Fine-needle aspiration biopsy for the diagnosis of breast lesions has been used for more than six decades and has been established as an effective procedure in Europe for many years. In order to evaluate the accuracy of fine-needle aspiration with histopathologic confirmation, a retrospective study was performed in Iranian Center for Breast Cancer, using a computer database over one year period...
The cytological features of testicular germ cell tumours were established in smears from 15 freshly resected tumours. These features were applied to the fine needle aspiration cytology diagnosis of metastases in 27 patients referred for chemotherapy. There were 16 positive reports in 32 aspirates of which 13 were taken before chemotherapy and three in patients with residual or new masses after ...
Background and Purpose: Thyroid dysfunctions are one of the most important diseases in endocrinology. Fine needle aspiration (FNA) is currently the first line diagnostic tool for the evaluation of thyroid nodules. The adequacy of specimens provided by this method is also very important. FNA puncture in thyroid causes intra- parenchyma hemorrhage, which may distribute the quality of tissue spe...
Objective: To determine the satisfactory sampling rate and safety of free hand fine needle aspiration cytology (FNAC) and ultrasound-guided sampling of thyroid gland. Methodology: This comparative cross-sectional study was conducted at the department of surgery and department of ENT & head and neck surgery of Saidu Teaching Hospital from January 2008 to December 2010. A total of 212 thyroid sam...
Background: Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) is one of the few techniques which can obtain cells and tissue from the liver and pancreas. However, the technique remains vulnerable to poor specimen quality and sampling error. Objectives: To evaluate the ability of a high-resolution microendoscope (HRME) to visualize the cellular and architectural features of normal an...
This paper presents cytomorphological features of the histoid variety of lepromatous leprosy. Fine needle aspiration of a lepromatous nodule showed cytological features consistent with those of histoid leprosy. Simultaneously, a biopsy of the nodule was also performed and the case confirmed as histoid leprosy. The advantages of the fine needle aspiration technique are that it is simple, quickly...
Endoscopic ultrasound (EUS)-guided tissue acquisition is an indispensable technique for the diagnosis of many diseases of the gastrointestinal tract and adjacent structures. EUS-guided fine-needle aspiration (EUS-FNA) is known for its high accuracy and low complication rate. However, the outcome of EUS-FNA highly depends on several factors such as the location and characteristics of the lesion,...
Conventional transbronchial fine needle aspiration (TBNA) B < Conventional transbronchial needle aspiration (TBNA) is a safe technique and should be used to sample mediastinal and hilar lymphadenopathy during initial diagnostic bronchoscopy where a pre-procedure CT scan has demonstrated significant adenopathy. < Conventional TBNA is a safe technique for sampling hilar and mediastinal lymph node...
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. in al...
