Argyrophilic Nuclear Organiser Regions (AgNORs) Pattern in Different Grades of Transitional Cell Carcinoma of Urinary Bladder

case. Results: The AgNOR size in grade II was predominantly of 2+ while AgNOR size in grade III was predominantly of 3+.A significant higher proportion of cases (p < 0.02) with 3+ AgNOR dispersion were seen in grade III carcinoma. Conclusion: AgNOR size and AgNOR dispersion were found to be an easy and reproducible alternative to traditional AgNOR counts in grading of transitional cell carcinoma. The demonstration of AgNOR dispersion is also a simple and cost effective procedure.
