[The glucagonoma syndrome. Review of the literature. Apropos of a case].

A patient with typical clinical and biochemical features of a glucagonoma also presented obvious signs of hypokalemia, indicating combined secretion of renin by the tumor. The latter was voluminous, was located in the tail of the pancreas and was of a malignant nature as shown by the development of secondary hepatic metastases. Syndromes associated with glucagonoma and mixed or combined insular tumors are reviewed in detail.
