After treatment with isophosphamide (5 g/m 2), acute renal tubular acidosis, nephrogenic diabetes insipidus, phosphaturia, glucosuria, ketonuria and generalized aminoaciduria developed in a patient with breast carcinoma. These findings represent drug induced adult Fanconi syndrome. Nonselective proteinuria reaching the nephrotic range was also observed. The tubular and glomerular abnormalities normalized over several weeks, except for the persistence of a mild tubular acidification defect, vasopressin-fast concentrating defect, and mild proteinuria. Retreatment of the patient with a lower dose of isophosphamide resulted in the reappearance of the major features of the syndrome. The effects of the two courses of therapy on tubular and glomerular function were not additive with a time interval between doses of 6 wk.
