In this study for determination the efficacy of needle aspiration which is done both prospectively and retrospectively , two independent pathologists studied blindly the cytologic smear of F.N.A of 75 female patients with breast mass (the mean ages were 50.5 years). &nbs...
BACKGROUND According to current guidelines, transesophageal ultrasound-guided fine needle aspiration (EUS-FNA) can be performed as an alternative for surgical staging to confirm mediastinal metastases in patients with non-small cell lung cancer (NSCLC). To date however, data regarding the routine use of EUS-FNA in the preoperative staging of unselected patients with NSCLC are limited. AIMS AN...
Background: Fine needle aspiration (FNA) is the most important method in the diagnosis of thyroid nodules before surgery. Recently, the efficiency of FNA in thyroid nodule management has been debatable. On the other hand, intraoperative frozen section (FS) has been used to confirm the diagnosis of FNA and select the proper surgical approach. In this regard, the present study aimed to assess the...
BACKGROUND Follicular thyroid carcinoma cannot be distinguished reliably from benign follicular neoplasia by fine needle aspiration (FNA) biopsy. Given an estimated 20% risk of malignancy, many patients with indeterminate FNA biopsies require thyroidectomy for diagnosis. Some centers have shown significant discordance when a second pathologist evaluates the same FNA biopsy. We sought to determi...
Background Fine needle aspiration (FNA) is considered the investigation of choice in cytological sampling of thyroid nodules. Non-aspiration fine needle cytology (NAC) has been described as an alternative method with technical and interpretive advantages. This study compares the sampling adequacy and diagnostic accuracy of NAC with FNA in predicting neoplasia and malignancy in thyroid nodules. ...
To compare the value of cytokeratin fragment 21-1 (CYFRA 21-1) concentration in the fine-needle biopsy aspirates (fine needle aspirate [FNA] CYFRA 21-1) with cytopathology of fine-needle aspiration biopsy (FNA cytology) and to assess whether CYFRA 21-1 concentrations from ultrasound-guided fine-needle aspiration biopsy (US-FNAB) specimens (FNA CYFRA 21-1) is not inferior to FNA cytology in the ...
علی رغم فراوانی بیماری سل در جهان , سل پستان هنوز بیماری نادری است که به طور عمده با تظاهراتی شبیه توده یا زخم و ترشح پستان خود را نشان می دهد. بیشتر موارد سل پستان از مناطق آندمیک مانند هندوستان , بنگلادش و آفریقای جنوبی گزارش شده اند. در کشور ما نیز با وجود شیوع نسبی سل , موارد سل پستان به صورت پراکنده گزارش شده است. لذا در برخورد با بیماران مبتلا به توده , زخم و سینوس پستان باید به فکر این ب...
Fine needle aspiration biopsy(FNAB) and core needle biopsy(CNBx) have proved to be accurate and cost-effective techniques for diagnosis of inflammatory and neoplastic lesions at different body sites. However, their applicability in bone and soft tissue pathology is still controversial. In this study, our experience with FNAB and CNBx of musculoskeletal lesions was prospectively investigat...
Ultra sound due to its safety, low cost and ease of performance is the primary method of choice in liver imaging. In addition, at present time, real time sonography appears to be one of the most accurate guided technique for liver biopsy. This study was undertaken to evaluate the value of sonographically guided fine needle aspiration cytology ( FNAC) in diagnosis of foc...
BACKGROUND At present only few studies directly compare the diagnostic yield of endobronchial ultrasound guided fine needle aspiration (EBUS-FNA) and transcervical video-assisted mediastinoscopy (TM) for mediastinal lymph node staging in patients with NSCLC. If and when EBUS-FNA may replace TM as Gold Standard remains controversial. METHODS From April 2008 to December 2009, 36 patients with m...
