Intraductal papillary mucinous neoplasms (IPMN) have been considered difficult to diagnose by fine-needle aspiration (FNA) cytology. We identified 57 cases diagnosed as IPMN or consistent with IPMN by endoscopic ultrasound (EUS)-guided FNA over a 9-yr period. Histologic follow-up was available for 20 patients (35%). Pancreatic neoplasia was demonstrated in 18 ...

Large oropharyngeal concretions--giant tonsillolith--are not very common. Over the last few years only some 50 cases have been reported in the literature. Many tonsilloliths, especially small concretions, are asymptomatic; large concretions, on the contrary, may produce several symptoms. The case is described of a 56-year-old female complaining of dysphagia, odynophagia, ...
