Review
BACKGROUND/OBJECTIVES
This study seeks to better define the clinical presentation and histopathology of cutaneous manifestations in childhood eosinophilic granulomatosis with polyangiitis (cEGPA).
METHODS
Case reports were collected from Ovid Medline Database and PubMed using keyword identifiers from 1946 to 2017. Adult patients ≥ 18 years and cases not diagnosed with EGPA by the author were excluded. Sixty-five case reports of cEGPA were initially identified. These were reviewed individually, and fifty cases were determined to meet the American College of Rheumatology criteria for EGPA. No case series examining the cutaneous morphology and histopathology were identified. Cutaneous morphology, lesion location, and cutaneous histopathology results were recorded. Results were analyzed using summary statistics.
RESULTS
Sixty-four percent (32/50) of cEGPA patients presented with cutaneous manifestations. Twenty-nine cases provided specific morphological descriptions and lesion location. Common manifestations included purpura (15/29), subcutaneous nodules (8/29), and a macular/papular/maculopapular rash (8/29). However, twelve different cutaneous morphologies were identified in this review. Lesions occurred most commonly on the extremities (26/29). Twenty-two cases reported corresponding cutaneous histopathology, which revealed extravascular eosinophils (15/22), vasculitis (13/22), and granulomas (5/22). Only one biopsy sample (1/22) had all three classical EGPA characteristics of granulomas, extravascular eosinophils, and vasculitis.
CONCLUSION
With nearly two-thirds of cEGPA patients presenting with cutaneous manifestation, this study highlights the importance of clinical recognition of this disease by dermatologists. While the varied morphology of skin lesions and rarity of this disease makes cEGPA a difficult diagnosis, prompt recognition and treatment will improve outcomes in this patient population.

Review
Cyclin-dependent kinase (CDK) 4/6 inhibitors (palbociclib, ribociclib and abemaciclib) have revolutionized the treatment of metastatic breast carcinoma. They currently form the first-line treatment, in combination with endocrine agents, for the management of locally advanced or metastatic hormone receptor-positive (HR + ), human epidermal growth factor receptor 2-negative (HER2-) breast cancer, the largest subtype of breast carcinoma. CDK 4/6 inhibitors have shown comparable efficacy outcomes with predictable and manageable adverse events. In this setting, dermatologic toxicity appears to be relatively frequent, accounting for up to 15% of all reported adverse events. It is usually mild to moderate in intensity and does not normally constitute a dose-limiting toxicity. The range of dermatologic adverse events includes both non-specific entities (maculopapular rash, pruritus, alopecia) and more characteristic toxicities related to CDK4/6 inhibitors, such as vitiligo-like lesions or cutaneous lupus erythematosus. Finally, more severe or life-threatening skin reactions can occasionally occur. The main dermatologic manifestations associated with CDK4/6 inhibitors, as well as management thereof, are described in this comprehensive review.

Review
The pandemic condition coronavirus disease (COVID-19), caused by the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), can take asymptomatic, mild, moderate, and severe courses. COVID-19 affects primarily the respiratory airways leading to dry cough, fever, myalgia, headache, fatigue, and diarrhea and can end up in interstitial pneumonia and severe respiratory failure. Reports about the manifestation of various skin lesions and lesions of the vascular system in some subgroups of SARS-CoV-2-positive patients as such features outside the respiratory sphere, are rapidly emerging. Vesicular, urticarial, and maculopapular eruptions and livedo, necrosis, and other vasculitis forms have been reported most frequently in association with SARS-CoV-2 infection. In order to update information gained, we provide a systematic overview of the skin lesions described in COVID-19 patients, discuss potential causative factors, and describe differential diagnostic evaluations. Moreover, we summarize current knowledge about immunologic, clinical, and histologic features of virus- and drug-induced lesions of the skin and changes to the vascular system in order to transfer this knowledge to potential mechanisms induced by SARS-CoV-2.

