[A case of malignant paraganglioma within the renal sinus].

A case of malignant paraganglioma within the renal sinus is presented. A 51-year-old woman underwent left transabdominal nephrectomy for renal tumor. Pathologically, the tumor was malignant nonchromaffin paraganglioma. This tumor seemed to originate from parasympathetic paraganglions around the left renal artery. Paraganglioma is rare in the literature. Especially, this may be the first report of such a lesion in the renal sinus.
