A Case of Intraductal Papillary Mucinous Tumor of the Pancreas with Scant Mucin Production

Intraductal papillary mucinous tumors of the pancreas (IPMT) commonly produce large amount of mucin. However, rare cases of IPMTs with scant mucin production were reported. Although such tumors seem to produce little or no mucin at all, immunohistochemical staining usually reveals the histologic evidence of mucin production. We report a case of intraductal papillary mucinous tumor of the pancreas with scant mucin production.
