Urachal cancer is a rare form of cancer that can sometimes involve the bladder but does not arise from the urothelium and is therefore not bladder cancer in the usual sense. The disease arises from malignant transformation of rests of enteric epithelium in the urachus an embryonic structure located between dome of the bladder and the umbilicus. Urachal cancer can occur at any site along the urachal tract. The most common locations are the umbilicus and the dome of the bladder.
