OBJECTIVES Fine-needle aspiration biopsy (FNAB) has a well-established role in the evaluation of an adult head and neck mass (HNM) but remains underused in children. The objectives of this study were to assess the diagnostic accuracy, safety profile, use of anesthesia, and influence on surgical decision making of FNAB of HNM in the pediatric population. STUDY DESIGN Case series with chart rev...

Fine needle aspiration biopsy (FNAB) was performed in 46 patients with an orbital mass. Positive cytological identification was made in 43 biopsy specimens. In 26 cases with histopathological control the accuracy was 81%. In experienced hands FNAB is safe and appears to be a valuable tool in establishing a diagnosis of malignancy in orbital tumours.

We investigated if the use of two tumor markers, galectin-3 and CD44v6, could improve diagnostic accuracy of thyroid fine needle aspiration biopsy (FNAB) in cytologically indeterminate lesions (CIL). 351 patients with CIL [cellular follicular lesion/suspicious follicular neoplasm/suspicious Hürthle cell neoplasm (CFL/sFN/sHCN), Hürthle cell neoplasm (HCN), and follicular neoplasm (FN)] and surg...

BACKGROUND Even after needle biopsy, the preoperative differential diagnoses of intracystic tumors of the breast are challenging because of their nonspecific radiological characteristics and subtle cytological and histological appearance. The aim of this study is to investigate a novel diagnostic method, targeting genomic instability (GIN) in intracystic tumors of the breast, using tumor DNA fr...

Introduction Warthin tumour (WT) represents the second most common benign parotid neoplasm. The aim of this study is to evaluate utility FNAB in preoperative diagnosis and treatment decision patients with WT.

The objective of the current study was to evaluate the sensitivity, specificity and accuracy of fine needle aspiration biopsy (FNAB) of submucous nodules from the oral cavity and head and neck region as an auxiliary diagnostic tool. Fifty patients with nodule lesions in the oral cavity and the head and neck region were selected. All of them were submitted to FNAB and to either incisional or exc...

Although ultrasonography (US)-guided fine-needle aspiration biopsy (FNAB) is the most reliable diagnostic modality for evaluating thyroid nodules, 10% to 40% of FNAB samples yield indeterminate findings. The BRAF V600E mutation, a highly specific molecular marker for papillary thyroid carcinoma (PTC), well known for its prognostic value, has dubious diagnostic value because of its low sensitivi...

AIM To assess the feasibility and diagnostic accuracy of endoscopic ultrasound guided fine needle biopsy (EUS-FNAB) in patients with solid pancreatic masses. METHODS Ninety nine consecutive patients with pancreatic masses were studied. Histological findings obtained by EUS-FNAB were compared with the final diagnosis assessed by surgery, biopsy of other tumour site or at postmortem examination...

OBJECTIVE Diagnosis of axillary nodal involvement is significant in the management of breast cancer as well as in predicting prognosis. In this prospective study, we evaluated the efficiency of US-guided fine needle aspiration biopsy (FNAB) in preoperative axillary staging of early breast cancer. MATERIAL AND METHODS Between January 2011 and July 2013, 46 women were prospectively enrolled in ...

OBJECTIVE To analyze the potential sources of diagnostic errors and overall accuracy rate of the fine needle aspiration biopsy (FNAB) diagnosis of cystic salivary gland neoplasms. STUDY DESIGN A 10-year (1993-2002) retrospective review of the cytopathology slides from the Division of Cytopathology, Department of Pathology, Long Island Jewish Medical Center, New Hyde Park, New York, identified...
