RESUMO

PURPOSE: We aimed to show the increasing incidence of invasive fungal infections due to Volvariella Volvacea in patients with immunosuppression. METHODS: We present a case of an invasive fungal infection caused by Volvariella volvacea, and summarize the clinical and pathological features based on this case and a review of the literature. RESULTS: A total of seven patients with IFIs due to Volvariella Volvacea have been reported in the literature. The majority of cases have been obtained between 2019 and 2022. Including our case, they all had acquired immunosuppression. The lung and brain were the most commonly affected organs. All eight of these patients received antifungal therapy, but five still died one to seven months after occurrences of IFIs. CONCLUSION: The incidence of invasive fungal infections due to Volvariella Volvacea is increasing in recent years. It mainly occurred in patients with immunosuppression, especially in patients with malignant hematological cancers, and increased mortality.

RESUMO

BACKGROUND: Due to the immune-mediated nature of non-infectious cutaneous vasculitis, skin biopsy specimens are often submitted for direct immunofluorescence (DIF) testing when vasculitis is considered clinically. However, evidence regarding the clinical value of DIF has not been rigorously appraised. OBJECTIVE: In this scoping review, we aimed to systematically evaluate the peer-reviewed literature on the utility of DIF in vasculitis to assist with the development of appropriate use criteria by the American Society of Dermatopathology. METHODS: Two electronic databases were searched for articles on DIF and vasculitis (January 1975-October 2023). Relevant case series involving more than or equal to three patients, published in English, and with full-text availability were included. Additional articles were identified manually via reference review. Due to study heterogeneity, findings were analyzed descriptively. RESULTS: Of 255 articles identified, 61 met the inclusion criteria. Cumulatively representing over 1000 DIF specimens, several studies estimated DIF sensitivity to be 75%. While vascular immunoglobulin A (IgA) deposits on DIF were associated with renal disease, other systemic associations were inconsistent. Vascular IgG deposition may be overrepresented in ANCA-associated vasculitis. Granular vascular and epidermal basement membrane zone Ig deposition differentiated hypocomplementemic from normocomplementemic urticarial vasculitis. Few studies have assessed the added value of DIF over routine microscopy alone in vasculitis. CONCLUSIONS: This scoping review discovered that DIF testing for vasculitis has been performed not only for diagnostic confirmation of vasculitis but also for disease subtype classification and prediction of systemic associations. Future studies on test sensitivity of DIF compared to that of histopathology are needed.

RESUMO

With the global introduction and widespread administration of COVID-19 vaccines, there have been emerging reports of associated vasculitis, including leukocytoclastic cutaneous vasculitis (LCV). In this paper, we present a case of a 68-year-old female patient who developed painful purpuric skin lesions on her feet 12 days after administration of the inactivated COVID-19 vaccine BBIBP Cor-V with histopathological confirmation of LCV and no signs of systemic involvement. The case is followed by a comprehensive literature review of documented LCV cases associated with COVID-19 vaccination with overall 39 articles and 48 cases of LCV found in total. In the majority of cases (56.3%) the first symptom occurred after the first dose of the COVID-19 vaccine, with symptoms manifesting within an average of seven days (6.8 ± 4.8) post-vaccination. The adenoviral vaccine Oxford-AstraZeneca (41.7%) and the mRNA vaccine Pfizer-BioNTech (27.1%) were most frequently associated with LCV occurrences. On average, LCV resolved within 2.5 (± 1.5) weeks. The preferred treatment modality were glucocorticoids, used in 70.8% of cases, resulting in a positive outcome in most cases, including our patient. While the safety of a subsequent dose appears favorable based on our review, individual risk-benefit assessment is crucial. This review emphasis the importance of considering COVID-19 vaccination as a potential trigger for the development of cutaneous vasculitis. Despite rare adverse events, the benefits of the COVID-19 vaccination outweigh the risks, highlighting the importance of immunization programs.

