Squamous cell carcinoma of the urinary bladder is a malignant neoplasm derived from bladder urothelium with pure squamous phenotype.[1, 2, 3] Squamous cell carcinoma of the bladder is essentially similar to the tumors arising in other organs. Because many urothelial carcinomas contain a minor squamous cell component, a diagnosis of squamous cell carcinoma of the bladder should be rendered only when the tumor is solely composed of a squamous cell component in the absence of a conventional urothelial carcinoma component.
