Brief overview of what is being presented/discussed (this will also be shown in the Annual Meeting Program Book):
Despite numerous advances in the field, the diagnosis, classification, grading, and management of cystic and intraductal lesions of the pancreatobiliary tract remain controversial. Additionally, recently described entities such as intraductal tubulopapillary neoplasm (ITPN) and intraductal papillary neoplasm of the bile duct (IPNB) remain diagnostically challenging, and their prognostic implications are poorly understood. The mission of the Pancreatobiliary Pathology Society is to educate surgical and cytopathologists on the importance of the advances in this complex area and will hopefully transform the way we practice pancreatobiliary pathology. The Education Committee, in consultation with Society officers, determined the title, contents, and speakers of this companion meeting.
The chosen topics represent a 360-degree expert evaluation of cystic and intraductal pancreatobiliary lesions in the step-wise manner in which they are often encountered, from the surgeon’s perspective, to their cytomorphologic and molecular characteristics, as well as their histomorphology.
Case #4: Quarter 3, 2019
A female in mid-fifties underwent cholecystectomy due to cholelithiasis. No significant previous medical history was noted.
Grossly, the gallbladder showed mild wall thickening with the serosa mostly covered with ragged and fibrotic adipose tissue and yellowish calculi. No mass lesion was identified.
The microscopic findings are shown below (Figures 1-4).

CASE #3: QUARTER 2, 2019
59 year-old man with a 5.0 cm mass in the head of the pancreas
The patient underwent pancreaticoduodenectomy, which showed a 5.0 cm well circumscribed mass confined in the head of the pancreas. The cut surface of the tumor is tan, soft with mixed areas of necrosis and hemorrhage. The following images (Figure 1-4) are representative micrographs of the tumor.
