[Grawitz's tumor and provoked hyperlipemia (author's transl)].

After reporting a case of a patient aged 69 years with an inoperable hypernephroma, in whom the presence of a polycythemia and a reduction in the provoked hyperlipemia curve was found to co-exist, the authors review the data in the published literature on the influence on the small intestine of cancers other than those in the gastro-intestinal system. Basing their comments on studies of hypernephromas, they stress that a reduction or delay in the hyperlipemia curve was found in 23 out of 28 patients. This abnormality can only be explained by hypotheses at the present time.
