Objectives
This 2-day Course in Thyroid Tumors will consist of
– Lectures alternating with discussions of cases.
–  Access to the  Slide seminar and to the PowerPoint presentations
After the completion of the session, participants will be able to:
1. Know the changes in the 2023 WHO Classifications of Thyroid neoplasms and 2023 Bethesda System and understand the interest of these changes.
2. Describe and diagnose the common types of well-differentiated (papillary and follicular; invasive or circumscribed growth pattern; low grade and high grade), poorly differentiated and undifferentiated carcinomas, as well as medullary carcinoma
3. Make the differential diagnosis of the major types of encapsulated follicular patterned tumours – follicular adenoma, follicular variant of papillary carcinoma and minimally invasive follicular carcinoma – Understand and learn to utilize the following diagnostic terms: follicular tumour of uncertain malignant (FT- UMP), well-differentiated tumour of uncertain malignant (WDT-UMP), andNoninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP).
4. Understand and learn to utilize the criteria for vascular invasion, lymphatic invasion and capsular invasion (and to avoid the term “lymphovascular” invasion).
5. Understand and learn to utilize immunohistochemical and molecular markers for diagnostic and prognostic/predictive purposes in the field of thyroid pathology.

Participants are strongly encouraged to send interesting virtual cases (1 or 2)  svs or ndpi files  in advance, deadline later indicated,  (rather than bringing slides) for interactive discussion. Please send them via Wetransfer free until 2 Go.