RESUMO

In 2020, Beck et al1 described a novel adult autoinflammatory syndrome entitled VEXAS (Vacuoles, E1 enzyme, X-linked, Autoinflammatory, Somatic), a newly-discovered disorder that connected previously unrelated inflammatory syndromes and a prototype for a new class of hematoinflammatory diseases.2 Eighty-nine percent of published cases have documented skin involvement, but despite the high incidence and diagnostic accessibility of skin manifestations, there has been little focus on the dermatological features of VEXAS syndrome thus far. A PubMed search of all published case reports of VEXAS syndrome to date was performed, with inclusion of all cases confirmed by genetic sequencing, and this review summarizes the reported dermatological signs. There have already been 141 confirmed published cases since original publication, 126 of which had documented cutaneous signs.1-34 A wide range of skin presentations are reported, including Sweet-like urticated and tender erythematous nodules, cartilaginous involvement with chondritis, cutaneous vasculitis, and periorbital angiodema.1-34 Many patients had been diagnosed with Sweet syndrome, relapsing polychondritis, polyarteritis nodosa, or erythema nodosum.1-34 Hallmarks of skin histopathology are a neutrophilic dermatosis with coexisting or exclusive leukocytoclastic vasculitis.1 The new classification therefore helps link previously disparate inflammatory skin conditions into a unifying pathophysiological pathway.

RESUMO

The purpose of the study is to highlight clinical signs that are either suggestive of or against the diagnosis of AHEI to improve diagnosis and management. The medical records of children under 3 years old diagnosed with AHEI were retrospectively reviewed. Clinical data and photographs were reviewed by three independent experts, and the cases were classified as probable, doubtful, or unclear AHEI. Of the 69 cases of children diagnosed with AHEI included in 22 centers, 40 were classified as probable, 22 as doubtful, and 7 as unclear. The median age of patients with probable AHEI was 11 months [IQR 9-15], and they were in overall good condition (n = 33/40, 82.5%). The morphology of the purpura was targetoid in 75% of cases (n = 30/40) and ecchymotic in 70% of cases (n = 28/40) and affected mostly the legs (n = 39/40, 97%), the arms (n = 34/40, 85%), and the face (n = 33/40, 82.5%). Edema was observed in 95% of cases and affected mostly the hands (n = 36/38, 95%) and feet (n = 28/38, 74%). Pruritus was absent in all patients with probable AHEI and described for 6/21 with doubtful AHEI (29%). AHEI was the original diagnosis in only 24 patients (n = 24/40, 60%). The major differential diagnoses were purpura fulminans and urticaria multiforme.  Conclusion: AHEI, which the diagnosis is made on clinical findings, is often misdiagnosed. Purpuric lesions localized on the face/ears, arms/forearms, and thighs/legs with edema of the hands without pruritus in a young child with a good overall condition are highly suggestive of AHEI. What is Known: •Acute hemorrhagic edema of infancy (AHEI) is a cutaneous leukocytoclastic vasculitis affecting children under 3 years old. •Appropriate diagnosis is important to distinguish this benign disease from more serious diseases to avoid investigations and treatments, iatrogenic harm and unnecessary follow-up. What is New: •AHEI is an uncommon disorder often misdiagnosed by pediatricians and dermatologists. •Purpuric lesions localized on the face/ears, arms/forearms, and thighs/legs with edema of the hands without pruritus in an infant with a good overall condition are highly suggestive of AHEI.

RESUMO

BACKGROUND: Leukocytoclastic vasculitis (LCV) is a vasculitic inflammation against blood vessels. Various anticancer therapies can cause vasculitis, but capecitabine-induced LCV is an unusual entity. Here, we describe an LCV case associated with neoadjuvant capecitabine use for locally advanced rectal cancer (LARC). CASE REPORT: A 70-year-old man presented with rectal bleeding. A colonoscopic biopsy revealed rectal adenocarcinoma and he was diagnosed with LARC after imaging studies. Capecitabine plus radiation therapy was started as a neoadjuvant treatment. MANAGEMENT AND OUTCOME: Seven days after the first capecitabine dose, the patient was admitted with a rash. The LCV diagnosis was histopathologically proven. Capecitabine was withheld. After the patient's rash began to regress under corticosteroid pressure, capecitabine was started at a lower dose. His treatment was completed successfully with oral corticosteroids plus low-dose capecitabine. DISCUSSION: We aimed to point out a rare and unusual adverse effect of a frequently used drug in oncologic practice.

RESUMO

Acute generalized exanthematous pustulosis (AGEP) is a rare skin eruption characterized by widespread erythematous lesions covered with numerous pustules. Leukocytoclastic vasculitis is now considered an uncommon but possible histopathological feature within the clinical and pathological spectrum of AGEP. Our report describes a rare case of AGEP overlapping with cutaneous small vessel vasculitis, a condition that has only been reported once in the literature.

