[Mullerianosis of the urinary bladder: a rare entity].

OBJECTIVES To report a new case of bladder mullerianosis. METHODS We present the case of a 30 year old female patient with history of miscarriage, who refers voiding dis-turbances with menstruations. Vaginal ultrasound showed an exophytic bladder lesion, which was confirmed by cistoscopy. Endoscopic resection was indicated. RESULTS The pathological study of tissues obtained showed mixed glandular structures with predominant tubaric-like type, in association with endometrial- and endocervical-like elements. No evidence of endoscopic relapse after one year of follow-up. CONCLUSIONS We contribute with a new case of bladder mullerianosis. We emphasize the scarcity of its published reports. We support the option of an endoscopic surgery for these patients.
