@entity45 represent a small proportion of @entity660 , but their incidence has been recently increasing. Most @entity45 are identified incidentally, causing a dilemma for both clinicians and @entity1 . In contrast to @entity420 , neoplastic @entity45 may be cured by resection. In general, @entity45 are classified as neoplastic or non- @entity5 . The predominant types of @entity5 include @entity4929 , mucinous @entity5 , @entity14775 , and solid @entity5 . With the exception of serous type, @entity5 , have malignant potential, and in most cases requires resection. Non- @entity5 include @entity9007 , @entity6112 , benign epithelial cysts, @entity45 , squamous lined cysts ( @entity45 in intrapancreatic accessory spleen), mucinous @entity45 , and @entity2696 . The incidence of nonneoplastic, noninflammatory cysts is about 6.3% of all @entity45 . Despite the use of high-resolution imaging technologies and cytologic tissue acquisition with endosonography, distinguishing nonneoplastic from @entity5 remains difficult with most differentiations made postoperatively. Nonetheless, the definitive distinction between non-neoplastic and @entity5 is crucial as unnecessary surgery could be avoided with proper diagnosis. Therefore, consideration of these rare disease entities should be entertained before deciding on surgery.