RESUMO

Aortitis is a rare complication of the coronavirus disease 2019 (COVID-19) and is often treated empirically with steroids. We present a case of spontaneous resolution of aortitis without treatment. A 65-year-old man was admitted to our intensive care unit for severe COVID-19 pneumonia and underwent rehabilitation in the general ward. On day 12, he developed fever, and on day 13, he developed right cervical pain and increased inflammatory markers. On day 16, a cervical echocardiogram showed vasculitis in the right common carotid artery, and on day 17, computed tomography (CT) of the neck showed thickening of the arterial wall of the right common to the internal carotid arteries. A retrospective assessment of the CT scan on day 12 showed wall thickening from the thoracic aorta to the abdominal aorta, and a diagnosis of aortitis was made. Autoantibody analysis, culture, and magnetic resonance imaging (MRI) of the head and neck showed no abnormalities. During the investigation of the cause of aortitis, the fever and inflammatory reaction spontaneously resolved and the right cervical pain gradually improved. Therefore, the patient was diagnosed with transient COVID-19-related aortitis. To our knowledge, this is the first report describing the spontaneous resolution of COVID-19-related aortitis.

RESUMO

Vaccinations may induce cutaneous adverse events, due to nonspecific inflammation or immuno-mediated reactions. Several types of vasculitis have been observed. We report on a 71-year-old woman who developed cutaneous small-vessel vasculitis after the second dose of Vaxzevria COVID-19 vaccination, showing leukocytoclastic vasculitis on histopathological examination of a skin biopsy. Cutaneous small-vessel vasculitis is a rare condition which can be idiopathic or secondary to underlying infections, connective tissue disorders, malignancy, and medications. The pathogenesis involves immune complex deposition in small blood vessels, leading to activation of the complement system and recruitment of leukocytes. Exacerbation of small-vessel vasculitis has been reported following the administration of various vaccines, particularly influenza vaccine. It is expected that SARS-CoV-2 vaccine results in the activation of B- and T-cells and antibody formation. We hypothesize that leukocytoclastic vasculitis caused by immune complex deposition within cutaneous small vessels could be a rare side effect of Vaxzevria COVID-19 vaccination.

RESUMO

Leukocytoclastic vasculitis has been reported in the setting of COVID-19 infection and post-COVID-19 vaccination. We report a case of IgA vasculitis (IgAV) post-COVID-19 vaccination, with immunoglobulin A (IgA) immune deposits in the skin and renal involvement. SARS-CoV spike protein immunohistochemical staining was negative. IgAV with skin and renal involvement is a potential reaction to COVID-19 vaccination.

RESUMO

Leukocytoclastic vasculitis (LCV) is the vasculitis of small vessels. In this report, we describe a 38-year-old male patient who presented to our outpatient clinic with a 1-week history of rash on his lower extremities that had started 4 days after receiving the Pfizer-BioNTech SARS-CoV-2 vaccine. A diagnosis of LCV was made based on clinical and histopathological findings. The patient was treated with antihistamines and prednisolone, after which improvement was observed in the lesions. With this paper, we aim to raise awareness concerning the possibility of LCV development after COVID-19 vaccination.

RESUMO

BACKGROUND: Immunoglobulin A vasculitis (IgA vasculitis) is one of the most common forms of vasculitis in children. It rarely occurs in adults. It is a systemic vasculitis with IgA deposition and is characterized by the classical tetrad of purpura, arthritis/arthralgia, gastrointestinal and renal involvement. Certain types of infections, and pharmacological agents have been reported to be associated with IgA vasculitis. Here, we describe a case of IgA vasculitis triggered by infective endocarditis in a patient undergoing maintenance hemodialysis. CASE PRESENTATION: A 70-year-old man undergoing hemodialysis was admitted because of skin purpura, abdominal pain, diarrhea, and lower back pain. We suspected him as IgA vasculitis based on the clinical features and skin biopsy findings. Transesophageal echocardiography revealed infective endocarditis, which predisposed him to IgA vasculitis. He was treated with antibiotics and low-dose corticosteroids, which led to resolution of vasculitis. CONCLUSIONS: This is the first case of IgA vasculitis triggered by infective endocarditis in a patient undergoing hemodialysis. Patients undergoing hemodialysis are at a high risk of infection because of immune dysfunction and frequent venipuncture. The incidence of infective endocarditis associated with IgA vasculitis is very low, but it has been repeatedly reported. Therefore, it is necessary to consider infective endocarditis in patients with clinical features that indicate IgA vasculitis.

