%0 Journal Article %T Nephrogenic Diabetes Insipidus: A Rare Presentation in Multiple Myeloma %A Mehdi Dehghani %A Vahid Mohammad Karimi %J Middle East Journal of Cancer %D 2012 %I Shiraz University of Medical Sciences %X We report a case of multiple myeloma that presented with anorexia, fatigue, high erythrocyte sedimentation rate, bone marrow plasmacytosis of more than 30%, polyuria,and low urine specific gravity. This unusual presentation was diagnosed as nephrogenic diabetes insipidus secondary to a proximal tubular dysfunction. The tubular functional disturbance appeared to be related to thepresence of lambda-type light chains. The patient was treated withdesmopressine without response. After one month of treatment with thalidomide and dexamethasone for myeloma there was a dramatic response with decreased urine output. %K Nephrogenic diabetes insipidus %K Multiple myeloma %K Lambda light chain %K Amyloidosis %U http://mejc.sums.ac.ir/index.php/mejc/article/view/88/211
