Cutaneous leucocytoclastic vasculitis

Extra-articular manifestations (EAMs) in ankylosing spondylitis (AS) are common and most extra-articular manifestations such as acute iritis and inflammatory bowel disease are positively correlated with disease activity of AS. Vasculitis is an extra-articular manifestation of AS. However cutaneous leukocytoclastic vasculitis (CLV) is uncommon in AS patients. In this article, we report a case of a 66-year-old female patient who has had AS for long time. Although the patient's articular manifestations were stable, the aortic aneurysm and CLV continued to occur sequentially...

Myeloperoxidase (MPO) is a pro-oxidant enzyme mainly found in the azurophilic granules of neutrophils. It not only displays a key role in the intracellular microbial killing process but also contributes to the extracellular clearance of several pathogens. This study aimed to detect MPO in cutaneous leukocytoclastic vasculitis (LCV) using immunohistochemistry. We retrospectively collected 22 confirmed cases of skin LCV diagnosed in our pathology department over 11 years (2012-2023). Immunohistochemistry was performed using anti-myeloperoxidase antibody (Leica clone 59A5) on the LeicaBond MAX automated system, following manufacturer's instructions...

OBJECTIVE: Cutaneous polyarteritis nodosa (CPAN) is a distinct clinical entity represented by a chronic, relapsing, benign course, with rare systemic involvement. Treatment is with CSs, CYC or other conventional synthetic DMARDs (csDMARDs). In this case series, we aimed to share our varied clinical experience of successfully treating patients with CPAN, with tofacitinib in a refractory/relapsing course or as upfront monotherapy without CSs/csDMARDs. METHODS: We report this retrospective case series managed at our rheumatology centre in Bangalore from 2019 to 2022...

Cutaneous leucocytoclastic vasculitis (CLV) is a type of small vessel vasculitis, predominantly presenting with palpable purpuras and sometimes with systemic manifestations. The following report describes the case of a woman, who presented with fever, anorexia and maculopapular lesions over both lower limbs. Skin biopsy revealed CLV. CT scan demonstrated bilateral pulmonary nodules, ileocecal wall thickening and generalised lymphadenopathy. Colonoscopy guided biopsy obtained from ileocecal valve ulcer showed epitheloid cell granuloma with Langhans-type giant cells and caseous necrosis...

Granulocyte colony-stimulating factor (G-CSF) administration is associated with a diverse range of cutaneous sequelae. Serious dermatological side effects of G-CSF include the development of Sweet's syndrome and exacerbations of pre-existing inflammatory disorders such as psoriasis. Here, we describe a report of acute leucocytoclastic vasculitis caused by G-CSF therapy associated with anti-Ro and anti-La antibodies in a patient with multiple myeloma. This case highlights the importance of having a high index of suspicion for acute leucocytoclastic vasculitis in patients with haematological malignancies undergoing G-CSF therapy...

IgA-vasculitis is a systemic small-vessel leucocytoclastic vasculitis and is associated with a high morbidity. The disease can progress to IgA-vasculitis with nephritis (IgAVN) which can result in chronic renal failure. Complement activation is involved in the pathogenesis of IgA-vasculitis. A recent study has shown that cutaneous C3c deposition in IgA-vasculitis is associated with a higher risk to develop IgAVN. In the current study we investigated the different complement pathways that are activated in cutaneous IgA-vasculitis in order to reveal potential targets for intervention...

Infective endocarditis is associated with a variety of clinical signs, but its association with multisystem vasculitis is rarely reported. A high index of suspicion is necessary to differentiate a primary autoimmune vasculitis from an infectious cause as the wrong treatment can lead to significant morbidity and mortality. We present a 71-year-old female patient with negative blood cultures, on antibiotics for recent bacteraemia, who presented with cutaneous and renal leucocytoclastic vasculitis. Workup revealed a vegetation adjacent to her right atrial pacemaker lead consistent with infective endocarditis and her vasculitis completely resolved with appropriate antibiotics...

Checkpoint inhibitor therapy is an established cancer treatment option often complicated by the development of immune-related adverse events. Vasculitis has been reported with a broad spectrum of both cutaneous and systemic manifestations and can be complicated by delayed diagnosis. The authors report 2 histologically proven cases of cutaneous leucocytoclastic vasculitis induced by programmed cell-death 1 inhibitor inhibitor nivolumab. As physicians, including medical oncologists and dermatologists, we need to be aware of this clinical entity and the importance of clinicopathological confirmation in this setting to confirm the diagnosis to help guide the management of these complex patients...

