The symptoms often include abdominal pain and hematuria. The standard treatment method is surgical excision of the tumor and sometimes, in advanced cases, chemotherapy is needed, too. Case Presentation : We present a 35-year-old male patient, who referred with acute onset of painless macroscopic hematuria. Pelvic CT scan showed a large mass on the bladder dome, extending to the umblicus. Biopsy of the mass confirmed that the pathologic diagnosis was urachal adenocarcinoma. The patient was then treated surgically with partial cystectomy approach. Conclusions : Despite microscopic involvement of pelvic lymph nodes, adjuvant therapy was not intended. There were no local recurrence or distant metastasis in long term close follow up. http://numonthly.com/en/articles/81471.html https://cdn.neoscriber.org/cdn/dl/2e9aedd2-c0fd-11e8-89b7-4bc1415c782e
