Cytology Collection Manual CYTOLOGY LABORATORY Hours of operation: University of Florida Health Pathology Laboratories Monday – Friday | 8 a.m. – 4:30 p.m. The Microscopy method used in the laboratory uses an analyser to estimate the number of white and red blood cells, and the number of bacteria in urine to help to distinguish infection from contamination. Urine cytology - squamous cells and urothelial cells. We frame this chapter in terms of the total testing process (TTP), which is briefly outlined in the introduction. All funds raised will be allocated to the RCPA Foundation Pathology Education Outreach Fellowship. Andrew A. Renshaw, in Cytology (Third Edition), 2009. The International Academy of Cytology is a organization of cytopathologists, cytotechnologists and other professionals concerned with research in and practice of clinical cytology. Bladder washings: if clinically indicated this method of collection may be superior to voided urine. Biomarkers applied on urine sediment smears of such patients are likely to be clinically relevant. ​​​​​​​Events and Grants Coordinator ... Anatomic Pathology Board Review (1st ed.).

Vollmer, MD,2 Bruce Case, MD,1 Armen Aprikian, MD,3 Wassim Kassouf, MD,3 and Manon Auger, MD1 What is the most likely etiology? Ideally at least three mid-morning or random specimens should be submitted for examination. If collected by urinating into a sterile container, this non-invasive procedure bears no risk. It is effective in detecting high grade cancers but has limited value in detecting low grade tumors. Background. We have merged the Parathyroid chapter into the Thyroid chapter. Disadvantages are the same as for catheterised specimens. 28 All urine specimens were processed as 2 cytospin ... seen these changes (irregular nuclear outlines, nuclear. A voided urine sample from a 50 year old woman shows urothelial cells admixed with histiocytes with round, laminated and basophilic cytoplasmic inclusions. Donate online now using the button below. Events and Sponsorship Manager “clean catch”) – Analyzed within 2 hours of collection – Free of debris or vaginal secretions The pathologist will send the results of your urine cytology test to your doctor, who will report the results to you.Ask your doctor how long you can expect to wait for your results.Different labs have different ways of describing the results of a urine cytology test. Urine cytology is the examination of cells in urine under a microscope. RCPA Foundation thanks you for your generous support. Detection of inflammatory lesions including specific infections, urinary crystal and calculi disease, iatrogenic changes and neoplasms of the urinary tract. The Paris System Working Group, organized at the 2013 International Congress of Cytology, conceived a standardized platform on which to base cytologic interpretation of urine … Catheterised specimens: may be submitted if clinically indicated. Saunders. (A) Voided-urine liquid-based cytology shows an increased nuclear-to-cytoplasmic ratio compared with noncancerous samples and irregular nuclear outlines, but these changes are subtle. 5-17 The Paris System for Reporting Urinary Cytology proposes a standardized terminology 18-23 that only seeks to diagnose high‐grade UC. Urine analysis in pathology clinical 1. Cytopathology, often called cytology, is the study of pathologic changes in cells.. Specimen types include exfoliated cervical cytology (Pap tests), urine, body cavity fluids (pleural, pericardial, and peritoneal), cerebrospinal fluid, and fine needle aspirations from any body site, among others (see detail articles section).These are often collected by minimally invasive means. The main purpose of this Manual is to provide useful guidelines for the selection of pathology tests and to facilitate interpretation of results. We are a truly independent pathology practice. INTRODUCTION. A mid-morning or random specimen is recommended with the sample being sent to the laboratory quickly for processing. Talk to … This article deals only with urine cytopathology. What is urine cytology ? Urine. LabCorp test details for Urine Cytology. © Copyright PathologyOutlines.com, Inc. Click, Rosenthal: The Paris System for Reporting Urinary Cytology, 1st Edition, 2016, Madame Curie Bioscience Database: Urine Cytology Findings of Polyomavirus Infections [Accessed 3 November 2020], Koss: Koss' Diagnostic Cytology and Its Histopathologic Bases, 5th Edition, 2005, Benign and reactive cytologic changes based on the Paris System for Reporting Urinary Cytology include nonneoplastic entities such