Roger W. Fox, M.D. Professor of Medicine/Pediatrics University of South Florida Division of Allergy and Immunology Rare, or uncommon clinical diagnosis Spectrum of presentation: clinical characteristics of cutaneous vasculitis may overlap with urticaria Systemic diseases with cutaneous vasculitis constitute the majority of cases, but there are cases of cutaneous vasculitis without a systemic disorder Constitutional symptoms often accompany the rash when associated with a systemic disorder Laboratory tests and skin biopsy are diagnostic Allergist/Immunologist most commonly are consulted to evaluate urticarial vasculitis Nonpruritic urticarial-like lesions and palpable purpura Individual lesions persist 24-72 h (chronic urticaria lesions persist < 24 h) Vasculitis is a rare cause of chronic urticaria (<5%) Diagnosis: Skin biopsy and laboratory Small vessels(typical of urticarial vasculitis) and/or medium sized vessels (usual signs of medium size vasculitis are: purpura with necrosis, livedo reticularis, subcutaneous nodules, ulcerations, digital ischemia) Inflammatory infiltrate on skin biopsy; mostly neutrophils, but eosinophils can be present Direct immunofluorescence dermopathology assay: IgG, IgM, IgA and C3, fibrin deposition Laboratory investigation: Complement studies, cryoglobulins, anti-neutrophil cytoplasmic antibodies (ANCA), ANA, CBC, ESR, serum protein electrophoresis c-ANCA, anti-proteinase 3 (PR3) associated with Wegener’s; p-ANCA, anti-myeloperoxidase (MPO) associated with Churg-Strauss Cutaneous vasculitis often presents as palpable purpuric lesions that may be generalized or limited to the lower extremities or other dependent areas. Urticarial lesions, ulcers, and hemorrahagic blisters also occur. May involve other organs liver, kidney, brain, and joints. Abbas K et al. Cellular and molecular immunology.6th Edition.

HUVS has profoundly low complement levels Small vessel vasculitis with IgA immune complexes Classic triad of palpable purpura, arthritis, colicky abdominal pain. Monitor for chronic nephritis Usual course 4-6 weeks Drugs may be implicated in cutaneous vasculitis Direct immunofluorescent changes in these lesions suggest immune-complex deposition. Drugs implicated: Allopurinol, thiazides, sulfonamides, other antimicrobials, several NSAIDs, interferons and anti-TNF α; metformin and sulfonylurea antidiabetic drugs. The presence of eosinophils in the perivascular infiltrate of skin biopsy may indicate a higher probability of a drug etiology. http://emedicine.medscape.com/article/1049474-overview “Allergic angiitis and granulomatosis” Almost exclusively in individuals with asthma and allergic rhinitis; systemic vasculitis with eosinophilia, associated with fever, malaise, weight loss. The pulmonary involvement dominates the clinical picture. Asthma is a defining feature and precedes the onset of vasculitis. Skin, heart, peripheral nervous system, GI tract and kidney can be involved.
