This chapter aims to draw attention to the features that distinguish drug-induced vasculitis from those of idiopathic autoimmune syndromes, first and foremost primary vasculitides. Development of a systemic drug-induced syndrome only develops in a minority of patients treated with a drug over a prolonged period of time, whereas cutaneous vasculitis occurs quite commonly. The most frequent sympt...

PURPOSE OF REVIEW Vasculitis refers to heterogeneous clinicopathologic disorders that share the histopathology of inflammation of blood vessels. When unrecognized and therefore untreated, vasculitis of the nervous system leads to pervasive injury and disability making this a disorder of paramount importance to all clinicians. RECENT FINDINGS Remarkable progress has been made in the pathogenes...

OBJECTIVES Rheumatoid arthritis is a polygenically controlled systemic autoimmune disease. Rheumatoid vasculitis is an important extra-articular phenotype of rheumatoid arthritis that can result in deep cutaneous ulcers. The objective of this study was to establish a correlation between the frequency of major histocompatibility complex class I/II alleles and killer immunoglobulin-like receptor ...

Vasculitis has been seen in rectal biopsies from 22 patients over a six year period. The most common finding was a necrotising vasculitis of small arteries, indistinguishable from that seen in polyarteritis nodosa (PAN). Sub-acute, chronic ("burnt out") and leucocytoclastic changes were also seen. Sixteen patients had vasculitis complicating rheumatoid arthritis (RA), 3 PAN and 3 overlap syndro...

Vasculitis may be associated with infection, immunization or anti-microbial drugs. Infections are responsible for a number of different types of vasculitis. Conversely, patients with vasculitis may develop infections, which sometimes mimic relapse. The aim of this review is to summarize the various aspects of the inter-relationship between vasculitis and infection, and the physiopathological me...

Although the aetiology of anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis remains unclear, it is generally believed that environmental factors such as infections contribute to its development of ANCA-associated vasculitis. Prior Epstein-Barr virus (EBV) infection is reported to be a trigger of systemic vasculitis. We herein report three cases of ANCA-associated vasculitis pres...

Childhood vasculitis is a challenging and complex group of conditions that are multisystem in nature and often require integrated care from multiple subspecialties including rheumatology, dermatology, cardiology, nephrology, neurology, and gastroenterology. vasculitis is defined as the presence of inflammation in a blood vessel that may occur as a primary process or secondary to an underlying d...

Cutaneous vasculitis has been described in association with various hematological malignancies, but it seems to be very uncommon among non Hodgkin's lymphomas (NHL). For this reason no attention has been given to the peculiarity of this rare association. We identified 5 cases of cutaneous vasculitis among 315 NHL patients examined at our Institution from 1984 through 1990 and after the appearan...
