cutaneous polyarteritis nodosa

Ari Morimoto, Ko-Ron Chen
BACKGROUND: There is controversy on whether lymphocytic thrombophilic arteritis (LTA) and macular arteritis (MA) are a different entity from cutaneous polyarteritis nodosa (C-PAN). OBJECTIVE: To evaluate the controversy on LTA/MA by examining the morphologic changes during the dynamic inflammatory process. MATERIALS AND METHODS: A clinical and histopathological investigation of 46 biopsy specimens from 21 histopathologically proven C-PAN patients at our hospital was performed...

OBJECTIVES: Polyarteritis nodosa (PAN) is a systemic necrotizing vasculitis of medium-sized visceral vessels. However, cutaneous arteritis (CA) and gastrointestinal (GI) vasculitis are forms of single organ vasculitis having indistinguishable histopathological findings from PAN. The aim of this study was to evaluate and compare the clinical characteristics, treatment, and outcomes of patients with systemic PAN, CA and GI vasculitis. METHODS: Retrospective cohorts were assembled of patients with PAN, CA and GI vasculitis between 1980 and 2014...

We measured both serum anti-phosphatidylserine-prothrombin complex (anti-PSPT) antibodies and anti-moesin antibodies, as well as various cytokines (interleukin [IL]-2, IL-4, IL-5, IL-10, IL-13, IL-17, granulocyte macrophage colony-stimulating factor, γ-interferon, tumor necrosis factor-α) levels in polyarteritis nodosa (PAN) patients with cutaneous manifestations. All patients showed the presence of a histological necrotizing vasculitis in the skin specimen. They were treated with i.v. cyclophosphamide pulse therapy (IV-CY) and prednisolone therapy or steroid pulse therapy...

Cutaneous polyarteritis nodosa (CPAN) is characterized by a necrotizing vasculitis of small and medium-sized arteries in the skin, which can be associated with fever, arthralgia, myalgia, and neuropathy, but, unlike polyarteritis nodosa (PAN), there is no visceral involvement. CPAN is rare in childhood. We report two siblings who developed CPAN during childhood. Interestingly, both had Mediterranean fever gene (MEFV) mutation, i.e. heterozygous E148Q. They also shared HLA-A24, -DR15 alleles. Simultaneous occurrence of MEFV mutation and HLA alleles with CPAN has never been reported in Japan...

A 60-year-old man presented with cutaneous vasculitis, leucopenia and psoriasis. He was treated initially with ciclosporin A. On withdrawal of ciclosporin, due to inadequate improvement of cutaneous vasculitis, he developed psoriatic arthritis. Worsening neutropenia and pancytopenia, believed to be immune mediated, developed. He was treated with prednisolone, methotrexate and adalimumab but developed pneumocystis pneumonia. Leucocyte levels improved markedly with granulocyte colony-stimulating factor (G-CSF)...

BACKGROUND: Neutrophil elastase plays an important role in skin inflammation induced by neutrophil infiltration. Elafin is an inducible elastase inhibitor expressed by keratinocytes, and is known to be involved in pathogenesis of neutrophilic skin disorders such as psoriasis. METHODS: Immunohistochemical studies of elafin expression in the cases of vasculitis were performed. Induction of elafin expression in cultured vascular cells and its effect on neutrophil migration were studied in vitro...

OBJECTIVE: To describe the clinical features, genotype, and treatment in a series of subjects with confirmed adenosine deaminase 2 (ADA2) deficiency. METHODS: All symptomatic subjects were referred for genetic testing for suspected ADA2 deficiency; relatives of index cases were also screened. Demographic, clinical, and laboratory characteristics and treatments were recorded. Genetic analyses included whole-exome sequencing in 4 subjects and Sanger sequencing of CECR1 (the gene for cat eye syndrome chromosome region candidate 1) in all subjects...

INTRODUCTION: The vascular disorders in systemic lupus erythematosus (SLE) result from various mechanisms and presentations (inflammatory disease or vasculitis, atherosclerosis). CASE REPORT: We report on a 34-year-old man with cutaneous, articular, neurological and nephrologic SLE. He presented with catastrophic haemorrhage on microaneurysm rupture of the left hepatic artery. After blood transfusions and immunosuppressive treatments, his condition improves. CONCLUSION: Uncommon complication in SLE patients, digestive vasculitis with microaneurysms may occur as in polyarteritis nodosa...

