title: Metastatic umbilical mass from transitional cell carcinoma of the bladder.
abstract: We present the case of an 83-year-old female presenting with an umbilical mass measuring 2 cm x 3 cm. This patient had an extensive prior history of transitional cell carcinoma of the bladder. A fine needle aspiration of this umbilical mass confirmed this to be metastatic transitional cell carcinoma and the diagnostic workup demonstrated the presence of invasive bladder cancer with metastatic liver lesions.
