The H&E sections from bladder wall of a benign bladder diverticulum with completely denuded urothelium (upper tissue edge), showing hypertrophic muscularis mucosae (A and B). C and D are from the conventional (lesion not arising from diverticula) neoplastic bladder wall of a well-differentiated squamous cell carcinoma, showing hypertrophic muscularis mucosae. Low (A, C – 40X) or higher magnifications (B, D – 100X), respectively.
