The prevalence in the general population being 1 to 2 cases per million. However, recents studies have demonstrated an increase of TSH-omas over time. The increased number of cases principally results from the ultrasensitive TSH immunometric assays and from improved general practioner endocrinologist awaress.

Introduction: Papillary thyroid cancer (PTC) has an excellent prognosis in most cases with a 10-year survival rate of more than 95% but decreases drastically in cases of PTC iodine-refractory, in recurrent and/or metastatic disease. Tyrosine kinase inhibitors, such as lenvatinib or sorafenib, have been approved in such cases and in some cases are able to stabilize the disease and prolong survival. However, serious side effects have been reported such as fistula formation, blee...
