Abstract
Mullerianosis of the bladder is a rare pathological condition characterized by the presence of residual Mullerian ductal tissue in the bladder wall. Although usually benign, Mullerianosis of the bladder may show tumor-like features and lead to potential misdiagnosis as bladder carcinoma.In this case report, we discuss a 53-year-old woman who presented with left flank pain, and an incidental bladder USG revealed a mass. Cystoscopy revealed a mucinous mass on the posterior wall, and histopathological examination revealed Mullerian type epithelium, confirming the diagnosis of Mullerianosis. The lesion recurred in two more control cystoscopies within two years.This case highlights the importance of considering Mullerianosis in the differential diagnosis of bladder lesions mimicking adenocarcinoma.
