Core Tip
Core tip: Villous adenoma coexisting with adenocarcinoma of the urinary system is uncommon. Differential diagnosis from villous adenoma of the digestive tract is difficult. We present a case of villous adenoma coexisting with adenocarcinoma of the female urethral orifice and provide an accurate method to differentiate villous adenomas of the urinary and digestive tracts.
