Monoclonal gammopathy associated with idiopathic stenosing papillitis. A case report.

: Stenosing papillitis is a recently recognized cause of obstructive jaundice. Although many liver disorders are associated with a polyclonal increase in serum immunoglobulin levels, a monoclonal increase is relatively rare. A patient with monoclonal gammopathy associated with idiopathic stenosing papillitis is reported. The gammopathy has persisted for 3 years after surgical relief of the obstructive jaundice.
