At the end of the session, the participants will be able to:
This workshop will cover practical issues of cytology in the challenging areas of pancreatic FNA specimens, bile duct brushings and lung/mediastinal FNAs performed by endoscopy (EBUS). Increased use of endoscopic ultrasound-guided fine needle aspiration of lesions at these sites has rendered this a significant area of medical/non-gynecologic cytology, and one in which many pathologists possess limited training. The risks of over- and under-diagnosis are significant; we review the cytologic appearance of benign and reactive changes in comparison with the neoplastic/malignant lesions expected. We will review the following information in a case-based PowerPoint presentation: clinical history, diagnostic imaging findings, fine needle aspiration cytology (Diff Quick and Pap stained), cell blocks/core biopsies, ancillary studies and pertinent literature reviews. The role of rapid on-site cytologic evaluation for triaging samples will also be discussed. The workshop will be of value to: pathology residents, cytotechnologists, general and anatomic pathologists.