OBJECTIVES: To determine the incidence and clinical features of paediatric primary vasculitis in patients from one centre in Eastern China. METHODS: Medical records of paediatric patients diagnosed with primary vasculitis between January 1999 and December 2013 were retrospectively reviewed. For Henoch-Schönlein purpura (HSP) and Kawasaki disease (KD), patients included in the analyses had data available for the previous 5 years. RESULTS: In total, 1896 patients were identified, of whom 1100 had HSP, 760 had KD, 23 had Takayasu arteritis, five had polyarteritis nodosa, four had cutaneous polyarteritis, three had Behçet's disease and one had microscopic polyangiitis...

BACKGROUND: Autoimmune manifestations may occur in patients with hairy cell leukemia (HCL), and some rare cases of polyarteritis nodosa and leukocytoclastic vasculitis have been reported. However, data regarding the treatment of these cutaneous manifestations are lacking, given the rarity of the concomitance of HCL and vasculitic syndromes. CASE PRESENTATION: We present a 37-year-old man with paraneoplastic leukocytoclastic vasculitis complicating newly diagnosed HCL...

Polyarteritis nodosa (PAN) is a systemic necrotizing vasculitis predominantly targeting medium-sized arteries. PAN is a rare form of vasculitis, and the precise frequency of this disease is difficult to determine. The major environmental factor associated with PAN is HBV infection. The pathogenesis of "idiopathic PAN" remains enigmatic, although the clinical responses to immunosuppressive therapy support the concept that immunological mechanisms play an active pathogenic role. The spectrum of disease ranges from involving a single organ to polyvisceral failure...

The aim of our study was to analyze clinical features, laboratory findings, treatment, course and outcome of different types of vasculitis in children. All children aged up to 18 years that have been diagnosed with a vasculitis disorder from 2002. to 2012. at the Department of Paediatric, University Hospital Centre Zagreb according to EULAR/PRES/PRINTO criteria were included in the study. Vasculitis was diagnosed in 180 children, 101 girls and 79 boys, mean age 7.19 ± 3.7 years, with an average follow-up of 5...

UNLABELLED: Cutaneous polyarteritis nodosa (CPAN) is a rare disease that affects small and middle caliber vessels of the deep dermis and subcutaneous tissue and its etiopathology remains yet to be understood. METHODS: Retrospective review of twenty two cases diagnosed as CPAN and confirmed by skin biopsy over the last 11 years was evaluated in our department. RESULTS: We found predominance in white woman, mean age of 39.4 years, showing no comorbidities in most of our sample...

BACKGROUND: Cutaneous polyarteritis nodosa (cPAN) is a skin medium vessel neutrophilic arteritis with livedo, nodules, and ulcerations. Macular lymphocytic arteritis (MLA) is a small arteritis with erythematous or pigmented macules and typical histologic features (a lymphocytic infiltrate, concentric fibrin ring, no disruption of the internal elastic lamina). OBJECTIVE: We sought to assess the frequency of clinical and histologic features of MLA in patients with cPAN...

BACKGROUND: Macular lymphocytic arteritis is a recently described type of cutaneous vasculitis involving vessels of medium size. Authors consider it as a form of polyarteritis nodosa. Herein we report a case of macular lymphocytic arteritis during the course of which periarteritis nodosa appeared. PATIENTS AND METHODS: A 50-year-old man, with no history other than chronic venous insufficiency of the lower limbs, presented with an asymptomatic eruption involving all four limbs, mainly the lower limbs, and appearing in episodes...

Polyarteritis nodosa is a rare vasculitis in children characterized by necrotizing inflammation in small and medium size arteries. It is classified into systemic and cutaneous PAN according to the presence of systemic symptoms or visceral involvement. We describe the case of a 14-year-old girl with cutaneous Polyarteritis nodosa with an atypical clinical presentation.
