Ultrasound-guided fine needle aspiration biopsy (FNAB) is currently used as an alternative combined modality, which enables accurate detection and evaluation of solid and cystic abnormal lesions. It's easily performed, with low cost and most effective as it decreases the number of unnecessary operational procedures; that take place to rule-out malignancy. The aim of this paper is to suggest the...

AIM To compare the efficacy of fine-needle non-aspiration cytology (FNNAC) with that of fine-needle aspiration cytology (FNAC) of thyroid lesions. MATERIALS AND METHODS FNAC and FNNAC techniques were studied in 50 cases of thyroid lesions. All the needle-sampling procedures were done by a single operator. The samples were assessed cytologically and evaluated using five parameters, that is, ba...

Fine needle aspiration cytology (FNAC) has established itself as a diagnostic modality in various visceral and soft tissue lesions. However its usage in the diagnosis of different bony lesions has not received much attention. Open surgical biopsy is considered as the procedure of choice for obtaining diagnostic tissue sampling of bone tumors (Kreicbergs et al., 1996). Apart from being an inpati...

585 Biopsy refers to tissue sampling for histological examination, diagnosis, classification, and grading of a tumor. The goal of biopsy is to obtain a diagnostic tissue sample without complications, tumor spread, and compromise of future treatments.1,2 As a rule, all lesions should be biopsied as if they were malignant,2,3 and all soft tissue masses 3 cm or larger in diameter or growing lesion...

When performing endoscopic ultrasound-guided fine needle aspiration (EUS-FNA), identifying neoplasia in the setting of chronic pancreatitis can be technically challenging. The morphology of an ill-defined mass on sonography, presence of calcifications or intervening collaterals, reverberation from a biliary stent, low yield of tissue procurement, and interpretative errors in cytopathology can r...

UNLABELLED Circulating tumor cells (CTC) harvested from peripheral blood have received significant interest as sources for serial sampling to gauge treatment efficacy. Nanotechnology and microfluidic based approaches are emerging to facilitate such analyses. While of considerable clinical importance, there is little information on how similar or different CTCs are from their shedding bulk tumor...

CONTEXT Tissue sampling of renal masses is traditionally performed via the percutaneous approach or laparoscopicaly. The utility of endoscopic ultrasound to biopsy renal lesions it remains unclear and few cases have been reported. OBJECTIVES To evaluate the feasibility and outcome of endoscopic ultrasound fine needle aspiration of renal tumors. METHODS Consecutive subjects undergoing attemp...

Endoscopic ultrasound-guided fine needle aspiration-biopsy is a safe and effective technique in diagnosing and staging of pancreatic ductal adenocarcinoma. However its predictive negative value does not exceed 50% to 60%. Unfortunately, the majority of pancreatic cancer patients have a metastatic and/or a locally advanced disease (i.e., not eligible for curative resection) which explains the li...

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...

conclusions the aspirates from the hypovascular and hypervascular sites of solid nodules are complementary and should be performed consecutively. results when only hypervascular site was used, adequate sampling was limited to 65% of the cases. when both sites were evaluated together, overall adequate sampling was 91%. adding a sample from the hypervascular site to hypovascular aspirate increase...
