Fine needle aspiration biopsy is the cornerstone for cytologic evaluation of thyroid nodules. Thyroid nodule prevelance increases with age, however there is no cytologic study exclusively from geriatric patients.

We examined the thyroid fine needle biopsy records taken from patients age 65 years or older between January 2006 and June 2009 at Dokuz Eylul University Hospital; and reviewed the cytological results of this group.

We analyzed 861 thyroid fine needle aspiration biopsy results from 642 patients 65 years or older. Mean age of patients were 71 (65–106) years. Sixty-nine percent of patients were female. Cytologic results were benign in 713 (82.8%), indeterminate in 25 (2.9%), malign in 7 (0.8%) and insufficient for diagnosis in 116 (13.5%) nodules. From the 26 nodules which had initially benign cytology, the final surgical pathology was benign in 23, malign in 3 nodules. From the 12 nodules which initially had indeterminate cytology, the final surgical pathology was benign in 8, malign in 4 nodules. Final surgical pathologies were malign in all of the nodules which had initially malign cytology (n: 5).

The female dominance in geriatric patients with thyroid nodules is similar with the general population. The occurrence of malign cytologies in geriatric patients is lower than that of the general population.
