Systemic paraneoplastic vasculitis secondary to papillary carcinoma of the thyroid

Summary Systemic vasculitis secondary to thyroid carcinomas is exceptional. We report the case of a 55-year-old woman who presented with systemic vasculitis involving leucocytoclastic cutaneous vasculitis and renal disorders secondary to papillary thyroid carcinoma (PTC). Her symptoms resolved completely after total thyroidectomy. Other causes of vasculitis were excluded. To our knowledge, this is only the second case reported of systemic vasculitis associated with PTC in a paraneoplastic manner.
