Abstract

The juxtaglomerular cell tumor is a rare benign tumor which causes surgically correctable hypertension. We report a case of hypertension caused by juxtaglomerular cell tumor in a 17-year old man. He presented with hypokalemia, metabolic alkalosis and hyperreninemic hyperaldosteronism. Renal angiography showed no evidence of renal artery stenosis. Though no mass was suspected in renal angiography, CT scan showed a well demarcated mass, 3 cm in diameter, in the upper portion of left kidney, which was resected and diagnosed to be a juxtaglomerular cell tumor. After resection of the tumor, blood pressure was normalized with resolution of hypokalemia, metabolic alkalosis and hyperreninemic hyperaldosteronism.
