BACKGROUND Ultrasound-guided fine-needle aspiration biopsy (ultrasound-guided FNAB) is considered the diagnostic test of choice when a fine-needle aspiration biopsy (FNAB) returns an inconclusive diagnosis because of cytologic ambiguity or paucity of specimen. METHODS Cost-effectiveness analysis utilizing a decision tree was used to model the diagnostic strategies. The decision analysis model...

OBJECTIVES/HYPOTHESIS Pleomorphic adenoma (PA) is the most common, benign tumor of the major salivary glands. Surgical resection is the treatment of choice. Initial preoperative workup of major salivary gland neoplasms often includes fine needle aspiration biopsy (FNAB) and magnetic resonance imaging (MRI) of the head and neck. Our objective was to assess the positive predictive value of FNAB a...

Percutaneous fine-needle aspiration biopsy (FNAB) is a well-established and useful procedure in the diagnosis of lung squamous cell carcinoma (LSCC). Tumor seeding has been shown to be a potential risk. We report the case and management of a 78-year-old patient affected by LSCC who developed a chest wall metastasis in a straight line from the primary lesion along the FNAB needle track. Although...

BACKGROUND The low incidence of thyroid cancer despite the high prevalence of thyroid nodules necessitates a screening tool to determine which patients require surgical management. The utility of fine-needle aspiration biopsy (FNAB) for this purpose requires a low false-negative (FN) rate and an acceptable sensitivity and specificity for the detection of malignancy. While reviewing our institut...

BACKGROUND Lung cancer leads cancer-related mortality in the world. The objective of the present systematic review was to compare fine-needle aspiration biopsy (fnab) with core-needle biopsy (cnb) for diagnostic characteristics and yields for diagnosing lung cancer in patients with lung lesions. METHODS The medline and embase databases (from January 1, 1990, to September 14, 2009), the Cochra...

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...

Purpose: False negative results of fine needle aspiration biopsies (FNAB) remain one the most important problems in management thyroid nodules. The aim this study was to evaluate factors affecting false FNAB, especially nodules with indeterminate cytology.
 Materials and Methods: Patients who underwent FNAB subsequent thyroidectomy between January 2017 2020 were included study. performed o...

BACKGROUND Sarcoidosis is a prevalent disease of unknown cause characterized by granulomatous inflammation that often creates deep and/or superficial mass lesions. Tissue samples are considered the "gold standard" in diagnosis; however, it is a medically treated disease. We analyzed the utility and relative cost-effectiveness of fine-needle aspiration biopsy (FNAB) in the clinical investigation...

PURPOSE Establish an experimental model of metastatic melanoma primary culture cells from fine-needle aspiration biopsies (FNAB). METHODS Two metastatic melanoma primary culture cells from (FNAB) have been developed from patients who had been submitted to excision of metastatic lesions and they were identified by immunohistochemical analyses using S-100 and MB-45 melanoma markers. RESULTS T...

BACKGROUND Largely due to a lack of experience, familiarity, and/or confidence, few centers rely on simple fine-needle aspiration biopsy (FNAB) for the diagnosis of sarcomas and related tumors. METHODS The authors have reviewed their own experience in more than 200 cases of FNAB of bone and soft-tissue tumors, as well as cases reported in the literature. RESULTS FNAB has proven to be accura...
