Bladder endometriosis simulating a bladder tumor

Endometriosis is relatively frequent in females of menstrual age and consists in the appearance of active endometrial tissue at sites other than the uterine cavity (genital system or adjacent organs). Endometrial tissue has been described to colonize the urinary system, particularly the urinary bladder. The most common clinical features of vesical endometriosis are urgency and frequency, hypogastric pain and hematuria. We report on a case of vesical endometriosis whose presenting features were urgency and urinary incontinence. The urological work up disclosed a solid vesical mass. Cystoscopy was highly suggestive of endometrial submucosa formation which was confirmed by TUR.
