INTRODUCTION Endoscopic biopsy techniques are useful in the diagnosis of sarcoidosis. There is a need for randomized trials to establish where these procedures fit in the diagnosis of sarcoidosis. OBJECTIVES The aim of the study was to compare the diagnostic yield of conventional transbronchial needle aspiration (TBNA) with endobronchial ultrasound-guided TBNA (EBUS-TBNA) and endoscopic ultra...

Subcutaneous tumor seeding after fine-needle percutaneous biopsy for hepatocellular carcinoma is a rarely seen complication. The authors describe a case of subcutaneous neoplastic seeding in a 70-year-old woman with chronic hepatitis C virus complicated by hepatocellular carcinoma. Ultrasonically guided fine-needle aspiration biopsy was performed in segment II of the liver. The neoplastic seedi...

This study aims to present the origins and the historical evolution of fine-needle aspiration biopsy and to also underline its importance in the history of modern cytology. The article focuses on the advances made in the 20th century that have led to the modern techniques associated with the procedure. The authors conducted a thorough review of early reports on needle biopsy, particularly those...

BACKGROUND Good cytological sample is very important for the cytological diagnosis of thyroid nodules. The aim of this study was to evaluate the adequacy of prepared samples by the combination of aspiration and non- aspiration fine needle biopsy. METHODS In this descriptive - analytical study, sampling was done simultaneously for each patient in fine needle aspiration and non-aspiration biops...

BACKGROUND The quality of liver biopsy specimens obtained with different fine needle biopsy (FNB) techniques has not been compared. OBJECTIVES This study was performed to evaluate the diagnostic quality of three different liver FNB biopsy techniques. MATERIALS AND METHODS Two sequential biopsy series were performed on piglets. Three biopsy techniques were compared: capillary-FNB, core-FNB (...

The diagnostic value of combined radiology and fine needle aspiration cytology (FNAC) was retrospectively assessed in a consecutive series of 52 patients with high-grade osteosarcoma. The series was divided into typical and atypical osteosarcomas according to radiological features and site. Thirty-two of 33 radiologically typical osteosarcoma cases were correctly diagnosed by cytology; one lesi...

BACKGROUND Fine needle aspiration biopsy (FNA) is a routine diagnostic technique for evaluating thyroid nodules. Many reports in adults consider that FNA is superior to thyroid ultrasonography (USG) and radionuclide scanning (RS). Only five studies have been published on FNA of childhood thyroid nodules. AIMS To investigate the reliability of FNA in the evaluation and management of thyroid no...

Fine needle aspiration biopsy (FNAB) was performed in 46 patients with an orbital mass. Positive cytological identification was made in 43 biopsy specimens. In 26 cases with histopathological control the accuracy was 81%. In experienced hands FNAB is safe and appears to be a valuable tool in establishing a diagnosis of malignancy in orbital tumours.

Prostatic massage specimens are not consistent in producing adequate material. Also, the possibility of contamination from other parts of the urinary tract cannot be discounted. It is of no value in latent or occult carcinoma (6, 13, 22), though some authors have been highly successful in the diagnosis of prostatic carcinoma by this method (16). Popular concensus of opinion agrees that 85-950/o...
