1. Is macular lymphocytic arteritis limited to the skin? Long-term follow-up of seven patients,
Abstract Background: Macular lymphocytic arteritis most commonly presents as hyperpigmented macules on the lower limbs. The pathogenesis of this disease is still unclear and there is an ongoing debate regarding whether it represents a new form of cutaneous vasculitis or an indolent form of cutaneous polyarteritis nodosa. Objective: To describe clinical, hi

2. Cutaneous polyarteritis nodosa causing refractory skin deformation and pigmentation as sequel
Abstract: A 39-year-old woman presented with prominent and painful livedo reticularis lesions spreading on her upper and lower extremities. Histopathologically, the small-to medium-sized arteries in the deep dermis and subcutis showed necrotizing vasculitis with cellular infiltration, suggesting cutaneous polyarteritis nodosa. The serum levels of inflammator

3. Cutaneous polyarteritis nodosa
AbstractPolyarteritis 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 clin

4. Alleles HLA-DR in patients with polyarteritis nodosa and microscopic polyangiitis / Alelos HLA-DR em pacientes com poliarterite nodosa e poliangite microscopica
The aim of this study was to evaluate the frequency and clinical associations of HLA-DR alleles in Brazilian Caucasian patients with polyarteritis nodosa (PAN) or microscopic polyangiitis (MPA). We evaluated 29 Caucasian patients with vasculitis classified as PAN or MPA according to the American College of Rheumatology (ACR) 1990 Criteria and Chapel Hill Con

5. Raynaud's phenomenon as initial manifestation of cutaneous polyarteritis nodosa.
The case of a 45 year old man with cutaneous polyarteritis nodosa and Raynaud's phenomenon as initial manifestation of the disease is reported. Although peripheral vascular disease is a well characterised extracutaneous manifestation of cutaneous polyarteritis nodosa, to our knowledge this is the first reported case in which Raynaud's phenomenon was the init

6. POLYARTERITIS NODOSA AND CONGENITAL PYLORIC HYPERTROPHY IN A 3-MONTH-OLD INFANT
A case of polyarteritis nodosa in the first year of life with the clinical picture dominated by pyrexia, an initial upper respiratory element, episodes of tachycardia, and sudden death three weeks after the onset is described. The necropsy showed evidence of polyarteritis nodosa, myocarditis, and valvulitis as well as congenital pyloric hypertrophy. Clinical

7. Polyarteritis nodosa associated with acute cytomegalovirus infection.
A case of polyarteritis nodosa is described in which the onset of the disease was associated with acute infection by cytomegalovirus. Peripheral neuropathy was the predominant clinical feature, and death occurred 4 years after the onset. This is the first recorded case of polyarteritis in which cytomegalovirus is of possible aetiological significance.

8. Coexisting HLA-B27 positive spondyloarthritis and polyarteritis nodosa.
A 38 year old woman presented with widespread polyarteritis nodosa a few years after the onset of HLA-B27 positive spondyloarthritis. The concomitant coexistence of these two disorders suggests a possible association in this genetically susceptible subject.

9. Renal vein thrombosis in cases of polyarteritis nodosa and of the Henoch-Schoenlein syndrome
The occurrence of renal vein thrombosis in a case each of polyarteritis nodosa and the Henoch-Schoenlein syndrome is reported. It is suggested that obliteration of the arterioles that supply the walls of the veins may have initiated the venous thrombosis in these two cases.

10. Acute confusional state and hyponatraemia due to inappropriate antidiuretic hormone secretion in polyarteritis nodosa.
An acute confusional state, which developed in a patient with polyarteritis nodosa (PAN), proved to be secondary to inappropriate secretion of antidiuretic hormone and consequent hyponatraemia. This is a very unusual complication of PAN and may well reflect a direct stimulation of the supraoptic nuclei owing to cerebral vasculitis.

11. Asymptomatic arteritis of the uterine cervix
A necrotizing arteritis in the uterine cervix is described as an incidental finding in surgical material from 10 patients. The histological features are compared with those seen in polyarteritis nodosa. Subintimal hyaline deposition and a relative paucity of neutrophil and eosinophil polymorphs characterized the lesion but the histological appearance was nev
