Non-Neoplastic and Indeterminate Thyroid Lesions

Non-neoplastic thyroid lesions include nodules with nondiagnostic cytology and those benign cytology. In approximately 15% of cases, fine-needle aspiration (FNAC) results in cytologically inadequate specimens. Nondiagnostic smears have an number cells to allow a diagnosis. This category also includes cystic lesions, which are frequent cause results. Benign diagnosis represents the most result following FNAC, rate 70%. The common macrofollicular or adenomatoid/hyperplastic nodules, colloid adenomas, nodular goiter, lymphocytic granulomatous thyroiditis. risk malignancy these two cytological categories is 1–4% 0–3%, respectively. management generally conservative. about 20–25% FNAC leads indeterminate nodule. clinical issue, since malignancy, although relatively low (up 30%), cannot be ruled out certainty. When indicated, surgery has diagnostic rather than therapeutic purpose, almost 80% procedures being unnecessary. this regard, it important emphasize that thyroidectomy can lead serious complications. For reasons, there increased emphasis on assessing minimize unnecessary surgical procedures.