RESUMO

INTRODUCTION: Leukocytoclastic vasculitis is a histopathological term describing vasculitis in which the inflammatory infiltrate in small vessels consists of neutrophils. Although FLOT is given perioperatively in locally advanced, resectable gastric or gastroesophageal junction adenocarcinoma, it has recently become a popular treatment option for metastatic cancers. In this case report, we present a case of FLOT-induced LCV. CASE REPORT: We present a 52-year-old patient with metastatic gastric adenocarcinoma treated with FLOT. The patient developed necrotizing vasculitis in the lower extremity after 5 cycles of FLOT. MANAGEMENT & OUTCOME: After discontinuation of the FLOT regimen, the necrotizing morbid LCV gradually regressed with steroid therapy. DISCUSSION: To the best of our knowledge, our case is the first case of LCV that developed after FLOT chemotherapy. The clinical appearance of the patient, occurrence after chemotherapy, erythematous rash developing on bilateral lower extremities, and palpable purpuric vasculitis made us suspect. We found a potential relationship between FLOT and vasculitis according to the Naranjo scale (score 4 + ).

RESUMO

WHAT IS KNOWN AND OBJECTIVE: Primary myelofibrosis (PMF) is characterized by myeloid cell proliferation and prominent bone marrow fibrosis. Ruxolitinib, a selective inhibitor of JAK 1 and 2, significantly reduces constitutional symptoms and spleen size compared with placebo, and has significant clinical benefits in patients with myelofibrosis. The most common haematological side effects are thrombocytopenia and anaemia, and the most common non-haematological side effects are grade 1-2 diarrhoea and pyrexia. Leukocytoclastic vasculitis is small vessel vasculitis, characterized histopathologically by immune complex-mediated vasculitis of the dermal capillaries and venules in the lower extremities, which can be seen as palpable purpura. Although the cause is 50% idiopathic, the aetiology of leukocytoclastic vasculitis can be collected under many headings. CASE SUMMARY: The case is here presented of a patient with PMF who developed leukocytoclastic vasculitis after ruxolitinib treatment. Ruxolitinib was discontinued as the lesions were thought to be drug-related and all skin lesions disappeared approximately 2 months after termination of the drug. When the ruxolitinib treatment was restarted at the same dose (2 × 15 mg), the skin lesions recurred. The drug dose was reduced to 1 × 15 mg, and the rashes disappeared. Currently, the patient has no active complaints and is being followed up with ruxolitinib 1 × 15 mg without any complications. WHAT IS NEW AND CONCLUSION: To the best of our knowledge, leukocytoclastic vasculitis due to ruxolitinib is extremely uncommon. This case report can be considered to contribute to the literature of this rare event.

RESUMO

BACKGROUND: Although vaccination against coronavirus severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has been proven generally safe, rare but potentially serious adverse reactions do occur. Leukocytoclastic vasculitis (LCV) is a small-vessel vasculitis that has been associated with other immunizations, but, to our knowledge, has not been previously reported in association with vaccines directed against SARS-CoV-2. CASE REPORT: We report the case of a 22-year-old man with no known past medical history who presented to the Emergency Department with 2 days of migratory arthritis in his ankles and palpable purpura on his bilateral lower extremities, occurring 10 days after receiving the Johnson & Johnson SARS-CoV-2 vaccine. The patient's clinical presentation was suggestive of leukocytoclastic vasculitis, and this diagnosis was confirmed on skin biopsy. Why Should an Emergency Physician Be Aware of This? Recognition of vasculitides is important for timely treatment and prevention of complications. In a patient presenting with palpable purpura after immunization against SARS-CoV-2, LCV should be promptly considered and worked up by the Emergency Physician, though management is most often entirely outpatient and the clinical course is typically mild and self-resolving.

