FINE NEEDLE ASPIRATION BIOPSY (FNAB) OF THE THYROID GLAND IN CHILDREN AND ADOLESCENTS

Between 1981 and 1989, 2000 patients with thyroid nodules underwent fine-needle aspiration biopsy (FNAB) at the Hospital do Servidor Publico Municipal de Sao Paulo; out of them, 53 were children and adolescents. The ages varied from 7 to 20 years old, with a mean age of 15 years old; 50 (94,3 %) were female and 3(5,6 %) were male.The cytologic findings showed 20 follicular patterns, 13 inflammatory patterns (10 Hashimoto's thyroiditis, 2 suppurative thyroiditis and 1 Lymphocitic), 6 hemorrhagic cysts, 3 epidermoid cysts, 2 papillary patterns and 3 Hürthle patterns. In 6 cases, the cytological material were unsatisfactory.2 cases of Papillary Carcinoma and 1 Hürthle neoplasm diagnosed in the cytology has histological confirmation. No false positives or negatives were reported.In conclusion, in despite of limitations of the technique, the FNAB provides the clinician a more direct information about thyroid lesion and it is helpful for the evaluation of thyroid nodules in chiIdhood.
