Thyroid metastases from lung cancer are very rare. A woman aged 42 years with a tumour in the lower lobe of the right lung was diagnosed as having lung adenocarcinoma positive for echinoderm microtubule-associated proteinlike 4-anaplastic lymphoma kinase. Positron emission tomography demonstrated fluorodeoxyglucose accumulation in the lower lobe of the right lung, the right thyroid lobe and bot...

The aim of this study is to establish efficacy of FNAb of thyroid nodules. This retrospective study was carried out from January 2007 to June 2013. Total of 487 cases were studied who had ultrasound guided thyroid FNA biopsy. The diagnostic yield of initial FNAb was 82.6%, with two out of 13 indeterminate lesions turned out malignant. Sensitivity, specificity, positive predictive value and nega...

We report a case of large iris melanocytoma in a child diagnosed by fine needle aspiration biopsy. In this interventional case report, cytologic features typical of melanocytoma were obtained by fine needle aspiration biopsy (FNAB). FNAB can be used in difficult diagnostic cases if a good sample is obtained, this technique has an accuracy of more than 99% in tumors larger than 3 mm; however, fa...

FNAB is a safe, simple and quick method of early preoperative diagnosis of chordoma. However, because of various overlapping cytologic features between chordoma, chondrosarcoma and metastatic clear cell carcinoma, it is important to recognize the various appearances of chordoma in FNAB [6,7]. The cytologic features, combined with classic radiologic and clinical presentations, allow for correct ...

Aims of this commentary is to report the most recent views about epidemiology, diagnostic procedures, malignancy risk factors and clinical management of thyroid nodules in children. On the basis of our personal experiences and recent literature evidences, we conclude that: a) if nodule is accompanied by lymphadenopathy and/or other alert findings, fine-needle aspiration biopsy (FNAB) should be ...

We reviewed 43 fine-needle aspiration biopsy (FNAB) smears with abundant extracellular mucinous material to determine whether accurate classification of mucinous lesions is achievable on FNAB: 26 had carcinoma (pure colloid carcinoma [CCA], 23; mixed CCA/invasive ductal carcinoma [IDC], 3); 17 had benign lesions on follow-up (benign MLL, 6; fibrocystic change [FCC], 6; myxoid fibroadenoma [MFA]...

We describe the cytologic features of chondromyxoid fibroma in fine-needle aspiration biopsy specimens in 4 patients. We analyzed rapid Romanowsky– and Papanicolaou-stained slides with a respect to overall cellularity, the presence of hypercellular chondromyxoid fragments (HCFs), nuclear atypia, cytoplasmic features, and the presence of giant cells. The most consistent and diagnostically useful...

BACKGROUND The objective of this study was to compare the utility of Thin-Prep (TP) cytologic preparation with that of Cell Block (CB) preparation in the diagnosis of thyroid lesions, mainly follicular epithelial lesions, by fine needle aspiration biopsy (FNAB). Feasibility of using the TP slides for immunocytochemical stains is also discussed. METHODS A total of 126 consecutive cases of thyr...

BACKGROUND AND PURPOSE Malignancy correlates with hardness of tissues and US elastography can potentially analyze the stiffness of lesions. Our aim was to evaluate the utility of US elastography in the detection of malignant nodules and to investigate interobserver agreement with this technique. MATERIALS AND METHODS One-hundred three consecutive patients with 106 thyroid nodules were examine...
