Juxtaglomerular Cell Cause of Secondary Hypertension in an Adolescent

Acta Endo (Buc) 2020, 16 (3): 359-361
doi: 10.4183/aeb.2020.359

Reninoma (juxtaglomerular cell tumor) is a rare cause of renin-mediated hypertension. We reported a 18 year old woman with history of hypertension for 3 years. Laboratory findings showed severe hypokalemia and markedly increased levels of renin and aldosterone. Kidney ultrasonography, abdominal computed tomography and magnetic resonance imaging revealed a small mass in the middle region of the right kidney. The patient underwent nephron-sparing surgery; immunohistochemical results demonstrated typical features of reninoma. Postoperatively, blood pressure and potassium levels were normal at 1 month follow-up.

Keywords: hypertension, renin, reninoma, juxtaglomerular cell tumor, hypokalemia.
