RÉSUMÉ
Urticarial vasculitis is a rare autoimmune disorder characterized by persistent edematous papules and plaques on the skin that last longer than 24 hours, often accompanied by systemic symptoms such as joint pain and fever. Unlike common urticaria, this condition involves inflammation of small blood vessels, leading to more severe and long-lasting skin lesions with a tendency to leave a bruiselike appearance. Diagnosis is challenging and may require a skin biopsy. Associated with underlying autoimmune diseases, treatment involves managing symptoms with medications such as antihistamines and corticosteroids, addressing the immune system's dysfunction, and treating any concurrent autoimmune conditions.

OBJECTIVE: Single-organ cutaneous small-vessel vasculitis (SoCSVV) is an inflammatory skin-limited vascular disease affecting the dermal and/or hypodermal vessel wall. Pathogenetically, idiopathic forms are described, as well as the induction from different triggers, such as infections, drugs, and vaccines. Following the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) pandemic outbreak, cases of cutaneous vasculitis induced by both COVID-19 and COVID-19 vaccinations have been reported in literature. The aim of this study is to provide the most recent evidence on new etiological factors, clinical features, and management of the SoCSVV. PATIENTS AND METHODS: We included 42 patients (22 women, 20 men) with SoCSVV and no systemic involvement in the study. The mean age of the patients was 57.3 years. Palpable purpura was the most frequent clinical manifestation (38 cases-90.4%). All patients were diagnosed with leukocytoclastic vasculitis by skin biopsy. RESULTS: The etiological factors were as follows: idiopathic in 9 (21%) patients, drug-related in 19 (45%) patients, COVID-19 infection-related in 5 (12%) patients, post-COVID-19 vaccination in 5 (12%) patients, paraneoplastic in 2 (5%) patients, and drug and infection and sepsis in 1 patient each. Among the drug-related cases, 16 (84%) were antibiotic-related, and most of them were beta-lactam antibiotics. Eosinophilia was present in skin biopsy in the cases related to vaccination and drugs, while intense necrosis and vascular damage in the skin were observed in the cases related to COVID-19 infection, unlike the others. A rapid resolution was observed with the cessation of drugs and short-term steroid treatment for the precipitating factors. CONCLUSIONS: SoCSVV is usually associated with drugs, preceding infections, and vaccines. COVID-19 infection and COVID-19 vaccinations have been reported as new etiological factors. SoCSVV indicates that the disease seems to be a mild, self-limiting illness with a good clinical result.

ABSTRACT: Giant cell arteritis (GCA) is a diagnosis that clinicians should not miss because of the accompanying risk of irreversible vision loss. GCA can present without the classic symptoms of headache and temporal artery tenderness, which may lead to a delay in diagnosis. Cutaneous findings, although rare, have been associated with GCA. Accordingly, it is imperative to be aware of the broad clinical and histological presentations of GCA, including the cutaneous findings, because they may prove to be harbingers of impending disease. We present a unique case of GCA where 2 distinct cutaneous morphologies, sarcoidal granuloma annulare-like dermatitis and leukocytoclastic vasculitis with granulomatous features, presented simultaneously before the classic symptoms of headache and unilateral vision loss.

Leukocytoclastic vasculitis (LCV) is an idiopathic small vessel vasculitis. Leukocytoclastic vasculitis can be found in a spectrum of diseases and is noted as a rare extraintestinal manifestation of Crohn disease. This case report examines a 55-year-old man with a previous diagnosis of Crohn disease who was admitted after 5 days with a persistent rash. A biopsy confirmed LCV, and the patient followed up with dermatology for outpatient treatment. This study adds to the sparse medical literature on LCV cases relating to Crohn disease.

Scrub typhus is a disease endemic to the Indian subcontinent caused by the obligate intracellular pleomorphic organism, Orientia tsutsugamushi. Scrub typhus, among other acute febrile illnesses, manifests as prodromal symptoms of fever, malaise, myalgia and anorexia followed by a distinct maculopapular rash, hepatosplenomegaly and lymphadenopathy. We report the case of a patient presenting to tertiary care hospital in southern India in 2021 who developed a rare cutaneous vasculitis secondary to infection with Orientia tsutsugamushi. After performing the Weil-Felix test, a diagnostic titre of >1:640 against OXK was obtained. Furthermore, a skin biopsy was carried out which confirmed the diagnosis of leukocytoclastic vasculitis. The patient was treated with doxycycline and showed drastic improvement in his symptoms.

El consumo de cocaína, junto con algunos de sus adulterantes más frecuentes como el levamisol, puede provocar múltiples procesos cutáneos y mucosos, ya sean de índole isquémico, dermatosis neutrofílicas, lesiones destructivas de la línea media y vasculitis asociadas a ANCA, entre otros. Generalmente no se asocia clínica sistémica llamativa.Todos estos cuadros pueden presentar anticuerpos antinucleares, antifosfolípido y contra distintos antígenos de los neutrófilos, en ocasiones con un patrón característico. El estudio histológico suele mostrar cambios vasculares como vasculitis leucocitoclástica, necrosis de la pared y trombos. En este artículo revisamos las características clínicas, serológicas e histológicas de estas entidades, junto con los mecanismos fisiopatológicos implicados, el diagnóstico diferencial y su tratamiento.

