Concurrent Large-vessel Vasculitis and Small-vessel Vasculitis Accompanied by Basal Cell Carcinoma

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.
