[Papillary urothelial carcinoma of the urachus].
OBJECTIVE
Persistence of a patent urachus is a relatively rare occurrence; however; the persistence of urachal remnants is common. The pathologic lesions of the urachus include benign and malignant neoplasms. The majority of malignant urachal neoplasms are adenocarcinomas.


RESULTS
We report a case of papillary urothelial carcinoma of urachus in a 73-year-old woman. The patient was treated with complete surgical extirpation and partial cystectomy.


CONCLUSIONS
The recognition of urachal remnants as vestigial structures and pathologic lesions of the urachus is important.
