Abstract

 

Primary adenocarcinoma of the urinary bladder is a rare neoplasm sometimes causing  diagnostic challenge because it can be indistinguishable morphologically from adenocarcinoma secondarily involving the bladder by metastasis or direct extension.  Identifying the primary origin of the tumor is important in staging, determining appropriate therapy and assessing prognosis.  We report herein a case of  primary adenocarcinoma of the  bladder misdiagnosed as metastatic adenocarcinoma and reviewed the histopathologic features and diagnostic characteristics of  primary adenocarcinoma of  bladder in view of literature.
