Vasculitis is an inflammation of the blood vessel accompanied by the presence of leukocytes on the vascular wall, followed by structural damage. It often involves the liver and gastrointestinal system, with manifestations of hematemesis and melena. We report a case of hematesis and melena due to leukocytoclastic vasculitis due to the use of antibiotics.

ABSTRACT
A 59-year-old lady with underlying hypothyroidism presented with acute contact dermatitis progressed to cellulitis with superimposed bacterial infection and acute kidney injury. She responded to initial management with antibiotics, but a week later, she had cutaneous and systemic vasculitis. Her skin biopsy consistent with immune-mediated leuko-cytoclastic vasculitis and her blood test was positive for cytoplasmic-anti-neutrophil cytoplasmic antibody (c-ANCA). A diagnosis of ANCA-associated vasculitis was made and she was treated with immunosuppressant with plasmapheresis and hemodialysis support for her kidney failure. Despite aggressive measures, the patient succumbed to her illness. This case report demonstrates that soft tissue infection could trigger the development of ANCA-associated vasculitis whilst a background of hypothyroidism serves as a predisposing factor as both condition were reported separately in a couple of case studies before.

The prompt diagnosis of systemic vasculitis is essential as a missed diagnosis can be disastrous. Imaging is of vital importance in achieving a correct diagnosis and in some cases also plays a role in endovascular treatment. In this book, the imaging features of the many different types of vasculitis are clearly demonstrated by means of numerous high-quality illustrations. All relevant imaging modalities are considered, and key distinctive characteristics are highlighted. In addition, each chapter discusses the etiology, epidemiology, pathogenesis, clinical presentation, biology, and treatment of the vasculitis in question. This book is the result of cooperation between expert teams from a range of countries. The wealth of illustrations and informative clinical case studies will prove invaluable for all who may be confronted with these problematic disorders.

The first observation of cold-induced precipitation of serum proteins dates back to 1933, when Wintrobe and Buell first described an unusual case of multiple myeloma in a woman whose serum reversibly precipitated at cold temperatures. In 1947 Lerner and Watson showed cold-precipitable proteins to be gammaglobulins and called them ‘cryoglobulins’ and the corresponding clinical condition ‘cryoglobulinemia’. Meltzer and Franklin in 1966 provided an accurate description of the typical clinical symptoms associated with cryoglobulinemia, showed that they consisted of two different globulin components and, because of the ignorance on its etiology, called this clinical condition ‘essential mixed cryoglobulinemia’. For almost 20 years progress has been rather slow in this field, but when at the end of the ‘80s it finally became possible to detect the occurrence in the serum of antibodies to the hepatitis C virus (HCV), many groups in Europe and the United States almost simultaneously reported that a high proportion of ‘essential’ cryoglobulinemias are in fact associated with HCV infection. This hallmark has resulted in a new impetus and great enthusiasm in carrying out new researches made possible by the awareness that cryoglobulinemia is to be considered an undisputable extrahepatic manifestation of HCV infection. In addition, the evidence that HCV has tropism for hepatocytes and lymphocytes has stimulated new approaches to the autoimmune phenomena and the potential transformation in non-Hodgkin’s lymphomas which not infrequently can be discovered in these patients. The same applies to the obvious therapeutic implications, once the association between HCV infection and mixed cryoglobulinemia has been firmly established. It was thus felt that times were ripe to produce a state-of-the-art survey of the multi-faceted picture of cryoglobulinemia. This book is indeed unique in the detail of its presentation, its completeness and its fundamental approach to the subject. The most qualified authors have been invited to contribute critical articles reviewing significant developments related to each of the eight sections in which the whole treatment has been divided: from basic mechanisms governing interactions between HCV and the immune system to the immunochemical characterization of cryoglobulins and the frequently concomitant serological abnormalities; from genetic features and the role of certain cytokines and chemokines to the cellular compartments of HCV infection and replication; from the clinical manifestations of cryoglobulinemic patients and their potential susceptibility to develop non-Hodgkin’s lymphoma to conventional treatment of the syndrome and the newer, promising therapeutic advances. The reader will appreciate the immediacy of style, the striking illustrations, and the color plates. In addition, the comprehensive review of a systemic disease such as cryoglobulinemia will interest basic scientists and specialists involved in several disciplines, including internal medicine, hepatology, hematology, oncology, infectious diseases, rheumatology, nephrology and dermatology. General practitioners, graduate and post-graduate students will also find in this book an irreplaceable source of update in this fascinating field.
