title: Cutaneous leukocytoclastic vasculitis and renal cancer: two cases.
abstract: We report two cases of cutaneous leukocytoclastic vasculitis (CLV) leading to the discovery of an as yet asymptomatic, surgically curable clear cell carcinoma of the kidney. CLV causative factors or associated diseases are usually drugs, infection, or collagen vascular disease, but rarely malignancies. In such cases, these are more often malignant hematologic diseases than solid neoplasms. We believe that in apparently idiopathic CLV, a screening examination should be done to detect any underlying early-stage curable solid malignancy.
