BACKGROUND Core needle biopsy is a relatively new technique used to diagnose salivary gland lesions, and its role in comparison with fine needle aspiration cytology needs to be refined. METHODS We compared the results of 228 ultrasound-guided core needle biopsy and 371 fine needle aspiration procedures performed on major salivary gland tumors with their postoperative histological diagnoses. ...

This retrospective study was undertaken to evaluate the diagnostic usefulness of 244 sonographically guided fine- needle aspiration biopsy in 226 patients with ultrasonographically suspected hepatic malignant lesions. A final diagnosis of malignancy was established in 166 cases (73%) (145 hepatocellular carcinoma, 21 metastasis); benign lesions were aspirated in 60 cases (27%). The diagnostic s...

Implantation of cancer cells from needle biopsy has been reported in a wide range of malignancies. Fine needle aspiration biopsy has become an accepted method for assessment of thyroid nodules. Local reappearance of thyroid cancer from needle track dissemination is a rare complication of thyroid aspiration. A 45-year-old female developed local recurrence of papillary thyroid carcinoma four year...

BACKGROUND Fine needle aspiration is an accurate technique to diagnose metastatic melanoma. Few reports exist in the literature describing its usefulness in many patients with melanoma confirmed by open biopsy. OBJECTIVE The purpose of this study was to determine the utility and predictive value of fine needle aspiration in patients with malignant melanoma who presented with lesions suspected...

BACKGROUND Hitherto uncommon, the incidence of extracranial metastases of primary brain malignancies may increase, with improved treatment methods and longer patient survival. Fine needle aspiration biopsy is a simple, safe and reliable method to diagnose metastatic malignancy. It has definite advantages over tissue biopsy, which is more invasive and is of higher risk to the patient. Ours is a ...

BACKGROUND Approximately 30% of fine needle aspiration biopsies of the thyroid have inconclusive results. We conducted a prospective trial to determine whether clinical and molecular markers could be used in combination to improve the accuracy of thyroid fine needle aspiration biopsy. METHODS Clinical, tumor genotyping for common somatic mutations (BRAF V600E, NRAS, KRAS, RET/PTC1, RET/PTC3, ...

BACKGROUND Fine-needle aspiration breast biopsy has been used increasingly as an alternative to excisional biopsy. The purpose of this study is to evaluate the accuracy of fine-needle aspiration with histopathologic confirmation. METHODS A retrospective study was performed using a computer database over a 5-year period. All women who had had fine-needle aspiration breast biopsy with histopath...

In Riedel’s thyroiditis, a rare chronic inflammatory disease of thyroid gland, fine needle aspiration is usually non-diagnostic because most often only follicular cells are obtained and not the fibrous material characteristic of this type of thyroiditis. Therefore the diagnosis is often only established by histopathologic study of the surgically obtained biopsy. The illustrated case is a 46-yea...

56 malignant bone neoplasms (15 primary and 41 metastatic), diagnosed by fine-needle aspiration biopsy, are reported. 100% diagnostic accuracy was achieved. The results indicate that fine-needle aspiration biopsy can be a substitute for open surgical biopsy in selected cases.
