title: Systemic vasculitis revealing a benign tumor: a paraneoplastic syndrome?
abstract: Systemic vasculitis is a rare event in the course of malignant tumors and has not been described in association with benign tumors. We report a case of renal oncocytoma in a patient who presented with digital necrosis, arthralgia, myalgia, and a decline in general health. The symptoms resolved fully after tumor excision, supporting a diagnosis of paraneoplastic syndrome.
