Cytologic Mimicry and Masquerade
The Diagnostic Cytology Seminar is one of the highlights of our Annual Scientific Meeting, where an expert panel of cytologists discuss their diagnostic process for “unknown” cases selected by moderators. The seminar has a rich history of being an educational as well as engaging session, making it an enduring favorite among attendees.
In celebration of the combined meetings of the International Academy of Cytology (IAC) and the American Society of Cytopathology (ASC) this year, we are thrilled to feature an All-Star team of past presidents and leaders of the IAC and ASC as our expert panelists for the 2022 Diagnostic Cytology Seminar.
This is your chance to test yourself and generate a differential diagnosis for each case prior to hearing the panelists’ perspectives and the final diagnoses at the seminar. Come join us at the seminar – we look forward to seeing you all there!
