Unusual association of hyperkalemia and hypertension.

We report an unusual association of hyperkalemia, mild hyperchloremic acidosis, and hypertension in a young woman. Pseudohyperkalemia, Addison's disease, renal insufficiency, classical hyporeninemic hypoaldosteronism, isolated hypoaldosteronism, and iatrogenic causes were excluded. The patient's findings were compatible with a rare syndrome designated as type II pseudohypoaldosteronism, Gordon's syndrome.
