Urinary bladder carcinoma is a common urologic malignancy, particularly in males. We studied the role of smoothelin (a cytoskeleton protein) as a diagnostic marker for muscularis propria invasion, differentiating it from the muscularis mucosae for proper staging in urinary bladder carcinoma patients. Paraffin blocks from 85 cases of bladder carcinoma: 69 urothelial carcinoma cases, 10 squamous cell carcinoma cases, 5 adenocarcinoma cases and one case neuroendocrine small cell carcinoma, were stained by smoothelin immunohistochemical marker. Smoothelin proved an important diagnostic utility, allowing distinction of the muscularis propria MP (positive smoothelin expression) from the muscularis mucosa MM (negative smoothelin expression). The sensitivity and specificity of smoothelin in detecting MP invasion in the current study was 100%. It is important to use smoothelin immunohistochemistry as a routine in all cases of TURBT specimens for accurate staging and subsequent optimal patient management.
