Background
Bladder cancer is the most common malignancy in the urinary tract. Urothelial carcinoma is the most common histologic
type of bladder cancer in the United States, accounting for approximately 90%. Nonurothelial bladder cancers are less common, comprising approximately 5% of all bladder cancers. In parts of the world where infection with Schistosoma haematobium is prevalent, squamous cell carcinoma is the most common bladder cancer, responsible for approximately 50%
of all bladder cancers. In North America, however, squamous cell carcinoma is less common, making up only 3-5% of
bladder cancers. We present a case of squamous cell carcinoma of the bladder in a female associated with multiple bladder
stones.
