Needle core biopsy is a key tool in diagnosis and assessment of many medical liver diseases, but there is evidence that the combination of small size of the specimen obtained and the patchy nature of many of these diseases can result in misdiagnosis or incorrect staging. The Royal College of Pathologists has therefore published guidelines for assessment of adequacy. To assess whether these guid...

BACKGROUND AND STUDY AIMS The optimal core biopsy needle for endoscopic ultrasound (EUS) is unknown. The principle aim of this study is to compare outcomes of EUS-fine-needle biopsy (EUS-FNB) with a new 19-gauge EUS histology needle (ProCore, Cook Medical Inc., Winston-Salem, North Carolina, United States) to a conventional 19-gauge Tru-Cut biopsy (EUS-TCB) needle (19G, Quick-Core, Cook Medical...

Ataxia telangiectasia (AT) homozygotes have an increased risk for development of malignancies. Our patient, despite frequent courses of antibiotics, displayed persistent pulmonary infiltration, fever, and mediastinal enlarged lymph nodes on thoracic computed tomography. No infectious etiologies were established for the persistent pulmonary findings by fine needle biopsy, bronchopulmonary lavage...

Endoscopic ultrasound is an important innovation in the field of gastrointestinal endoscopy and allows evaluation of many organs in the vicinity of the gastrointestinal tract. Endoscopic ultrasound-fine needle aspiration has been established to be an important tool in the management of pancreaticobiliary disease and is used for screening, staging, biopsy confirmation, and palliation. The accura...

BACKGROUND Preoperative diagnosis has become the standard in breast cancer (BC) management. Recently, ultrasound guided core needle biopsy (CNB) and stereotactic needle core biopsy have replaced fine needle aspiration cytology. Epithelial cell displacement (DE) occurs frequently after core needle biopsy (CNB) for breast cancer diagnosis. AIM Systematically review (between 1900 and 2008) the c...

OBJECTIVE To retrospectively examine the success and complication rates associated with image-guided percutaneous bone biopsy with a simulated Van Sonnenberg removable hub system. MATERIALS AND METHODS During a 3.5-year period, 27 bone lesions at different anatomic locations with an indication for biopsy based on plain film, computed tomography (CT) and/or magnetic resonance imaging (MRI) fin...

The purpose of this study was to evaluate the applica-bility of ultrasound-guided percutaneous biopsy for the diagnosis and differentiation of various pulmonary lesions in a Chinese population. A total of 338 pulmonary lesions were biopsied with 18-gauge cutting needles, guided by ultrasound, and sent for histopathological analy-sis. The ultrasonographic characteristics of these lesions, proced...
