Mucinous cystadenoma of the dome of urinary bladder: A rare case report.

Mucinous cystadenoma of the urinary bladder is a very rare tumor and only a handful of cases have been described in the literature. It can easily be missed on cystoscopic examination as the lesion is not intramucosal. In addition, extensive workup is required to rule out borderline or frank malignant neoplasm elsewhere in the body. Due to its scarcity and diagnostic challenges, we report a mucinous benign cystic lesion arising in the dome of the urinary bladder.
