A set of identical female twins developed hematuria and a salt-losing state three days after birth. Evaluation at 10 months of age for failure to thrive revealed severe hypertension associated with interstitial nephritis and massive medial hypertrophy of the renal arterioles. Known causes of hypertension have been eliminated. To our knowledge, this clinical picture has not been previously described.
