[Stauffer's syndrome. Report of a clinical case]

The clinical case of a 52-year-old man with hypernephroma, abnormal hepatic function tests and no evidence of liver metastasis or abnormal histology is described. Liver function tests returned to normal values after nephrectomy. This case presents the features of the syndrome described by Stauffer in 1961 and can be added to the eighty or so cases reported since then.
