Mullerianosis of the urinary bladder

Endometriosis is the ectopic presence of endometrial tissue outside of the uterus. Bladder involvement of these lesions is not uncommon and has been reported and studied extensively. Mullerianosis is a term that describes the ectopic presence of tissues from the endocervix and endosalpinx in extrauterine sites. Only a few cases of Mullerianosis involving the urinary tract system have been reported in literature. We report a case of a 32-year-old lady with bladder mass and periodic hematuria and dysuria. She underwent TURBT (1)and on histopathology was found to have bladder Mullerianosis. Patient was later treated with oral contraceptives with improvement.
