Adult Fanconi syndrome progressing to multiple myeloma

Abstract

A case of adult Fanconi syndrome is described in which there was urinary excretion of K light chains. After 13 years the patient developed overt myeloma. She also developed an adenocarcinoma of the colon and an adenocarcinoma of the parathyroid gland. These findings are discussed in relation to the known association between adult Fanconi syndrome, renal damage, and myeloma.
