Because of the widespread use of Thyroid ultrasonography, many Thyroid lesions can be early detected. The next step is making the diagnosis by FNAC and under ultrasonography-guided, if there are multiple lesions, or the lesion is small, for the differential diagnosis of benign from malignant lesions. In the cytology, the Thyroid cancers of follicular epithelial cell include well-differentiated and undifferentiated (anaplastic) carcinomas. Well-differentiated Thyroid carcinomas include papillary carcinomas (PTC, 80- 90%), and follicular carcinomas (5-10%). Non-follicular Thyroid carcinomas include Medullary Thyroid Carcinomas (10%) and lymphomas (1-2%). Usually, the diagnosis is easy to be determined in the experienced doctors. The difficulty occurs only in the differential diagnosis of malignant from benign follicular lesions. The planning of the management of Thyroid cancers, especially papillary Thyroid cancers, is quite different from the guideline used previously. On the other hand, for the quality of life, early detected Thyroid lesions with low risk and good prognosis should be managed more conservatively, e.g. just lobectomy is performed. For the undetermined lesion by FNAC, the planning should be also different from those with definite diagnosis preoperatively. It is much safe if Thyroidectomy can be done to have pathological proof. The morphological characteristics of each type of Thyroid cancers will be demonstrated. Finally, three examples with complete different management after ultrasonography and ultrasonography-guided FNAC are also depicted.
