SYSTEMIC VASCULITIS AND POLYARTHRITIS AS THE PRESENTING FEATURE OF RENAL-CELL CARCINOMA

Leukocytoclastic vasculitis (LV) is a pathologic finding in many disor ders, including infection, malignancy, and systemic vasculitides. We d escribe a patient with palpable purpura resulting from LV, inflammator y polyarthritis, mononeuritis, and a positive anti-neutrophil cytoplas mic antibody (ANCA) who was found to have a renal cell carcinoma. Afte r removal of the carcinoma, the symptoms resolved and have remained ab sent for 1 year. To our knowledge, this is the fifth case report of LV as the presenting feature of renal cell carcinoma and the first to in clude systemic vasculitis, an inflammatory polyarthritis, and a positi ve ANCA.
