Subacute granulomatous (De Quervain's) thyroiditis: Fine-needle aspiration cytology and ultrasonographic characteristics of 21 cases.

Background: Subacute granulomatous thyroiditis (SGT) is an inflammatory disease that presents with different clinical and cytological characteristics. Although the diagnosis is generally made clinically, imaging methods and fine-needle aspiration (FNA) may provide assistance, particularly in atypical cases. The objective of this study is to reveal the ultrasonographic (USG) and cytological characteristics of SGT.

Malignancy rate in nondominant nodules in patients with multinodular goiter: Experience with 1,606 cases evaluated by ultrasound-guided fine needle aspiration cytology.

Background: Conventional medical sources recommend the use of fine needle aspiration cytology (FNAC) for single thyroid nodules and the dominant nodule in multinodular goiter (MNG). The purpose of the present study was to analyze the utility of FNAC for multiple thyroid nodules in patients with MNG and to determine the rate of malignancy in teh nondominant nodules.

Materials And Methods: Our private practice performed ultrasound-guided FNAC on 1,606 patients between February 2001 and February 1, 2010.

Cervical lymphadenopathy associated with Hashimoto's thyroiditis: an analysis of 22 cases by fine needle aspiration cytology.

Objective: To analyze the possible association between Hashimoto's thyroiditis (HT) and cervical lymphadenopathy in cases diagnosed by fine needle aspiration cytology.

Study Design: Among the patients referred to our laboratory for ultrasound-guided fine needle aspiration cytology of thyroid nodules (USG-FNAC), cases of HT associated with cervical lymphadenopathy were evaluated.

Results: Between February 2001 and May 2007, HT was diagnosed in 94 (11%) of a total of 856 thyroid USG-FNAC cases.
