Demographic, clinical, laboratory, ultrasonographic, and cytological features of patients with Hashimoto's thyroiditis: results of a university hospital of 769 patients in Turkey.
We investigated the demographic and clinical features of patients with Hashimoto's thyroiditis who had been diagnosed and treated in Ege University, the main referral center in the Aegean region of Turkey. Medical records of patients who had been followed in the endocrinology clinic of Ege University were retrospectively evaluated. Patients who had been diagnosed as having any thyroid disorder were determined. Patients with Hashimoto's thyroiditis were selected among those patients. Seven hundred and sixty-nine patients fulfilled diagnostic criteria for Hashimoto's thyroiditis (725 females, 44 males; mean age 41.76 ± 12.49 years). 62.7% of patients were between 30 and 50 years of age. 53.3% of females and 63.6% of males had diffuse enlargement of the thyroid gland. TSH level was above 4.0 IU/l in 25.6% of females and 27.4% of males. Anti-tyroglobulin antibody was positive in 92% of females and 93.2 % of males. Anti-thyroid peroxidase antibody was positive in 98.4 % of females (713 patients) and 100% of males. Thyroid ultrasonography demonstrated single nodule in 52.2% and multiple nodules in 11.3% of female patients; and single nodule 32% and multiple nodules in 20% of male patients. Fine-needle aspirations of the nodules were performed in 207 patients, and none of those biopsies was diagnosed as malignant. Women with suspicious biopsis were operated. After surgery, we found that, 2% (n = 4) of patients with FNAC diagnosis of suspicious biopsies were papillary carcinoma and the other patients (3% (n = 6)) were lymphocytic thyroiditis. Age and sex distribution and laboratory findings of our patients were comparable to the previous reports. Nodule formation was the most common ultrasonographic finding in our patients, probably due to pseudonodularity. We found four women patients with thyroid cancer in our population.
