Background: The present study was carried out to describe the Histopathological features of various neoplasms in the urinary bladder biopsies and to categorize the neoplastic lesions according to W.H.O (2016)/ISUP classification of urinary bladder tumors.
Materials and Methods: A total of 37 cases, 28 urinary bladder biopsies (TURBT) and 9 cystectomy specimens of urinary bladder neoplasia [histologically proved] of patients were studied retrospectively over the period from June 2016- Oct 2018 in Pathology department of Smt. N.H.L. medical college. All cases of urothelial carcinomas were graded histologically according to WHO (2016)/ISUP classification.
Results: Maximum numbers of patients are in age group 60-69 years. Males (78.37%) are more frequently affected as compared to female. The most frequent Neoplastic findings in Urinary bladder is Invasive Papillary Urothelial carcinoma (81.06%); Low grade (37.8%) being more common than High grade (35.14%). A large percentage (80%) of high grade invasive urothelial cell carcinomas presented with muscle invasion.
Conslusion: Invasion to the muscle propria layer correlates with high grade tumor. In 18.5% cases detrusor muscle was absent, hence the importance of including detrusor muscle in the biopsy specimens needs to be emphasized. We must accept the fact that grading is highly subjective and that in future various molecular and immunohistochemical studies will provide better reproducibility.
Keywords: Invasive papillary urothelial carcinoma, Muscle invasion, Urinary bladder neoplasms.
