Abstract: | A primary neoplasm arising in a vesical diverticulum was cystectomizedand analyzed by step-sectioning of the whole bladder in an attemptto determine the carcinogenic process. Serial sections of thecystectomy specimen revealed a small area of mild dysplasiain the mucosa of the bladder and the diverticulum without atumor. Most of the mucosal cells in the tumor-bearing diverticulumwere desquamated, but a small area of dysplasia in the remainingcells was also observed. |
