title: ANCA-associated vasculitis as paraneoplastic syndrome with colon cancer: a case report.
abstract: Coexistence of a vasculitis and a neoplastic disease is rare and the pathogenesis is unknown. Most of these associations refer to leukocytoclastic or poliarteritis nodosa (PAN)-type vasculitis and hematological malignancies. There are few reports of vasculitis in patients with solid tumours and there are also few reports of paraneoplastic ANCA-associated vasculitis. We report a case of p-ANCA-positive vasculitis with peripheral nerve involvement associated with a colon cancer. Vasculitis resolved after corticoid treatment and surgical removal of the tumour.
