Hallazgos anatomopatológicos definitivos en pacientes tiroidectomizados con diagnóstico preoperatorio de neoplasia folicular

Abstract

Defi nitive anatomopathological fi ndings in thyroidectomized patients with preoperative diagnosis of follicular neoplasm Background: The fi nding of follicular neoplasm, using a FNAP, is an indication for partial or total thyroidectomy, to obtain the defi nitive malignant or benign histology. Frequently, it is possible to identify signifi cant additional histological diagnosis. Aim: To obtain the defi nitive histological fi ndings 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 fi lled de requirements for adequate histological assessment. Results: In 33.1% of the treated patients the fi nal diagnosis was indeed a follicular neoplasm (adenoma in 26.3% and cancer in 6.8%). In the 51.9% the fi nding 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 fi nal diagnostic procedure for these patients. The histological fi ndings of cancer different from follicular not only in the punctioned nodule are a secondary and an additional argu-ment for reinforcing the surgical indication.
