The development of immunological abnormalities in various neoplasms is a rather common phenomenon. The prevalence of life-threatening systemic vasculitis in malignancy, however, is much lower. Nonetheless we found an unexpected frequency of several autoimmune manifestations, including systemic vasculitis, in certain myelodysplastic syndromes. We illustrate this finding with the case of a 43-year-old man with signs of polyarteritis nodosa-like systemic vasculitis during progression of chronic myelomonocytic leukaemia. Subsequently, we review the literature on the combination of myelodysplastic syndromes and systemic vasculitis and discuss the prognostic consequences, considerations for treatment and possible pathophysiological mechanisms.

Behçet's disease (BD) is a chronic, relapsing, systemic vasculitis of unknown etiology that affects blood vessels of all sizes, potentially leading to severe complications such as coronary artery aneurysms. This report describes the case of a 33-year-old woman with BD who presented with recurrent chest pain. Imaging revealed a large saccular aneurysm in the left anterior descending artery.

IgA vasculitis is a small vessel vasculitis and while it represents the most common form of vasculitis in pediatric populations, it is rare in adults. This manuscript describes a case of skin limited IgA vasculitis in an 84-yearold Caucasian female. The patient presented for bilateral lower extremity rash that occurred roughly one month following a viral upper respiratory illness.

B cell depletion with rituximab, a chimeric monoclonal antibody that selectively targets B cells by binding CD20, has been used off label in severe and resistant systemic lupus erythematosus (SLE) for over two decades. Several biological mechanisms limit the efficacy of rituximab, including immunological reactions towards the chimeric molecule, increased numbers of residual B cells, including plasmablasts and plasma cells, and a post-treatment surge in B cell-activating factor (BAFF) levels. Consequently, rituximab induces remission in only a proportion of patients, and safety issues limit its use.

Granulomatosis with polyangiitis (GPA) is a small-to-medium vessel vasculitis that can affect the skin, respiratory tract, kidneys and other organs. A rare cutaneous manifestation of GPA is pyoderma gangrenosum (PG)-like ulcerations, which can have debilitating and disfiguring consequences. We report the case of a man in his 40s with refractory PG-like ulcerations secondary to GPA, not responsive to conventional immunosuppression, who was successfully treated with rituximab.

Purpose Of Review: Our purpose was to discuss the advantages and disadvantages of various noninvasive imaging modalities in the evaluation of cardiovascular disease (CVD) in patients with autoimmune rheumatic diseases (ARDs). The detailed knowledge of imaging modalities will facilitate the diagnosis and follow up of CVD in ARDs.
Recent Findings: Autoimmune Rheumatic Diseases (ARDs) are characterized by alterations in immunoregulatory system of the body.
