Villous adenoma of the prostatic urethra.

Primary villous adenoma originating from the urinary tract is an infrequent entity. We present a rare case of villous adenoma arising from a prostatic urethra with no sign of malignant transformation. Villous adenoma should be considered as one of the differential diagnoses of urethral lesions, especially if it has similar magnetic resonance imaging features as its colonic counterpart. Due to its potential for malignant transformation, its complete resection is mandatory.
