Intra-operative frozen section interpretations can be challenging, particularly in an era of increasing subspecialization within the field of surgical pathology. Cytologic and pre-operative biopsy assessments have largely eliminated the need for intraoperative tumor classification. Thus, most intraoperative frozen sections are now used for tumor staging to determine resectability, margin assessment, and classification of small lesions discovered during the procedure. In these situations, pathologists are expected to render definitive, rapid diagnoses, often without support of colleagues and ancillary techniques. This course will provide registrants with a practical approach to intraoperative consultatations, illuminate distinguishing features of carcinoma and benign mimics commonly encountered in frozen sections, and improve communication between pathologists and surgeons in the frozen section laboratory.

Target audience:
Our course will be organized to benefit practicing general surgical pathologists and pathology trainees. However, pathologists with specialty expertise might also benefit from emphasis on common diagnostic challenges encountered during intraoperative consultations.

Upon completion of this educational activity, participants should be able to:
1. Recognize frozen section artifacts and avoid sampling errors that can influence diagnosis
2. Develop an algorithmic, pattern-based approach to gland-forming hepatic nodules
3. Discriminate between carcinoma and its mimics in frozen sections, particularly in neoadjuvantly treated patients
4. Appropriately classify pulmonary neoplasms and identify problems in their differential diagnoses
5. Communicate results to clinicians effectively and understand immediate clinical implications of rendered diagnoses
