Wait, Wait, Don’t Tell Me:  Challenging Cytopathology Cases from a Comprehensive Cancer Center
Sue Ellen Martin, M.D. Ph.D.

Educational Objective:
During the course of this tutorial, the participants will:

  1. Gain an understanding of the variety of cytopathology cases seen at a tertiary care center
  2. Review the critical role of FNA in the primary diagnosis of cancer as well as in the staging of disease and the diagnosis of recurrence of disease
  3. Evaluate the efficacy of ancillary techniques such as immunocytochemistry in determining whether a malignant neoplasm is primary or metastatic
  4. Gain an appreciation of the critical role of the cytotechnologist in this practice setting

In this microscopy tutorial, the critical role of the cytopathology service in a university based comprehensive cancer center will be presented through microscopic case studies.
Emphasis will be placed on the clinical utilization of the FNA service including the expectations of clinicians, the number and types of FNAs performed and who performs them, and the value of ancillary studies in rendering an accurate and specific diagnosis.  The importance of the cytotechnologist in this clinical setting will be considered.

 

Tutorial #2 (8:00 am to 9:30 am)

Lymphomania
Ann T. Moriarty, M.D.

Educational Objective:

  1. Learn the limitations and advantages of morphologic evaluation of selected non-Hodgkin and Hodgkin Lymphomas.