Main skin manifestations of COVID-19 have been recently classified. However, little is known about cutaneous histopathological patterns and the presence of SARS-CoV-2 in these skin lesions. We present a healthy 29-year-old man who developed a leucocytoclastic vasculitis for COVID-19 with positive SARS-CoV-2 PCR in skin biopsy.

Ibrutinib is a Burton tyrosine kinase inhibitor (BTKi) approved for the treatment of several hematologic malignancies. Analyze skin adverse events (SAE). All the patients treated with Ibrutinib featuring cutaneous adverse events were selected. Twenty five patients were retrieved with a median interval between Ibrutinib start and SAE time of onset of 120 days. Most common SAE observed involved hairs and nails. Eczematous reaction and leucocytoclastic vasculitis were also detected. One patient had a long-history Ibrutinib treatment and experienced numerous cutaneous adverse events...

INTRODUCTION: IgA vasculitis is a leucocytoclastic vasculitis of small vessels with immune deposits of IgA. It tends to occur in a post-infectious context, though the pathogenic agent is rarely found. OBSERVATION: We report, for the first time, the case of an 81-year old patient who presented with an acute IgA vasculitis with cutaneous and joint involvement during a Klebsiella pneumoniae respiratory infection. Remission of vasculitis was observed after antibiotic therapy alone...

UNLABELLED: We present a case of an 85-year-old woman diagnosed with uncomplicated pyelonephritis, who was treated with intravenous ceftriaxone. Her chronic medications were phenprocoumon, diltiazem and bisoprolol. During the infectious phase, the patient presented tachycardia - despite high-dose beta-blocker treatment - and developed left acute heart failure, with acute renal failure (pre-renal origin). After introduction of furosemide diuretic therapy, clinical conditions improved and better control of the volemic status and heart rate was achieved...

PURPOSE: Recently, there have been an increased number of reports on levetiracetam (LEV) induced cutaneous adverse drug reactions (CADRs). We aimed to identify and critically evaluate all the descriptive studies on LEV induced-CADRs and to describe the possible clinical manifestations, management, and treatment outcomes of the condition. METHODOLOGY: PubMed and grey literature databases were searched from inception to June 2019 without any restriction. We also performed a bibliographic search for additional studies...

BACKGROUND: Bartonella henselae, a Gram-negative, zoonotic, alpha-proteobacteria has been previously implicated in association with cutaneous vasoproliferative lesions (bacillary angiomatosis), nodular panniculitis and multifocal erythema (erythema multiforme) in dogs. OBJECTIVE: Describe clinical, microbiological and histological lesions in a dog with ear margin vasculitis and B. henselae infection. ANIMALS: A 12-month-old, specific pathogen-free intact female beagle dog maintained in a vector-free laboratory animal resource facility...

BACKGROUND: Although cutaneous and mucosal involvement is a major manifestation in Behçet's disease, ulcerated lesions of the extremities are exceptional and poorly known. CASE REPORT: A 57-year-old male patient was diagnosed 7 years ago with Behçet's disease. This diagnosis was made in the presence of recurrent bipolar aphtous ulcers, pseudofolliculitis lesions and retinal vasculitis. After having been lost to follow up for two years, during which his treatment was discontinued, he presented centimetric necrotic ulcerations of the fingers of the hand and of the right big toe...

BACKGROUND: Influenza vaccinations are commonly administered and effectively prevent influenza. Most vaccine reactions are mild and self-limiting with few reported cases of vasculitis. We present a case of vasculitis post-vaccination unique for its dramatic visual presentation and rapid response to treatment with the aim to emphasise possible causation and timely treatment. CASE PRESENTATION: This is a case of a 60-year-old man with chronic idiopathic pulmonary fibrosis, with fever, arthralgias and rash characterised by extensive erythematous plaques on his limbs and trunk 5 days after influenza vaccination...

BACKGROUND: IgA vasculitis (IgAV) is a small-vessel leucocytoclastic cutaneous vasculitis, often associated with kidney and gastrointestinal (GI) manifestations. Although predictive factors for systemic involvement have been extensively studied in children, there is paucity in the literature regarding adult patients. Neutrophil-to-lymphocyte ratio (NLR) is an inflammatory marker, used to assess systemic inflammation in various diseases. OBJECTIVE: We sought to evaluate whether NLR can be used for predicting renal and GI involvement in adult IgA vasculitis patients...
