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

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

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.

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

Recent Findings: Some histopathological and clinical features, such as papillary dermal edema, perivascular C3 deposition, clinically evident edema, and lesions above the waist, may point out renal or gastrointestinal involvement in Henoch-Schönlein purpura (HSP). HSP associated with familial Mediterranean fever differs from typical isolated HSP by showing no deposits of IgA, much younger age, and location of the lesions on the face or the trunk. Read More

Erythema elevatum diutinum (EED) is a rare form of vasculitis characterized clinically by red-violet brown papules, plaques, and nodules mainly involving the extensor surfaces; histologically by leukocytoclastic vasculitis in early lesions, and fibrosis and cholesterolosis in late lesions. EED has been associated with many systemic disorders including infections, autoimmune disorders, and both benign and malignant hematological disorders. As it is a rare form of vasculitis and only 250 cases reported till date, we report a case of EED in association with IgA monoclonal gammopathy with partial response to dapsone treatment. Read More
