GONI E, Ignacio et al. Definitive anatomopathological findings in thyroidectomized patients with preoperative diagnosis of follicular neoplasm. Rev Chil Cir [online]. 2012, vol.64, n.2, pp. 128-132. ISSN 0718-4026.  doi: 10.4067/S0718-40262012000200004.

Background: The finding of follicular neoplasm, using a FNAP, is an indication for partial or total thyroidectomy, to obtain the definitive malignant or benign histology. Frequently, it is possible to identify significant additional histological diagnosis. Aim: To obtain the definitive histological findings in patients with follicular neoplasm by FNAP. Patients and Method: Transversal analysis of 133 patients that underwent to total thyroidectomy between 2003 and 2009, that filled de requirements for adequate histological assessment. Results: In 33.1% of the treated patients the final diagnosis was indeed a follicular neoplasm (adenoma in 26.3% and cancer in 6.8%). In the 51.9% the finding was follicular colloidal hyperplasia and other thyroid cancer in 8.3%. The total malignant prevalence in the whole gland was 29.3%. Conclusions: The thyroidec-tomy is the treatment of choice and the final diagnostic procedure for these patients. The histological findings of cancer different from follicular not only in the punctioned nodule are a secondary and an additional argument for reinforcing the surgical indication.
