Serous cystic tumors of the pancreas are unique among pancreatic cystic neo
plasms in that they are almost always cytologically monomorphous and biolog
ically benign. The diagnostic challenge for the surgical pathologist is to
recognize the spectrum of architectural variation that may read to misdiagn
osis, either preoperatively or postoperatively, and the additional lesions
and conditions with which serous tumors may be associated. Copyright (C) 20
