Prostatic stromal sarcomas (PSS) are rare solid organ mesenchymal sarcomas. PSS may pose difficult diagnostic challenges on fine needle aspiration biopsy. We report a 48-year-old man diagnosed with metastatic high grade prostatic stromal sarcoma by a CT-scan guided fine needle aspiration (FNA) biopsy of a right lower lung lobe nodule. We reviewed the literature on the epidemiologic, cyto-histol...

OBJECTIVE Computed tomography-guided percutaneous fine needle aspiration biopsy of lung lesions is a simple, safe and reproducible procedure. Currently, it is widely used to diagnose lung lesions. However, different factors can influence the success rates of this procedure. The purpose of this study was to determine the influence of radiological and procedural characteristics in predicting the ...

Evaluation of thyroid nodules remains a challenge for primary care physicians. To include or exclude the presence of malignancy in a thyroid nodule, radioisotope scan, ultrasound, and fine-needle aspiration biopsy of the thyroid generally are used. The objectives of this study were to determine the utility and cost effectiveness of fine-needle aspiration biopsy of solitary thyroid nodules in a ...

Fine-needle aspiration biopsy is a diagnostic procedure used routinely in the evaluation of patients referred with a thyroid swelling. The technique and the results in our series of 233 patients, which included 39 carcinomas, are presented. A relatively high diagnostic specificity of 81% was found, whereas the diagnostic sensitivity was considerably lower (58%). It is concluded that fine-needle...

OBJECTIVE To compare the cost-effectiveness of fine-needle aspiration biopsy, iodine 131 scintigraphy, and ultrasonography for the initial diagnostic workup of a solitary palpable thyroid nodule. DESIGN A deterministic cost-effectiveness analysis was conducted using a decision tree to model the diagnostic strategies. SETTING A single, mid-Atlantic academic medical center. MAIN OUTCOME MEA...