Review
BACKGROUND
The coronavirus disease 2019 (COVID-19) pandemic has affected 18 million people and killed over 690,000 patients. Although this virus primarily causes respiratory symptoms, an increasing number of cutaneous manifestations associated with this disease have been reported.
OBJECTIVE
The aim of this review was to collate and categorize the dermatologic findings reported in patients with COVID-19 and identify specific lesions that may facilitate diagnosis and prognostication.
METHODS
An evidence-based review of the PubMed database was conducted on 14 May, 2020 using the search terms "Covid-19 skin," "Covid-19 rash," "Covid-19 exanthem," and "Covid-19 chilblains." Peer-reviewed publications containing original COVID-19 patient cases and a discussion of the associated cutaneous findings were included in the analysis.
RESULTS
The literature search identified 115 records, of which 34 publications describing 996 patients with dermatologic conditions were included. Case reports (n = 15), case series (n = 13), and observational prospective studies (n = 4) were the most common publication types. Acral lesions resembling pseudo-chilblains were the most frequent lesion identified (40.4% of cases), appearing in young adults (mean age, 23.2 years) after the onset of extracutaneous COVID-19 symptoms (55/100 patients). Erythematous maculopapular rashes affected 21.3% of patients, most frequently impacting middle-aged adults (mean age, 53.2 years) and occurring at the same time as non-cutaneous symptoms (110/187 patients). Vesicular rashes affected 13.0% of patients, appearing in middle-aged adults (mean age, 48.3 years) after the onset of other symptoms (52/84 patients). Urticarial rashes affected 10.9% of patients, appearing in adults (mean age, 38.3 years) and occurring at the same time as non-cutaneous symptoms (46/78 patients). Vascular rashes resembling livedo or purpura were uncommon (4% of cases), appearing in elderly patients (mean age, 77.5 years) and occurring at the same time as non-cutaneous COVID-19 symptoms (18/29 patients). Erythema multiforme-like eruptions, although infrequent (3.7% of cases), affected mostly children (mean age, 12.2 years).
CONCLUSIONS
Vesicular rashes may suggest an initial diagnosis of COVID-19, acral lesions may be most appropriate for epidemiological uses, and vascular rashes may be a useful prognostic marker for severe disease. As a potential correlate to disease severity, prognosis, or infectibility, it is critical that all healthcare professionals be well versed in these increasingly common cutaneous manifestations of COVID-19.

Review
Multisystem inflammatory syndrome in children (MIS-C) affects a small percentage of pediatric patients infected with COVID-19 and is characterized by fever, laboratory evidence of inflammation, multisystem involvement, and severe illness necessitating hospitalization. Skin findings are often present in these patients, and when initially compared with Kawasaki disease, they likely represent distinct phenomena and overall remain poorly characterized. In this retrospective review of 34 case reports and series, we identified cutaneous manifestations documented in 417 of 736 patients (57%) with MIS-C associated with COVID-19. "Rash" was the sole descriptor of skin findings in nearly half of patients. Case reports and smaller case series provided more detail, outlining a broad range of lesion morphologies (polymorphic, maculopapular, morbilliform, erythrodermic, urticarial, reticular, petechial, purpuric) in variable anatomic distribution. More thorough descriptions of dermatologic manifestations in patients with MIS-C are warranted to better characterize this syndrome, as they may lend important insight into pathogenic mechanisms of disease.

