BACKGROUND/AIM To investigate the reliability of fine-needle aspiration biopsy (FNAB) in thyroid nodules and benign/malignant discrimination, particularly in large nodules. MATERIALS AND METHODS A retrospective analysis of 1466 nodules in 402 patients with thyroid nodules who underwent thyroid surgery was made. The pathologic results of the thyroid nodules from preoperative FNAB and postopera...

To identify the diagnostic accuracy of imaging, fine need aspiration biopsy (FNAB) and core needle biopsy (CNB) in identifying papillary lesions in the setting of a population based mammographic screening program. A retrospective analysis of mammographic screening detected lesions diagnosed as papillary lesions on surgical excision at Breast Screen Sydney West between 1993 2010 was performed. I...

for the diagnostic work up of thyroid nodules (1). It has proven to be a safe, reliable and effective tool over many years (2, 3). FNAB of the thyroid gland sometimes causes a hematoma; this is the most commonly encountered complication (4). Most hematomas that occur after a FNAB are self-limiting, they cause only minimal pain and some times they cause mild neck swelling. There have been severa...

Fine-needle aspiration biopsy (FNAB) is an accurate, cost-effective method of evaluating lymphomas. The neutrophil-rich variant of anaplastic large cell lymphoma (NR-ALCL) is a rare non-Hodgkin lymphoma. To our knowledge, we present thefirst study of NR-ALCL by FNAB cytology. Histologic confirmation was available for both patients. Both cases were positive for Ki-1 (CD-30) and were either T-cel...

US-Fine needle aspiration biopsy (US-FNAB) is a simple diagnostic procedure to find malignant thyroid nodules. However, few papers have evaluated the specific value of FNAB to detect medullary thyroid cancer (MTC). This study aimed to appraise the value of FNAB cell blocks in the diagnosis of MTC by a novel cell block preparation method. We retrospectively reviewed four typical cases of MTC tha...

The role of fine-needle aspiration biopsy (FNAB) for the diagnosis of palpable breast masses has been a hotly debated topic since the 1980s. Despite well-executed studies from highly qualified centers demonstrating the diagnostic efficacy of FNAB,1,2 in the United States this technique has largely been replaced by core biopsy (CB) as the primary method for percutaneous sampling of both palpable...

BACKGROUND The diagnosis of thyroid follicular carcinoma by fine needle aspiration biopsy is a well known problem in thyroid pathology. METHODS We evaluated telomerase activity (TA) in 85 fine needle aspiration biopsy (FNAB) samples from patients with thyroid nodules. Surgery samples from patients with tumor or follicular adenomas were also analyzed. RESULTS Twenty of the FNAB samples corre...

BACKGROUND Fine needle aspiration biopsy (FNAB) is an accurate test commonly used to determine whether thyroid nodules are malignant in adults. However, less is known about its diagnostic accuracy for this purpose in children, where conduct of FNAB is less frequent, more technically challenging, and pre-test probabilities of malignancy are often higher. The purpose of this systematic review is ...
