title: Primary signet-ring cell carcinoma of bladder.
abstract: Patients presenting with rare primary signet-ring cell carcinoma of the bladder are often found to be in renal failure and to have distressing symptoms of bladder instability. Their clinical course most often is rapidly fatal, and radical cystectomy with urinary diversion offers the only hope of increasing longevity. We herein review the literature of this rare variant of bladder adenocarcinoma and present a case in which a unique form of urinary diversion reversed the uremic state and increased this patient's longevity.