as changes associated with lithiasis, bacterial, fungal and parasitic infections, viral cytopathic effect and posttreatment effect, Nonneoplastic entities may mimic malignant cells; clinical correlation, as well as the use of ancillary testing when needed, is advised, The Paris System for Reporting Urinary Cytology is the recommended system to report results (, Negative for high grade urothelial carcinoma category encompasses nonneoplastic entities that pose no significant risk for the development of high grade urothelial carcinoma, including, Changes associated with urinary lithiasis, Bacterial, fungal and parasitic infections, Atypical urothelial cells category should be used only if there are cellular alterations (mild to moderate cytologic atypia) that warrant concern but fall short of suspicious for high grade urothelial carcinoma or high grade urothelial carcinoma categories, Urinary bladder, upper tracts (renal pelvis, ureters), urethra, Urinary bladder diversion (ileal conduit, Indiana pouch, neobladder), 60 year old man with cytologic effects of intravesical mitomycin in urine cytology (, 67 year old woman with fusariosis in urine cytology (, 68 year old woman with adenovirus cytopathic effect in urine cytology of ileal conduit (, 74 year old woman with herpes simplex viral cytopathic effect in catheterized urine cytology (, 3 dimensional pseudopapillary clusters of urothelial cells, Rim of cytoplasm (collarette) around clusters, Urothelial cells with uniform round nuclei, finely granular chromatin and inconspicuous nucleoli; however, reactive atypia (pleomorphism, coarsely granular chromatin, hyperchromasia, occasional mitotic figures) can be seen, Background of blood or inflammatory cells, Urothelial cells with reactive changes: slight nuclear enlargement, conspicuous nucleoli but chromatin is fine and uniformly distributed and nuclei remain round, Note: presence of bacteria without neutrophils is a nonspecific finding, Histolytic inflammatory condition, often resulting from bacterial infection, Basophilic, concentric, laminated structures (Michealis-Gutmann bodies), Most common cause of fungal urinary tract infections, Reactive urothelial cells and mixed inflammatory background, Other less common fungal organisms reported in urine cytology, Classic appearance: infected cells with single, large, homogenous, basophilic, glassy nuclear inclusions and small condensed rim of chromatin, Central nuclear inclusion surrounded by irregular and incomplete clear halo (cytomegalovirus-like), Granular chromatin, sometimes multinucleated, Degenerated, vesicular nuclei with coarsely granular and clumped (spider web) chromatin, nucleoli can be seen, Round or oval, smooth but thickened nuclear membrane, Note: infected cells are descriptively known as decoy cells because they mimic malignant cells (, Similar to cells with polyomavirus cytopathic changes, Ground glass inclusions with margination of chromatin, Infected cells are markedly enlarged and have both nuclear and cytoplasmic inclusions, Nuclear inclusions: single, large, basophilic, surrounded by halo (owl's eye appearance), Cytoplasmic inclusions: multiple, smaller, basophilic, finely or coarsely granular, Infected urothelial cells show multinucleation, nuclear molding, homogenous, ground glass nuclei with margination of chromatin, Infected cells show koilocytosis, dyskeratocytosis, multinucleation, Pear shaped parasites with small and oval nucleus and red cytoplasmic granules, Urothelial cells show significant cytomegaly and nucleomegaly but maintain N/C ratio (not increased), Multinucleation and nuclear and cytoplasmic vacuoles may be seen, Nucleus and cytoplasm often have degenerative changes, Finely granular chromatin and smooth nuclear membrane, Cytologic changes can be seen for weeks to years, Intravesical Bacillus Calmette-Guérin (BCG) immunotherapy can cause granulomatous inflammation, Granulomas composed of epithelioid histiocytes with carrot shaped nuclei and lymphocytes, Langhans type multinucleated giant cells from fused macrophages have small, hyperchromatic nuclei clustered at one cytoplasmic pole, Intravesical treatment usually affects superficial cells, Nuclear enlargement, multinucleation and hyperchromasia, Systemic treatment may cause similar cytologic changes as intravesical mitomycin and thiotepa, Hyperchromasia, degeneration, large nuclei and increased N/C ratio, Negative for high grade urothelial carcinoma, Urothelial cells with viral cytopathic effects consistent with polyomavirus, Homogenous chromatin with ground glass appearance.
