Abstract

In this chapter, some of the unique aspects of EUS FNA are first introduced, such as possible confounders in the evaluation of adequacy. Thereafter, the chapter is divided into two main sections: EUS FNA of the gastrointestinal tract and pancreas.

In the gastrointestinal tract, most of the lesions are mesenchymal, and a discussion on basic imaging findings and discriminatory cytologic and IHC features is provided.

In the pancreas, the importance of the triple approach is emphasised, and a sequential approach is provided to working up pancreatic lesions. In particular, the challenging area of cystic lesions is used as an example of how a multifaceted clinical, radiologic and cytologic approach can help to tackle some of the more difficult diagnostic dilemmas.
