Background and Objectives: Thyroid gland because of its superficial location is amenable to direct physical examination. Clinical assessment of thyroid lesions by means of physical examination, thyroid scans and ultrasonography is not completely reliable. Fine needle aspiration cytology (FNAC) is the most cost-effective, safe and an initial diagnostic test in the pre-operative evaluation of thy...

background and objectives:breast cancer is the most common cancer among women worldwide. fine needle aspiration biopsy (fnab) is one of the methods of breast biopsy which is fast, easy and cost effective. the aim of this study was to evaluate the concordance rate between pathologic results of sonography or stereotaxy guided fnab and guided core needle biopsy (cnb) in the evaluation of breast le...

The aim of this study was to evaluate the role of fine needle aspiration cytology in the diagnosis of abdominal and retroperitoneal masses in children on this study. In 53 cases of childhood abdominal and retroperitoneal masses within a 4 year period (1998- 2001) preoperative fine needle aspiration was done under the guide of CT scan. 2 pathologists reviewed fine needle aspiration smears. I...

background & objective: chronic non healing ulcers or scar undergoing malignant transformation is a rare phenomenon with an estimated incidence of 2%. though, numerous predisposing factors have been identified, still it is rarely diagnosed and commonly mistaken for a benign condition. the objective of this study was to verify the efficacy of the fine needle aspiration cytology/ scrape cytol...

background: endosonography is a distinct method in evaluating gastrointestinal (gi) structural lesions, particularly in the pancreatobiliary system. this procedure has made a fundamental change in the diagnosis of pancreatic mass lesions through fine needle aspiration (fna). this study aims to evaluate the results and efficacy of endosonographic fine needle aspiration (eus-fna) in patients pres...

introduction: the preoperative diagnostic evaluation of the parotid lesion is a valuable aid in planning the operation and the approach to intervention. among different diagnostic tools, fine needle aspiration has a key role. however, the exact efficacy of this technique in our center had not been thoroughly investigated. materials and methods: between january 2000 and june 2007 a subset of 64 ...

purpose : fine needle aspiration (fna) cytologic findings of langerhans cell histiocytosis (lch) have been well described, but using this method in the diagnosis of orbital lesions is a recent experience. we hereby report two cases of orbital bone lch diagnosed by fna that later was confirmed by routine h&e; histopathology and immunohistochemistry (ihc) methods. case reports : the first case wa...

in riedel’s thyroiditis, a rare chronic inflammatory disease of thyroid gland, fine needle aspiration is usually non-diagnostic because most often only follicular cells are obtained and not the fibrous material characteristic of this type of thyroiditis. therefore the diagnosis is often only established by histopathologic study of the surgically obtained biopsy. the illustrated case is a 46-yea...

background and objective: fine needle aspiration cytology (fnac) is well accepted as a useful diagnostic technique in the management of adult patients with head and neck lumps. but, until recently, very few reports have been obtained regarding the role of fnac in nonthyroidal neck masses in children. hence, the objective of our study was to determine the diagnostic value of fine needle aspirati...
