Bladder cancer. Light micrograph of a section through a transitional cell carcinoma (TCC) of the bladder. TCCs are malignant tumours that arise from the transitional epithelium lining the blad- der. Unlike normal epithelial tissue these cells are poorly differentiated and contain large, dark- staining nuclei - typical of rapidly dividing cells. TCCs vary from well-differentiated, less malignant papillomas to highly aggressive, poorly differentiated carcinomas. Cancer of the bladder accounts for 5% of all UK-diagnosed cancers. The disease tends to recur and is often fatal. Stained with hematoxylin and eosin. Magnification x125 at 35mm size.
