[Grawitz's tumor with arterial hypertension in children. Apropos of a case]

A boy of two years has an hematuria which was first related with an hypertensive acute glomerulonephritis. However because of recurrency of the hematuria radiological investigations were performed and a solid tumor of the right kidney was discovered. The arterial hypertension regressed after the right nephrectomy. Pathology demonstrated a tumor of Grawitz which is rare in children and which is seldom associated with an arterial hypertension. We found only five similar cases in the literature. Arterial hypertension can be related either with a compression of the renal artery of with an inadequate secretion of renin by the tumor.
