A patient with Netherton's syndrome who was followed since birth had previously been diagnosed as having Leiner's disease and acrodermatitis enteropathica; the disorder was recognized clinically when the patient was 20 years of age. Therapy with 13-cis-retinoic acid significantly aggravated the ichthyosis and induced increased fragility of the skin. This patient also had an intermittent aminoaciduria with clinical investigations that showed normal renal function. Furthermore, the aminoaciduria resolved spontaneously after the discontinuance of topically applied corticosteroids. The normal results of clinical studies and a review of the literature suggest that the aminoaciduria may have been artifactual because excess absorption of topically applied corticosteroids directly affects the renal tubules and impairs renal reabsorption or enhances the free excretion of amino acids. We review forty-two other cases of Netherton's syndrome in the literature and reaffirm the significance of associated ichthyosis, atopy, trichorrhexis invaginata, and other findings in this unique syndrome.
