Cystic Lesions: Classification and Sampling
Cystic lesions of the pancreas are now being diagnosed much more frequently due to the increased use of modern imaging techniques. The majority are asymptomatic and diagnosed incidentally during investigation for other conditions. Most pancreatic cystic lesions are noninvasive and amenable to resection. However, establishing the true nature of a pancreatic cyst on imaging can be difficult. Similarly, establishing the diagnosis on microscopy can be problematic. The epithelium of neoplastic cysts can become denuded and, with inadequate sampling, lead to a misdiagnosis of a pseudocyst. This chapter discusses the various classifications of pancreatic cysts and includes quick-reference tables for all the neoplastic and nonneoplastic cystic lesions. Guidance is also provided on sampling pancreatic cysts.
