Concurrent Large-vessel Vasculitis and Small-vessel Vasculitis Accompanied by Basal Cell Carcinoma: A Case Report.

Variable vessel vasculitis is a rare presentation of systemic vasculitis. We herein report a Japanese woman with large- and small-vessel vasculitis accompanied by basal cell carcinoma. The clinical course of our patient suggested paraneoplastic variable vessel vasculitis. Our case suggests that there are two aspects that need to be considered. First, clinicians should consider cancer-related complications when treating variable-vessel vasculitis. Second, the evaluation of variable vessels is needed when treating paraneoplastic vasculitis.
