These neoplasms generally are associated with an indolent course, characteristic endoscopic ultrasonographic (EUS) findings, and a variable histo\u2010 and cytomorphology ranging from hyperplasia to carcinoma. Cytological specimens obtained by endoscopic ultrasound\u2010guided or percutaneous fine\u2010needle aspiration (FNA) are characterized by a background containing abundant mucin in which are entrapped single or loosely cohesive clusters of neoplastic cells characteristically showing a goblet\u2010cell morphology. The degree of nuclear atypia, cell crowding, and cell shape varies between smears within a single case and between cases. Cytomorphological examination, when coupled with EUS features, is accurate for the diagnosis of these lesions but often it underdiagnoses the grade of the neoplasm. Diagn.
