چکیده

Primary tumors of the appendix are rare, while malignant villous adenoma of the appendix invading the urinary bladder is extremely uncommon. We reported the present case of a 63-year-old male with malignant villous adenoma of the appendix invading the urinary bladder. The conventional cystoscope demonstrated a mass at the front right side wall of the urinary bladder, which misdiagnosed as bladder cancer initially.

At the intraoperative exploration and pathology, malignant villous adenoma of the appendix invading the urinary bladder was verified.
