/2022]
Abstract
BACKGROUND Immune checkpoint blockade therapy (ICBT) for the treatment of melanoma has led to an important improvement of overall survival in advanced stage patients. However, secondary cutaneous maculopapular eruptions (CMPEs) are frequent and remain poorly characterized. METHODS We performed a retrospective analysis of melanoma patients from our institution who developed CMPEs during ICBT. Clinical information was retrieved, and histopathological and immunohistochemical characterization was performed by two pathologists. For comparison, a group of biopsies from CMPE caused by anti-v-raf murine sarcoma viral oncogene homolog B1 (BRAF) therapy was analyzed. RESULTS Eleven patients met the inclusion criteria. On clinical grounds, CMPE developed mainly on early onset of immunotherapy and were of low grade. Typical lesions included erythematous papules and macules affecting the trunk and/or extremities with associated pruritus. The histopathological patterns consisted of a superficial perivascular lymphocytic dermatitis (SPLD) with eosinophils followed by a granulomatous dermatitis. Other patterns included lichenoid, spongiotic, and a case of Grover's disease. The inflammatory infiltrate consisted of T lymphocytes (CD3+ ) with a predominance of CD4+ over CD8+ cells; isolated Foxp3+ cells were invariably present, and PD-1 was not expressed. Biopsies from CMPE caused by anti-BRAF therapy showed an SPLD and a similar lymphocytic immunophenotype. CONCLUSIONS Our study showed the clinical features of a group of melanoma patients with CMPE for ICBT and emphasized the wide spectrum of histological findings as well as their immunohistochemical profile. Differential diagnosis can be difficult with CMPE provoked by other therapies as was seen in our comparison group of anti-BRAF-induced eruptions.

Diverse types of dermatologic toxicities from immune checkpoint blockade therapy. J Cutan Pathol 2016; 44:158-176. [PMID: 27859479 DOI: 10.1111/cup.12858] [Citation(s) in RCA: 160] [Impact Index Per Article: 20.0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2016] [Revised: 11/03/2016] [Accepted: 11/06/2016] [Indexed: 12/28/2022]
Abstract
Immunomodulatory drugs that leverages host immune mechanisms to destroy tumor cells have been met with great promise in the treatment of cancer. Immunotherapy, targeting cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4) and the programmed cell death 1 (PD-1) receptor and its ligand (PD-L1) have shown tremendous improvements in the survival of patients with advanced solid tumors. However, the development of dermatologic toxicity (DT) is a consequence to immunotherapy. Review of published reports of the DT to immunotherapy revealed patients receiving anti-CTCLA-4 antibody or anti-PD-1/PD-L1 antibody often develop a DT of any type and grade. In this article, of the 3825 patients who were treated with anti-PD-1 and of 556 patients receiving anti-PD-L1, DT of any type and grade were reported in 1474 (∼39%) and 95 (∼17%) of patients, respectively. The emergence of specific types of DT to immunotherapy is beginning to be recognized can be categorized into four groups: (a) inflammatory, (b) immunobullous, (c) alteration of keratinocytes and (d) alteration of melanocytes. Lichenoid dermatitis and bullous pemphigoid appear to be DT more associated with anti-PD-1/PD-L1 antibody. The DT profile in patients receiving immunotherapy is diverse, and early recognition of specific types of DT that clinicians may encounter is critical for optimal patient care.

Abstract
Immune checkpoint inhibitors (ICI) represent a new revolutionary weapon in the armamentarium of anti-cancer therapies. The side effects of these new agents represent a new challenge for oncologists; they are usually unpredictable and sometimes life threatening, if not managed rapidly and adequately. The most frequent side effects are the dermatologic, but they are usually low grade side effects and consequently easily manageable. Rash, pruritus and vitiligo are the most frequent dermatologic side effects. We aimed in this review to describe first all the dermatologic side effects of ICI according to the subtype of ICI and combination therapies in the clinical trials, then to report all the rare case reports dermatologic side effects, and finally to present the management algorithm of these side effects.

Abstract
Background Immune related adverse events (irAEs) are common side effects of checkpoint inhibitory (CPI) therapies targeting CTLA-4 and PD-1/PD-L1. Grover’s disease is an uncommon dermatologic condition with unclear pathogenesis previously reported as an irAE with ipilimumab. Case Presentation We report an additional case of ipilimumab-induced Grover’s disease. Interestingly, this dermatologic side effect did not appear with use of anti-PD-1 therapy in our patient. Immune analysis was performed and suggests a possible role of Th2 cells in its patholgenesis. Conclusion This case suggests that Grover's disease is an irAE induced by Ipilimumab. Our immune analysis suggests that Th2 cells may be pathogenic mediators which warrants further study.

Abstract
Background Dermatologic toxicity is an important adverse effect of immune checkpoint inhibitors targeting cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4) and programmed cell death 1 receptor (PD-1) or PD ligand 1 (PD-L1). Skin toxicity most commonly includes a maculopapular erythematous rash and pruritus. Rarely life threatening complications such as Steven’s Johnson syndrome or toxic epidermal necrolysis may occur. Case presentation Here we report the uncommon event of a drug-induced transient acantholytic dermatosis (Grover’s disease) in a 73-year-old Caucasian male treated with ipilimumab for metastatic melanoma. Five weeks after initiation of therapy, the patient developed a widespread polymorphic papulovesicular dermatosis on the trunk and proximal extremities with intense pruritus. Skin biopsy showed acantholytic dyskeratosis with interface dermatitis consistent with a Grover’s-like drug eruption. Conclusions These findings should raise awareness for uncommon immune-related dermatological toxicities of immunomodulatory antibodies targeting the CTLA-4 signaling axis. We recommend biopsies of unexpected skin lesions to rapidly identify dermatological adverse events of immune checkpoint inhibitors.

