Objective: To find out the utility of The Paris System (TPS) in reporting urine cytology and to compare it with the reporting system currently used in our laboratory. Study Design: This retrospective study was undertaken over a period of 1 year during which slides of all the urine specimens sent for cytological examination were retrieved from our laboratory filling system. They were blindly reviewed and reclassified according to TPS. Surgical follow-up was obtained from the uropathology services of our department. Results: A total of 176 cases were meticulously reviewed. The mean age of the patients was 52 years, and 71% of cases presented with hematuria. Histopathological follow-up was available in 34 cases. Reporting by TPS detected 13.0% high-grade urothelial carcinoma (HGUC) and 5.1% atypical urothelial cells versus 7.3 and 11.9% by the current reporting system, respectively. The sensitivity and diagnostic accuracy for detecting HGUC of TPS were higher than those of our reporting system. Conclusion: TPS has increased the rate of detection of HGUC and reduced the rate of reporting “atypical” urothelial cells. TPS has also standardized the diagnostic criteria, thereby bringing uniformity and reproducibility into the system of reporting for urine cytology.

Background: Fibroepithelial lesions of the breast include fibroadenoma (FA) and phyllodes tumor (PT). Fibroadenomas are benign while phyllodes tumor range from benign, indolent neoplasms to malignant tumors capable of distant metastasis. Our study was to determine the select cytologic features that can accurately distinguish FA from PT. Methods: A retrospective review was performed of patients who had histopathology follow up of FA or PT and on whom a pre-operative fine needle aspiration was performed. Cytologic criteria i.e. epithelial component, stromal component and background cellularity were assessed. Results: 46 FA and 24 PT were specimens were reviewed. Median age and tumor size for FA and PT were 23.0 and 39.0 years, and 2.0 and 5.0 cm, respectively. Univariate analysis and regression models based on generalized estimating equations revealed that large opened out, folded epithelial sheets, frayed and irregular stromal fragment contours, spindle stromal cell nuclei, spindle cell nuclei in the background and background cell atypia are significant cytological predictors of PT. The GEE regression model achieved 78.9% diagnostic accuracy (p < 0.001) in identifying PT based on cytological features. Median epithelial: stromal ratio was 3.4 and 2.6 for FA and PT, respectively. Conclusion: Presence of large, opened out, folded epithelial sheets, frayed and irregular stromal contours with spindle nuclei, background spindle cells and atypia can help distinguish PT from FA.

Background Fine‐needle aspiration cytology (FNAC) is an established technique for preoperative diagnosis of salivary gland lesions; however, lack of a uniform reporting system has been a handicap. The main aims of this study were to evaluate the utility of the – “The Milan System for Reporting Salivary Gland Cytopathology” (MSRSGC) and ascertain the risk of malignancy (ROM) for each category. Methods All salivary gland FNACs over 5 years (January 2014‐December 2018) were reviewed and assigned a diagnostic category from the MSRSGC. Clinical data were taken from Cytology records. Cytodiagnosis was correlated with histopathology wherever available and ROM was calculated. Results A total of 120 salivary gland FNACs were studied. Age ranged between 5 and 85 years, male:female ratio was 2:1 and parotid was the commonest gland aspirated. Cases were reclassified as I non‐diagnostic (2.5%), II non‐neoplastic (15%), III atypia of uncertain significance‐AUS (1.7%), IV A neoplasm benign (50%), IV B neoplasm of uncertain malignant potential (12.5%), V suspicious for malignancy (5%), and VI malignant (13.3%). Follow‐up was available in 70 (58.3%) cases. The sensitivity, specificity, negative predictive value, and positive predictive value were 92.3%, 100%, 100%, and 98.27% respectively. ROM was non‐neoplastic (0%), AUS (50%), neoplasm benign (0%), neoplasm of uncertain malignant potential (28.6%), suspicious for malignancy (100%), and malignant (100%). Conclusion Salivary gland FNAC is a reliable diagnostic tool and the “Milan system” will further increase FNA reliability, help risk stratification, and improve patient care.
