Reninoma: A Case Report

Reninoma is a tumor of the renal juxtaglomerular cell apparatus that causes hypertension and hypokalemia via hypersecretion of renin. We describe a case of reninoma. Imaging studies revealed the presence of a lesion in the renal cortex, which, on immunohistochemistry, was identified as a juxtaglomerular cell tumor. Following nephrectomy, the blood pressure and hypokalemia were normalized. World J Nephrol Urol. 2015;4(4):267-269 doi: http://dx.doi.org/10.14740/wjnu243w
