Background: Erythema elevatum diutinum (EED) is a rare vasculitis with variable clinical presentation which diagnosis can be challenging. Herein we want to describe the clinicopathological spectrum of findings in five cases of EED.

Methods: We retrospectively analyzed five cases in a single institution collected over a period of 27 years. Read More

Erythema elevatum diutinum (EED) is a rare skin disease caused an Arthrus-type immunological reaction to antigen with immune complex deposition in the cutaneous microvasculature, which leads to tissue damage secondary to the effects of complement and leukocytes. It presents as brown or red cutaneous nodules, papules, or plaques, often on the extensor surfaces of the hands, knees, or elbows. Onset usually occurs in the fourth to sixth decades but possibly younger in patients with human immunodeficiency virus. Read More

A 24-year-old man with untreated human immunodeficiency virus (HIV) infection consulted our outreach clinic owing to the development of numerous asymptomatic nodules on his palms and fingers. Histopathologic evaluation revealed leukocytoclastic vasculitis and prominent fibrosis with a neutrophilic infiltrate consistent with erythema elevatum diutinum (EED). We referred the patient for initiation of antiretroviral therapy and started him on dapsone. Read More

Erythema elevatum diutinum (EED) is a rare cutaneous leukocytoclastic vasculitis thought to be related to increased levels of circulating antibodies. It has been shown to be associated with HIV infection, tuberculosis, as well as various autoimmune diseases. A retrospective review of all cases of EED indexed in PubMed between 1990 and 2014 was performed. Read More

Scrub typhus is becoming a clinically important cause of acute undifferentiated febrile illness in Taiwan. The incubation period is between 6 and 21 days after exposure. It is transmitted by chiggers (larva of trombiculid mite) in long grasses and in dirt-floor homes, with infection characterized by a flu-like illness of fever, headache, and myalgia lasting approximately 1 week.

Erythema elevatum diutinum (EED) is a rare, chronic small-vessel vasculitis that presents as firm, red, violaceous, or brown papules and nodules on the extensor surfaces of the limbs. Oral dapsone is considered first-line therapy for EED; in the current case report, a patient presenting with EED began dapsone treatment and symptoms subsided within two weeks. Seven months later, the patient became pregnant and stopped dapsone owing to her concerns with dapsone use during pregnancy, resulting in recurrence of EED symptoms. Read More

Immunoglobulin A (IgA) vasculitis or Henoch-Schönlein purpura (HSP) typically occurs in the pediatric population, although rare cases also occur in adults. Gastrointestinal (GI) involvement is common. The "classic" histologic finding in IgA vasculitis (HSP) is leukocytoclastic vasculitis (LCV); other histologic features in biopsies of IgA vasculitis (HSP) have only been rarely described.

The neutrophilic dermatoses (NDs) comprise a group of heterogeneous disorders characterized by inflammatory skin lesions that histologically show an intense inflammatory infiltrate composed primarily by neutrophils, with no evidence of infection or vasculitis. Although there are distinct clinical differences in the classical lesions of these disorders, many patients have overlapping features. In this review, we describe the clinical aspects of the main NDs, including: Sweet Syndrome, ND of the dorsal hands, pyoderma gangrenosum, erythema elevatum diutinum, subcorneal pustular dermatosis, neutrophilic eccrine hidradenitis, rheumatoid neutrophilic dermatitis, neutrophilic panniculitis, and aseptic abscesses including their association with underlying diseases and the differential diagnoses.

Erythema elevatum diutinum (EED) is a rare dermatosis with evolving histopathological features that vary according to the age of the lesions, with a variable fibrosis and a fascicled proliferation of spindle cells in late phases. The authors present an otherwise healthy 57-year-old woman with multiple indurated nodules on the inner aspect of both feet. Skin biopsy showed storiform interlacing bundles of spindled cells with plump nuclei and some areas with neutrophils and leukocytoclasia. Read More

Background: Leukocytoclastic vasculitis is typically mediated by deposition of immune complexes and is related to many causes, including medication. To the best of our knowledge, leukocytoclastic vasculitis related to cisplatin has not yet been described in the scientific literature.

Case Presentation: We report a rare case of leukocytoclastic vasculitis after the first cycle of high-dose cisplatin chemotherapy in a patient with larynx carcinoma. Read More

Erythema elevatum diutinum is a rare neutrophilic dermatoses with vasculitis, which presents as persistent, symmetrical, purple or brownish papules and nodules, mainly in the extensor surface of the limbs. We describe a case of erythema elevatum diutinum and polyarthritis as initial manifestations of Crohn's disease associated spondyloarthritis. A 51-year-old man, from São Tomé e Príncipe, with previous history of treated tuberculosis and chronic hepatitis B infection, was admitted due to 4 months history of polyarthritis, hyperpigmented papules on the extensor surfaces, occasional episodes of bloody mucous diarrhea and significant weight loss.

Henoch-Schönlein purpura (HSP) is the most common form of childhood vasculitis. Various viral and bacterial infections, drugs, vaccines, food allergy and even insect bites have been considered as triggering factors in pathogenesis of HSP. Epstein-Barr virus (EBV) infection, which is associated with HSP, have been rarely reported. Read More

Erythema elevatum diutinum (EED) is a rare chronic inflammatory dermatosis and a part of the spectrum of cutaneous leukocytoclasticvasculitis. The most common site of involvement is extensor surface of the extremities, with a predilection for the skin overlying joints, particularly hands, feet, elbows and knees, as well as buttocks and Achilles tendons. Here we report a case of EED with atypical presentation involving palms and soles. Read More

Drug-induced leukocytoclastic vasculitis is a small-vessel vasculitis that most commonly manifests with palpable purpuric lesions on gravity-dependent areas. Vasculitis occurs within weeks after initial administration of medication and demonstrates clearance upon withdrawal of medication. Levetiracetam, a pyrrolidone derivative, is used as an adjunctive therapy in patients with refractory focal epilepsy, myoclonic epilepsy, and primary generalized tonic-clonic seizures. Read More

Immunological vascular phenomena can be the initial manifestation of bacterial infection and endocarditis. Here, we report a rare case of leukocytoclastic vasculitis without immune complexes or cryoglobulinemia in a patient with infective endocarditis, congenital heart disease, and a prior mechanical valve replacement. The patient completely recovered following antibiotic therapy, and skin lesions disappeared without immune suppression, which suggested infection-mediated vasculitis. Read More

Background: Cocaine is a risk factor for acute kidney injury and chronic kidney disease with progression to end-stage renal disease. Levamisole is an adulterant that is added to cocaine to enhance its euphoric effects. Levamisole-adulterated cocaine (LAC) is associated with the distinct clinical syndromes of agranulocytosis, leukocytoclastic vasculitis, cocaine-induced midline destructive lesions (CIMDL), and ANCA-associated vasculitis (AAV) with pauci-immune necrotizing glomerulonephritis.

One of the pathogenic causes of cutaneous inflammatory pseudotumors is chronic localized fibrosing leukocytoclastic vasculitis (CLFLCV), a vasculitic reaction pattern seen in granuloma faciale (GF), a localized vasculitis, and erythema elevatum diutinum (EED), a generalized vasculitis. Patients with myelodysplastic syndromes (MDSs) are at risk for a diverse spectrum of cutaneous neutrophilic dermatoses such as EED. Herein, we report a 74-year-old man who presented with a large ulcerative, fungating tumor affecting the right flexor ankle caused by CLFLCV. Read More
