Mullerianosis vesical

Müllerianosis of the urinary bladder, a rare entity, was first defined by Young and Clement in 1996 as the combination of at least two types of ectopic tissue of Müllerian origin (endometriosis, endocervicosis, and endosalpingiosis) in the bladder wall. Theories of implantation or metaplasia have been proposed to explain the origin of this entity. Recurrent or cyclic symptomatology, which is reported in up to 50% of patients, is highly suspicious of müllerianosis of the bladder. Although transurethral resection is useful in diagnosis, complete removal of the lesion (partial cystectomy) is highly advisable, as performed in the patient presented herein.
