According to the Bethesda System for Reporting Thyroid Cytopathology (BSRTC), cyst fluid only (CFO) cases are classified in the non-diagnostic category. To date, no large study focusing on CFO has been conducted. To reassess the diagnostic significance of CFO, we compared CFO nodules with non-diagnostic nodules excluding CFO (ND-other). We reviewed the conventional thyroid smears of 715 CFO and 766 ND-other nodules. We compared the timing of and findings at re-aspiration, the histology of resected specimens, and the proportion of malignant nodules between the two groups...

BACKGROUND & AIMS: Endoscopic ultrasound (EUS) with fine needle aspiration (FNA) is the standard of care for tissue sampling of solid lesions adjacent to the GI tract. Fine needle biopsy (FNB) may provide higher diagnostic yield with fewer needle passes. The aim of this study was to assess the difference in diagnostic yield between FNA and FNB. METHODS: This is a multicenter, prospective randomized clinical trial from six large tertiary care centers. Patients referred for tissue sampling of solid lesions were randomized to either FNA or FNB of the target lesion...

Molecular diagnostics and cytopathology ideally are complementary medical services. When used together, they provide optimal benefit to patient care with the least risk of complications. However, many cytopathology laboratories are reluctant to bring in molecular tests, in part due to inexperience with regard to molecular test validation. This article is a brief review of the basic principles of molecular test validation as it applies to cytopathology samples. Regulatory constraints, practical considerations, and issues that are particular to cytopathology samples are discussed, along with a brief review of issues that pertain specifically to next-generation sequencing...

Intraocular lymphoma is a rare neoplasm that occurs only in the eyes and/or central nervous system. Diagnosis of intraocular lymphoma is difficult because its clinical manifestations mimic chronic uveitis. Pathological examination of the vitreous is one of the main diagnostic tools for intraocular lymphoma, but this is challenging due to the sparse cellularity and specimen degeneration. Here, we reviewed 33 cell block preparations from vitreous perfusion fluid in order to examine the significance of cytopathological findings for differential diagnosis using vitreous samples...

BACKGROUND: Whole-slide imaging in cytology is limited when glass slides are digitized without z-stacks for focusing. Different vendors have started to provide z-stacking solutions to overcome this limitation. The Panoptiq imaging system allows users to create digital files combining low-magnification panoramic images with regions of interest (ROIs) that are imaged with high-magnification z-stacks. The aim of this study was to compare such panoramic images with conventional whole-slide images and glass slides for the tasks of screening and interpretation in cytopathology...

OBJECTIVES: Preferential use of fine-needle aspiration (FNA) versus core needle biopsy (CNB) for distinguishing benign from malignant major salivary gland tumors is highly debated. The main disadvantage of FNA is lower sensitivity, whereas arguments against CNB include use of a larger bore needle and greater risk of complications. The aim of this study is to evaluate our experience performing ultrasound-guided (UG) FNA with selective use of CNB based on preliminary cytopathology, and to determine whether our preoperative diagnostic approach is more sensitive and specific than FNA alone-and at least as sensitive and specific as CNB alone...

BACKGROUND: Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is a well-established first-line invasive modality for mediastinal lymph node staging in lung cancer patients and in the diagnostic workup of patients with mediastinal adenopathy. With the current 21- and 22-gauge (G) EBUS-TBNA needles, the procedure can be limited by the degree of flexibility in the needle and the size of the lumen in tissue acquisition. OBJECTIVE: We report our initial experience with a first-generation flexible 19-G EBUS-TBNA (Flex 19G; Olympus Respiratory America, Redmond, WA, USA) needle with regards to efficacy and safety...

Thyroid nodules are very common, affecting 19%-67% of the adult population. However, about 10% of them harbor a malignant lesion. Consequently, the first aim in their clinical evaluation is to exclude malignancy. Fine-needle aspiration cytology (FNAC) represents the main diagnostic tool for the evaluation of thyroid nodules. However, FNAC has a main diagnostic limit, namely cellular atypias of indeterminate significance, which require surgical excision and histological examination to differentiate benign from malignant lesions...

Background The diagnostic yield of endoscopic ultrasound (EUS) guided fine-needle aspiration (FNA) is variable, and partly dependent upon rapid onsite evaluation (ROSE) by a cytopathologist. Second generation fine-needle biopsy (FNB) needles are being increasingly used to obtain core histological tissue samples. Aims Studies comparing the diagnostic yield of EUS guided FNA versus FNB have reached conflicting conclusions. We therefore conducted a systematic review and meta-analysis to compare the diagnostic yield of FNA with FNB, and specifically evaluating the diagnostic value of ROSE while comparing the two types of needles...

Within the Bethesda System for Reporting Thyroid Cytopathology (TBSRTC), category III (atypia or follicular lesion of undetermined significance (AUS/FLUS)) comprises specimens with heterogeneous features and the need for subcategorization has been reported. We compared the clinical features of two subgroups from within the category of AUS/FLUS to determine precise guidelines for clinicians who explain the results of fine-needle aspiration (FNA) to patients. Retrospective review was performed including data from all patients who underwent FNA with results reported as AUS/FLUS at a single tertiary hospital from January 2010 to August 2014...

Salivary gland cytopathology is a diagnostically challenging area with overlapping cytomorphological features between benign, malignant, and metastatic tumors. We report the case of 45-year-old male who presented with two swellings in right retroauricular and infraauricular region along with a palpable single right cervical lymph node. On ultrasonography of the neck, a possibility of malignant lesion was given. Contrast enhanced computed tomography of the head showed a large well-defined space occupying lesion in right temporooccipital region eroding the skull bone with both extra and intracranial extension...

Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) is the procedure of choice for the cytologic diagnosis of pancreatic masses. The specificity of EUS-FNA approaches 100%, but the sensitivity is still low, and the high rate of indeterminate (atypical and suspicious) and false-negative results needs improvement. KRAS gene is frequently mutated in pancreatic ductal adenocarcinoma (PDAC) (up to 90%), and mutation analysis of KRAS has been proposed as diagnostic biomarker of PDAC. In most laboratories, KRAS mutation testing is performed by Sanger sequencing or real time-quantitative polymerase chain reaction (RT-qPCR), but these methods may give false-negative results in routine samples, mainly due to low cellularity...

OBJECTIVES: The Bethesda System for Reporting Thyroid Cytopathology (TBSRTC) established diagnostic categories for cytologic specimens of the thyroid. Each category was associated with an estimated risk of malignancy. Recently, the non-invasive follicular variant of papillary thyroid carcinoma has been reclassified as benign. This reclassification may alter the malignancy risk of TBSRTC diagnostic categories. STUDY DESIGN: A literature search was made for all studies investigating the effect of reclassification of some non-invasive follicular variant papillary thyroid carcinomas as benign on the malignancy risk associated with TBSRTC categories...

Fine needle aspiration (FNA) biopsy is an important and widely accepted method used in the diagnosis of patients with thyroid nodules.The lack of consistency in reporting FNA taken from the thyroid gland has led to divergences in the calculation of the sensitivity and specificity of the method. Discrepancies depend on what was considered to be true or false negative/positive. This resulted in confusion among doctors, who had to decide how to manage the patient with constantly changing positive or negative results of the FNA...
