Thyroid tumors are rare, often difficult to classify. A new WHO classification was established in 2017, which totally changes the diagnostic criteria in many cases.

Thyroid pathologists are confronted to the difficult challenge to classify follicular thyroid nodules between : benign adenoma, papillary carcinoma, follicular carcinomas and the very tricky “encapsulated follicular-patterned thyroid tumors” with all the differential diagnosis.

Why refer cases for a second opinion ?

With the new thyroid classification of thyroid tumors, the pathologists are often uncertain of their diagnosis between benign, malignant or tumors of uncertain malignant potential.

It’s crucial for the patient to differentiate properly these entities as the management, the treatment, the prognosis could be totally different.
