Steroid profile in a case of adrenal carcinoma with severe hypertension.

The case of a young boy who had Cushing's syndrome and severe hypertension in association with metastatic adrenal carcinoma is described. Marked elevation of the mineralocorticoid 11-deoxycorticosterone was demonstrated in the plasma. 11-Deoxycortisol, 17alpha-hydroxyprogesterone, and urinary tetrahydro-11-deoxycortisol and pregnanetriol were also elevated. Aldosterone excretion was low. The data implicate defective 11beta hydroxylation and suggest that excessive 11-deoxycorticosterone production may have been responsible for the hypertension.
