INTRODUCTION Fine needle aspiration cytology (FNAC) is a reliable diagnostic tool used to diagnose breast lesions preoperatively. However, FNAC is also associated with diagnostic pitfalls. Further studies are needed to improve its diagnostic efficacy. We noticed ovoid, bare nuclei arranged in closely touching diads (benign pairs) in a significant number of cytology smears. This prompted us to a...

BACKGROUND AND STUDY AIM  Different types of endoscopic ultrasound (EUS)-guided fine-needle aspiration (FNA) techniques are used in clinical practice; the best method in terms of outcome has not been determined. The aim of the study was to compare the diagnostic adequacy of aspirated material, and the cytopathological and EUS morphological features between capillary action, suction, and no-suct...

Telepathology is useful when distance is an obstacle to timely diagnosis. Performance of fine-needle aspiration (FNA) at locations distant from cytopathologists can limit timely assessment of adequacy and preliminary diagnosis. We evaluated a telepathology system for consultation between residents and faculty for assessment of FNA specimen adequacy and preliminary diagnosis using 100 consecutiv...

BACKGROUND Unclear cervicofacial masses are common presentations that often require tissue sampling to guide therapy. While open biopsy is invasive, fine-needle aspiration cytology includes a high rate of nondiagnostic samples. METHODS A retrospective analysis on 181 core-needle biopsies in 88 patients was performed to determine the diagnostic efficacy of ultrasound-guided core-needle biopsie...

The successful diagnosis and treatment of cancerous growths requires as timely and non-invasive a procedure as possible. Epithelial tumors are often more readily accessible as they are on or adjacent to the lumen wall of the GI and vocal tract. The endomicroscopy of these cells' lesions can provide both the localization and the type of cancer, if any. The more conventional technique for this is...

Ultrasound is the most useful imaging technique for guiding biopsies and fine-needle aspirations that are performed percutaneously. It is a safe and accurate method to guide needles using real-time imaging into abdominal and pelvic organs and masses. Its advantages over computed tomography-guided biopsies are that it can be done portably, is less expensive, and does not use ionizing radiation. ...

Thyroid large needle aspiration biopsy is disregarded because it is thought to be associated with pain. This is in contrast with our 32 years long experience. We surveyed reports of pain in patients examined with fine needle aspiration biopsy (78, 87.2% women, mean age 59 years) or FNAB+large needle aspiration biopsy (48, 87.5% women, mean age 60 years). Each patient was questioned regarding a)...
