title: Juxtaglomerular cell tumor.
abstract: A 15-year-old female with primary reninism presented with benign hypertension, normokalemia, normal aortagram and normal intravenous pyelogram. The diagnosis was suggested only by a remarkably elevated plasma renin activity (PRA). Selective catheterization of renal vein branches was necessary to make the diagnosis of a tumor. A local resection of the tumor resulted in normalization of blood pressure and PRA. Prior to the definitive surgery, oral propranolol was effective in lowering PRA and blood pressure.