Cocaine and some of its main adulterants, such as levamisole, can cause multiple cutaneous and mucosal manifestations, including ischemic complications, neutrophilic dermatoses, midline destructive lesions, and vasculitis associated with antineutrophil cytoplasmic antibodies (ANCAs). Striking systemic symptoms are generally not seen.In all these conditions, positive test results may be observed for antinuclear antibodies, antiphospholipid antibodies, and various ANCAs, sometimes with characteristic staining patterns. Histology typically shows vascular changes, such as leukocytoclastic vasculitis, necrotizing vasculitis, and thrombi. We review the clinical, serologic, and histologic features of cutaneous and mucosal conditions associated with the use of cocaine and also look at pathophysiologic mechanisms, differential diagnoses, and treatments.

Cutaneous vasculitis may be a cutaneous manifestation of systemic vasculitis, a skin-limited variant of systemic vasculitis, or a type of single-organ vasculitis limited to the skin. Careful evaluation is necessary to distinguish these possibilities, differentiate skin-limited from systemic disease, and identify important underlying conditions, if present. Appropriate management depends on disease type and severity. In the case of cutaneous small vessel vasculitis (CSVV), treatment is primarily based on case reports and expert opinion, using a range of immunomodulatory or immunosuppressive therapies. This manuscript presents a systematic and stepwise approach to the evaluation of patients presenting with cutaneous vasculitis, as well as the management of those diagnosed with CSVV, using best available evidence. Studies relevant to the classification, evaluation, and management of skin vasculitis are ongoing.

Cutaneous vasculitis is a recognized and potentially serious adverse event of immunization with several vaccines, and COVID-19 vaccines are no exception. We present a case of cutaneous leukocytoclastic vasculitis occurring 17 days after inoculation with adenoviral vector vaccine (Ad26.COV2.S) in a previously healthy 30-year-old patient with no history of prior adverse events following vaccination. Transient laboratory abnormalities (mild proteinuria, cryoglobulinemia, and slightly diminished C3 complement level) were also noted, but they resolved with the resolution of skin changes after treatment with topical steroids. Although the frequency of cutaneous vasculitis after COVID-19 vaccines is extremely low, it presents an important challenge for the clinician when faced with an uncertain and delicate decision whether these patients can safely receive booster doses of COVID-19 vaccine. Because vaccination certificates are necessary for day-to-day activities and have a limited validity date, this may be an uncomfortable issue.

COVID-19 has been related to several autoimmune diseases, triggering the appearance of autoantibodies and endothelial dysfunction. Current evidence has drawn attention to vasculitis-like phenomena and leukocytoclastic vasculitis in some COVID-19 patients. Moreover, it has been hypothesized that COVID-19 could induce flares of preexisting autoimmune disorders. Here, we present two patients with previously controlled IgA vasculitis who developed a renal and cutaneous flare of vasculitis after mild COVID-19, one of them with new-onset ANCA vasculitis. These patients were treated with glucocorticoids and immunosuppressants achieving successful response. We also provide a focused literature review and conclude that COVID-19 may be associated with triggering of vasculitis and could induce flares of previous autoimmune diseases.

Cutaneous Vasculitides - Clinical Manifestations, Diagnosis, and Aetiology Abstract. Vasculitides are a heterogeneous group of diseases that are classified differently, for example according to the size of the affected vessel or according to primary and secondary causes. The skin is most frequently affected; it can be involved both as single organ vasculitis and in the context of systemic forms. The combination of skin lesions, their anatomical location and information on the time course provide clues for a differential diagnosis. Purpura, blisters, necrosis, ulcerations and possibly a livedo are characteristic manifestations. Constitutional symptoms such as weight loss, exhaustion, fever, and arthralgias are indicative of a systemic form. It is important to differentiate vasculitides from vasculopathies, which can manifest similarly. The most common form in adults is cutaneous leukocytoclastic angiitis, in children IgA vasculitis (Schönlein-Henoch purpura). Various triggers are possible: infections, drugs, autoimmune diseases, and malignancies, whereby up to 50% remain etiologically unexplained. Skin biopsies and laboratory parameters, if necessary supplemented with imaging, are important steps in the clarification process. Treatment is primarily directed at the elimination of a possible triggering cause. Idiopathic cutaneous leukocytoclastic angiitis usually resolves spontaneously; treatment is symptomatic. In more severe cases, topical corticosteroids or calcineurin antagonists are primarily used. In case of therapeutic resistance, systemic immunosuppressants are recommended.
