Malignant villous adenoma of the appendix invading the urinary bladder: a case report
نویسندگان
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. Computed tomography (CT) and ultrasound especially contrast-enhanced ultrasonography (CEUS) preoperatively revealed a malignant mass originating from the appendix, but not the bladder. At the intraoperative exploration and pathology, malignant villous adenoma of the appendix invading the urinary bladder was verified.
