[Eco-guided fine needle aspiration of the thyroid. Algorithm diagnosis].

Fine needle aspiration (PAAF) of thyroid it has demonstrated to be highly sensitive and specific to establish a diagnosis and to implement the corresponding treatment, these qualities are increased when the guide ecográfica is used: fine needle aspiration of thyroid with ultrasonography guide (PAEAFT). 139 cases of PAEAFT are presented of whose material was carried out extended conventional and thin according to specific technique and they were colored with Haematoxylin and eosin (H & E)--Tint 15 (DIFF-QUIK) and Papanicolaou; analyzing their distribution for sex, age, topography, characteristic of nodules and cytologic diagnoses. The presumptive diagnoses corresponded to: Multinodular Goiter (21.58%)--Hashimoto's thyroiditis (2.87%)--Follicular neoplasm: Under degree (I-II): (57.57%), High degree (III): 2.15%--Hürthle cell tumors (2.87%)--Papilary carcinoma (4.32%). The prevalence corresponded to the female sex (93.52%). The pursuit of the patients was carried out based on the proposed algorithm, modified of that of Gharib, 1997.
