Glucagonoma with two pancreatic masses and pulmonary metastases as debut of MEN-1.

This is a rare case of a patient with type 1 multiple endocrine neoplasia (MEN-1) syndrome. The case is further unusual in that the glucagonoma debuted with two synchronic pancreatic masses at the time of diagnosis and with pulmonary metastases as the primary site of metastasis and not the more usual site of the liver.
