Fanconi's syndrome in an adult. A case history.

A case of the Fanconi syndrome in an adult presenting with life-threatening hypokalaemia is described. Amino-aciduria, glycosuria, high phosphate and uric acid clearances with reduced plasma levels of these two substances, reduced urinary concentrating power and abnormal urinary potassium loss with a systemic acidosis, were the essential biochemical abnormalities. Osteomalacia was shown by a radiological bone survey.
