BACKGROUND Although thyroid fine-needle aspiration (FNA) and core needle biopsy (CNB) are commonly utilized modalities in the evaluation of thyroid nodules, metastatic tumors to the thyroid are only rarely encountered. We aspired to determine the incidence and primary origin of metastases to the thyroid at our institution and to examine their clinicopathologic and cytomorphologic features. MA...

BACKGROUND Fine-needle aspiration (FNA) of the thyroid is a widely accepted confirmatory test for thyroid cancer with high sensitivity and specificity. FNA is a simple procedure that is learned by many clinicians to enable accurate diagnosis of thyroid cancer. However, it is assumed that because the FNA test is a relatively simple procedure, its cytologic results are reliable regardless of the ...

Background and Objective: Nodular fasciitis (NF) is a self-limiting, transient neoplasm composed of fibroblasts and myofibroblasts. Since it regresses spontaneously, diagnosis by fine needle aspiration (FNA) cytology plays a major role in its management. Methods: We present a series of 8 cases with either FNA or biopsy diagnosis of NF, and study the major...

Rationale and Objectives. To compare the sensitivities of ultrasound guided core biopsy and fine needle aspiration (FNA) for detection of axillary lymph node metastases in patients with a current diagnosis of ipsilateral breast cancer. Materials and Methods. From December 2008 to December 2010, 105 patients with breast cancer and abnormal appearing lymph nodes in the ipsilateral axilla consente...

BACKGROUND Fine needle aspiration (FNA) of thyroid nodules is a cornerstone of surgical decision making in thyroid cancer. The most widely utilized system for reporting thyroid FNA results is the Bethesda System, which includes predicted malignancy rates for each FNA category. To date there have been few studies to determine whether these predictions are widely applicable. METHODS All thyroid...

Current preoperative diagnostic procedures for thyroid nodules rely mainly on the cytological interpretation of fine-needle aspirates (FNAs). DNA microarray analysis has been shown to reliably distinguish benign and malignant thyroid nodules in surgically resected specimens, but its diagnostic potential in thyroid FNA has not been examined. In the present study, the expression profiles of 50 be...

OBJECTIVE To assess the value of ultrasonography (US) combined with fine-needle aspiration (FNA) cytology for the investigation of lymph node metastases in patients with head and neck cancer. DESIGN Comparison of clinical examination (palpation) and preoperative US-FNA examination results of cervical nodes in a sample of patients with head and neck cancer. The histological features of the nec...

Our aim was to assess malignancy risk in adenomatoid nodules and suspicious follicular lesions of the thyroid obtained by fine needle aspiration (FNA) cytology. Retrospective research was performed of 276 patients who underwent thyroid surgery after preoperative ultrasound-guided FNA diagnosis of either adenomatoid nodule, cellular follicular lesion, "suspicious for follicular neoplasm" or foll...

PURPOSE Surgical resection as part of a multimodality approach in malignant pleural mesothelioma (MPM) has a high morbidity and mortality. Because mediastinal lymph node (MLN) metastases are a negative prognostic factor, preoperative staging is of paramount importance. Transesophageal endoscopic ultrasound with real-time guided fine needle aspiration (EUS-FNA) enables accurate MLN staging in lu...

BACKGROUND Transthoracic fine needle aspiration (FNA) cytology and core needle biopsy (CNB) are two commonly used approaches for the diagnosis of suspected neoplastic intrathoracic lesions. This study compared the diagnostic accuracy of FNA cytology and concurrent CNB in the evaluation of intrathoracic lesions. MATERIALS AND METHODS We studied FNA cytology and concurrent CNB specimens of 127 ...