Review
Bowel-associated arthritis-dermatosis syndrome (BADAS) is a rare neutrophilic dermatosis that was first described in 1971 in patients who underwent bypass surgery for obesity. Over the years, the number of reported cases associated with medical gastroenterological conditions, particularly inflammatory bowel disease (IBD), has progressively increased. To date, there are no systematic reviews in the literature on BADAS. The design of an a priori protocol was based on PRISMA guidelines, and a search of PubMed and Scopus databases was conducted for articles published between 1971 and 2023 related to the topic. Fifty-one articles including 113 patients with BADAS were analyzed in this systematic review. Bariatric surgery and IBD were the most frequently reported causes of BADAS, accounting for 63.7% and 24.7% of all cases, respectively. A total of 85% of cases displayed the typical dermatological presentation, including urticarial maculopapular lesions centered by a vesicopustule, with the majority of lesions located on the upper limbs (73.5%). Polyarthralgia or localized arthritis were always present. Atypical presentations included cellulitis-like, erythema-nodosum-like, Sweet-syndrome-like and pyoderma-gangrenosum-like manifestations. Gastrointestinal symptoms were frequently observed in IBD-related cases (67.9%). The histopathology showed a neutrophilic infiltrate (96.6%). The most commonly used treatment regimens consisted of systemic corticosteroids, metronidazole and tetracyclines, either alone or in combination. A relapsing-remitting course was observed in 52.1% of patients. In conclusion, BADAS is a neutrophilic dermatosis that presents with a wide variety of cutaneous manifestations, both typical and atypical. Gastrointestinal symptoms are frequently observed, particularly in cases related to IBD. The histopathology is clear but not specific compared with other neutrophilic dermatoses. The diagnosis can be challenging, but the relapsing-remitting course and the strong association with polyarthralgia and gastrointestinal disease can aid in the diagnosis.

Review
Monkeypox virus (MPV) is an orthopox virus in the Poxviridae family that is currently of international concern. It is endemic to Central and Western Africa with two known viral clades. Various African rodents and primates are likely the natural reservoirs. Zoonotic transmission occurs by direct contact with infected animals (e.g., bites, scratches, slaughtering). Human to human transmission occurs through close contact with infected persons (e.g., respiratory droplets, skin-on-skin, or sexual contact) or fomites. Classically, human MPV disease first has a febrile prodrome with lymphadenopathy followed by a diffuse maculopapular to vesiculopustular skin/mucosal lesion eruption. In the current 2022 outbreak, which is primarily affecting men who have sex with men (MSM) currently, the febrile prodrome may be absent and skin/mucosal lesions may be isolated to the genital and anal regions. Rarely, MPV likely has the potential to be neuroinvasive based on animal models, previous case series, and preliminary reports currently under investigation. Even though neurologic manifestations of human MPV infection are rare, given the sheer numbers of increasing cases throughout the world, neurologists should be prepared to recognize, diagnose, and treat potential neuroinvasive disease or other neurologic symptoms.

Review
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causing coronavirus disease 2019 (COVID-19) has been a rising concern since its declaration as a pandemic by the World Health Organization on 11 March 2020. Recently, its association with multiple underlying organs has been identified that includes cardiac, renal, gastrointestinal, nervous systems, and cutaneous manifestations. Cutaneous COVID-19 findings have been supposedly classified into the following categories: vesicular (varicella-like), papulo-vesiculsar, chilblains-like ("COVID toes") maculopapular, and urticarial morphologies. In this review, we aim to focus on the proposed pathophysiology behind the various dermatological manifestations associated with COVID-19 and their associated management. We also included prevalence and clinical features of the different COVID-19-related skin lesions in our review. A comprehensive narrative review of the literature was performed in PubMed databases. Data from case reports, observational studies, case series, and reviews till June 2022 were all screened and included in the review.

Review
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.

A male in his 60s developed a pruritic, maculopapular rash on his torso and arms, sparing his palms and soles. He tested positive for ANA and an initial skin biopsy identified "bullous lupus," supporting the diagnosis of a connective tissue disease. Additional symptoms included headaches, facial nerve palsy and hearing loss, which partially responded to oral corticosteroids. He subsequently developed a steroid-dependent left eye scotoma, neuroretinitis and optic nerve papillitis. Mycophenolate mofetil was added but an attempted oral steroid taper led to a worsening rash, progressive retinitis and papillitis. Neurosyphilis was confirmed by serum positive rapid plasma reagin test, reactive treponema pallidum antibodies, positive cerebrospinal fluid venereal disease research laboratory and positive spirochete immunostain of skin biopsy of lesional (rash) tissue. Treatment with intravenous ceftriaxone resolved his rash and visual symptoms. It is important to consider syphilis as a mimicker of connective tissue diseases.
