The lesion was first described in 1996 by Clement and Young.\nClinical Features\n-\nIncidence\nMüllerianosis of the urinary tract is a rare lesion and it occurs in approximately 1% of women with endometriosis; the bladder is the organ most frequently involved (Raspollini and Lopez-Beltran 2019). Its pathogenesis is still a source of debate ranging between an embryological origin, metaplasia, and implantation during surgery.\n-\nAge\nMüllerianosis affects mainly reproductive age women.\n-\nSex\nIt is a finding mainly in women. Uncommon cases may occur in male patients under long-term estrogen therapy.\n-\nSite\nThis lesion occurs mainly in the dome or posterior wall of the urinary bladder.\n-\n...\nReferences and Further Reading\nBatt, R.
