Fine-needle thyroid aspiration biopsy has a 20-year history in Scandinavia but has seen little use in North America owing to concern about the dissemination of malignant disease and the more limited use of aspiration cytology in general. We have reviewed our experience with this method in 103 cases, and on the basis of our work and the accumulated evidence of others, believe that the procedure ...

In the majority of cases, fine needle aspiration biopsy of the pancreas is used to confirm or exclude the presence of malignancy. New therapeutic trials need a precise diagnosis before treatment. Material consists of smears, microbiopsy and monolayer cytology. Microbiopsies and monolayer cytology can also be used for complementary techniques. The sensitivity of the technique is better for solid...

Fine needle aspiration biopsy of lymph nodes using a 19 gauge needle and Luer Lok syringe was performed in 59 cases. This was compared with histological diagnosis and an accuracy of 93.2% was achieved. This method is simple and is highly acceptable among patients. It is a very useful technique where a biopsy of lymph node is not possible (JPMA 30:267, 1980).

We have previously shown that cytological diagnosis based on fine-needle aspiration biopsy (FNAB) is a safe and efficient method for the discrimination between benign, primary malignant and metastatic bony lesions. We have now studied metastatic lesions to assess the diagnostic accuracy and to ascertain whether FNAB allows identification of the primary lesion. Between 1990 and 1997, 447 patient...

Fine-needle aspiration (FNA) of inflammatory and neoplastic head and neck masses has become a widely used procedure in otolaryngology-head and neck surgery. Using both subjective (patient perception) and objective (complication rate, accuracy) criteria, this prospective study evaluated patients undergoing FNA with and without anesthesia. Seventy-five patients were enrolled into 1 of 3 study gro...

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...

OBJECTIVES The exact preoperative diagnosis of parotid gland masses requires highly specific and sensitive diagnostic techniques. The specificity, sensitivity and accuracy of ultrasonography guided fine needle aspiration biopsy of parotid gland masses were assessed. PATIENTS AND METHODS There were 46 female and 36 male patients. The mean age was 39 years (range 18 to 74 years). Ultrasonograph...
