title: Oliguria, an unusual presentation of primary signet ring-cell adenocarcinoma of the urinary bladder: a case report and review of the literature.
abstract: Adenocarcinomas represent approximately 2% of primary bladder epithelial malignancies. Of these, the signet ring-cell variant is the rarest form. We report such a case, with the unusual presentation of oliguria, including radiologic and histopathologic findings. The current literature is reviewed.
