title: Cutaneous necrotizing vasculitis. Relation to systemic disease.
abstract: Cutaneous necrotizing vasculitis (CNV) is a complex multisystem disease generally involving the skin and mucous membranes, often accompanied by renal, gastrointestinal, pericardial, neurological, and articular signs and symptoms. CNV may be idiopatical or occur in association with a drug, infection, or underlying disease. CNV has been shown in patients with chronic infections (viral, bacterial, protozoa, helminthic), serum sickness, a variety of collagen vascular diseases (systemic lupus erythematous, Sjögren's syndrome, rheumatoid arthritis, Behçet's disease) hyperglobulinemic states, cryoglobulinemia, bowel bypass syndrome, ulcerative colitis, cystic fibrosis, primary biliary cirrhosis and HIV infection. Association with malignancies is not frequent. Lymphoproliferative disorders (Hodgkin's disease, mycosis fungoides, lymphosarcoma, adult T-cell leukemia, multiple mieloma) and solid tumors (lung cancer, colon carcinoma, renal, prostate, head and neck cancer and breast cancer) may be associated with CNV. Whenever possible, treatment is directed at the elimination of the cause. In other cases after adequate laboratory screening local and systemic therapy are recommended.
