Glucagonoma associated with calculous pancreatitis.

A Patient with a glucagonoma associated with calculous pancreatitis is reported. The authors know of only one other such patient. Because the calculous pancreatitis developed both upstream and downstream from the tumor, it cannot be attributed to obstruction of the pancreatic duct by the tumor. Continued critical appraisal is needed to determine whether the association of the glucagonoma and pancreatitis is etiologically related or merely coincidental.