Abstract
INTRODUCTION The treatment of melanoma is evolving rapidly over the past few years. Patients with BRAFv600 mutations can be treated with a combination of a BRAF-inhibitor and an MEK-inhibitor. Patients with BRAF wild-type tumors and BRAFv600 mutated tumors can be treated with immunotherapy i.e. check point inhibitors. AREAS COVERED We conducted a comprehensive review of the literature on the efficacy and predictive markers, safety, and pharmacoeconomics of ipilimumab in melanoma Expert commentary: Ipilimumab was the first check point inhibitor reaching the clinic, gaining FDA and EMA approval for metastatic melanoma in 2011. Ipilimumab was also approved by FDA in the adjuvant setting for patients with high risk, stage III melanoma. The anti-PD1 directed antibodies pembrolizumab and nivolumab are superior to single agent ipilimumab, which is no longer considered the standard first line treatment in metastatic melanoma. The addition ipilimumab to nivolumab is associated with a higher response rate and a better PFS, particularly in patients with PD-L1 negative tumors, albeit at the cost of a steep increase in grade 3-4 adverse event rate. Definitive survival data on this combination are pending and the selection of patients potentially requiring the combination and its pharmacoeconomic implications are to be elucidated.

Immune related adverse events associated with anti-CTLA-4 antibodies: systematic review and meta-analysis. BMC Med 2015; 13:211. [PMID: 26337719 PMCID: PMC4559965 DOI: 10.1186/s12916-015-0455-8] [Citation(s) in RCA: 483] [Impact Index Per Article: 53.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/22/2015] [Accepted: 08/18/2015] [Indexed: 02/08/2023] Open
Abstract
BACKGROUND Targeting CTLA-4 is a recent strategic approach in cancer control: blocking CTLA-4 enhances an antitumor immunity by promoting T-cell activation and cytotoxic T-lymphocyte proliferation. This induction of a tolerance break against the tumor may be responsible for immune-related adverse events (irAEs). Our objective was to assess the incidence and nature of irAEs in oncologic patients receiving anti-CTLA-4 antibodies (ipilimumab and tremelimumab). METHODS A systematic search of literature up to February 2014 was performed in MEDLINE, EMBASE, and Cochrane databases to identify relevant articles. Paired reviewers independently selected articles for inclusion and extracted data. Pooled incidence was calculated using R(©), package meta. RESULTS Overall, 81 articles were included in the study, with a total of 1265 patients from 22 clinical trials included in the meta-analysis. Described irAEs consisted of skin lesions (rash, pruritus, and vitiligo), colitis, and less frequently hepatitis, hypophysitis, thyroiditis, and some rare events such as sarcoidosis, uveitis, Guillain-Barré syndrome, immune-mediated cytopenia and polymyalgia rheumatic/Horton. The overall incidence of all-grade irAEs was 72 % (95 % CI, 65-79 %). The overall incidence of high-grade irAEs was 24 % (95 % CI, 18-30 %). The risk of developing irAEs was dependent of dosage, with incidence of all-grade irAEs being evaluated to 61 % (95 % CI, 56-66 %) for ipilimumab 3 mg/kg and 79 % (95 % CI, 69-89 %) for ipilimumab 10 mg/kg. Death due to irAEs occurred in 0.86 % of patients. The median time of onset of irAEs was about 10 weeks (IQR, 6-12) after the onset of treatment, corresponding with the first three cycles but varied according to the organ system involved. Such immune activation could also be indicative for tumor-specific T-cell activation and irAE occurrence was associated with clinical response to CTLA-4 blocking in 60 % of patients. CONCLUSION The price of potential long-term survival to metastatic tumors is an atypical immune toxicity, reflecting the mechanism of action of anti-CTLA-4 antibodies. A better knowledge of these irAEs and its management in a multidisciplinary approach will help to reduce morbidity and therapy interruptions.

Abstract
BACKGROUND Acantholytic dyskeratosis under BRAF inhibitors are dermatological diseases rarely reported to date. PATIENTS AND METHODS We report 2 cases of acantholytic dyskeratosis, reaching the trunk and the seborrheic zones, not itchy, appeared one month after the introduction of vemurafenib. The histological analysis was typical of a "Grover-like rash" for the 2 patients. DISCUSSION The appearance of acantholytic dyskeratosis under vemurafenib, a BRAF inhibitor, seems related with a paradoxical activation of the MAP-kinases pathway and with a growth acceleration of lesions in which RAS mutations of keratinocytes. Theses dermatoses seem also to occur with dabrafenib. CONCLUSION The patients treated by BRAF inhibitors (vemurafenib and dabrafenib) can present acantholytic dyskeratosis. The arisen of this mild dermatosis does not question, of course, the continuation of the treatment. These cutaneous manifestations can be managed with emollients.
