The fusion was not observed in PTC variant forms (13 cases), in follicular thyroid carcinomas (11 cases), in poorly differentiated carcinomas (5 cases), in oncocytic thyroid carcinomas (5 cases) or in benign lesions including follicular thyroid adenoma (10 cases) and oncocytic thyroid adenoma (15 cases).