RESUMO

With the present COVID-19 vaccination drive across the world, adverse skin reactions post COVID-19 vaccine is expected. Majority of these reactions seen were transient or local injection site reactions. However, as the larger population is being vaccinated, certain uncommon dermatological presentations including leukocytoclastic vasculitis, pityriasis rosea, and exacerbation of pre-existing autoimmune diseases are now being reported. Among all the COVID-19 vaccines, most of these reactions are seen with messenger ribonucleic acid-based Pfizer/BioNTech (BNT162b2) and Moderna (mRNA-1273) vaccine. We report two cases of leukocytoclastic vasculitis following ChAdOx1 nCoV-19 corona virus vaccine (recombinant) that bring out potential new dermatological manifestations of recombinant corona virus vaccine being administered across the European, South American, and Asian countries. It is important for all health care workers and patients to be aware of the corona virus vaccine associated adverse cutaneous reactions.

RESUMO

The current studies focus on the association between COVID-19 and certain comorbidities. To the best of our knowledge, the association between severe COVID-19 and dermatologic comorbidities has not been reported yet. In this study, we aimed to describe the dermatologic comorbidities of patients with severe COVID-19 and compare it with the control group. Patients who have died at Usak Training and Research Hospital due to COVID-19 and other diseases in the COVID-19 Intensive Care Units and Internal Medicine Intensive Care Units were recruited into the study. Two groups were compared with each other regarding the most common dermatologic comorbidities. A total of 198 patients including 111 patients with COVID-19 and 87 age and sex-matched patients with other diseases were enrolled in the study. The most common dermatologic comorbidities were pruritus (8.1%), eczema (6.3%), skin infections (3.6%), leukocytoclastic vasculitis (1.8%), and urticaria (0.9%) in the COVID-19 group while they were skin infections (9.2%), eczema (3.4%), pruritus (2.3%), and urticaria (1.1%) in the control group. None of patients in the control group had leukocytoclastic vasculitis. There were no significant differences between COVID-19 and control groups in terms of pruritus, eczema, skin infections, and urticaria (P values were .117, .517, .181, .505, and 1.000, respectively). In conclusion, although it is not statistically significant, it appears that pruritus and leukocytoclastic vasculitis are more common in severe COVID-19 patients. These cytokines-related diseases in the immuno-cutaneous systems may give some clues on the COVID-19 severity. Further studies are required to elucidate the relationship between the immuno-cutaneous system and COVID-19 severity.

RESUMO

INTRODUCTION: Cutaneous leukocytoclastic vasculitis is an inflammatory variant of vasculitis with a variety of causes that only affects the skin. Its pathological manifestations include neutrophil infiltration and nuclear fragmentation. Clinically, it is characterised by a pleomorphic rash, including erythema, purpuric skin lesions, reticulocytosis, necrosis and ulceration. Once formed, local ulcerations are very difficult to heal. CASE PRESENTATION: A 46-year-old female was diagnosed with cutaneous leukocytoclastic vasculitis. The patient's legs exhibited ulcers with a black eschar on the surface. The largest wound was 4.5 × 4.0 cm and the deepest wound was 1.7 × 1.8 × 1.0 cm. The ulcers had been present for 6 months and did not exhibit signs of healing. Treatment was commenced with platelet-rich plasma, and the wounds healed within 1 month. CONCLUSION: Topical application of autologous platelet-rich plasma gel exerts beneficial effects in cutaneous leukocytoclastic vasculitis with regard to wound size reduction, and it induces granulation tissue formation. Platelet-rich plasma may represent a safe and cost-effective treatment for managing cutaneous wound healing to reduce the length of the recovery period.

RESUMO

Acute hemorrhagic edema of infancy is a benign rare presentation of leukocytoclastic vasculitis that affects children between 4 and 24 months of age. It usually involves the distal extremities, face, and ears. We report an atypical presentation of AHEI in a 1 year 5 months old boy starting initially over the trunk and back, then spreading to the face and extremities. Mycoplasma pneumonia IgM was found to be positive. The rash resolved spontaneously within two weeks. Herein we present a case of Mycoplasma induced AHEI with an atypical clinical presentation followed by a review of the literature.

RESUMO

Staphylococcus aureus infections are known to cause leukocytoclastic vasculitis (LCV). Herein, we describe a case of an 18-month-old with LCV caused by enterotoxin-producing methicillin-sensitive Staphylococcus aureus (MSSA) emanating from an unrecognized pharyngeal abscess. It is critical to consider the possibility of extracutaneous sources of MSSA infection when investigating an infant with vasculitis. Prompt diagnosis and appropriate treatment are vital in preventing potentially life-threatening complications.
